New computer virus spreads from Ukraine to disrupt world business

A computer virus wreaked havoc on firms around the globe on Wednesday as it spread to more than 60 countries, disrupting ports from Mumbai to Los Angeles and halting work at a chocolate factory in Australia. Risk-modeling firm Cyence said economic losses from this week's attack and one last month from a virus dubbed WannaCry would likely total $8 billion. That estimate highlights the steep tolls businesses around the globe face from growth in cyber attacks that knock critical computer networks offline. "When systems are down and can't generate revenue, that really gets the attention of executives and board members," said George Kurtz, chief executive of security software maker CrowdStrike. "This has heightened awareness of the need for resiliency and better security in networks." The virus, which researchers are calling GoldenEye or Petya, began its spread on Tuesday in Ukraine. It infected machines of visitors to a local news site and computers downloading tainted updates of a popular tax accounting package, according to national police and cyber experts. It shut down a cargo booking system at Danish shipping giant A.P. Moller-Maersk (MAERSKb.CO), causing congestion at some of the 76 ports around the world run by its APM Terminals subsidiary..

Maersk said late on Wednesday that the system was back online: "Booking confirmation will take a little longer than usual but we are delighted to carry your cargo," it said via Twitter. U.S. delivery firm FedEx said its TNT Express division had been significantly affected by the virus, which also wormed its way into South America, affecting ports in Argentina operated by China's Cofco.The malicious code encrypted data on machines and demanded victims $300 ransoms for recovery, similar to the extortion tactic used in the global WannaCry ransomware attack in May. Security experts said they believed that the goal was to disrupt computer systems across Ukraine, not extortion, saying the attack used powerful wiping software that made it impossible to recover lost data. "It was a wiper disguised as ransomware. They had no intention of obtaining money from the attack," said Tom Kellermann, chief executive of Strategic Cyber Ventures.Brian Lord, a former official with Britain's Government Communications Headquarters (GCHQ) who is now managing director at private security firm PGI Cyber, said he believed the campaign was an "experiment" in using ransomware to cause destruction. "This starts to look like a state operating through a proxy," he said. Norton Support Number

Social media giants step up joint fight against extremist content

Social media giants Facebook, Google's YouTube, Twitter and Microsoft said on Monday they were forming a global working group to combine their efforts to remove terrorist content from their platforms. Responding to pressure from governments in Europe and the United States after a spate of militant attacks, the companies said they would share technical solutions for removing terrorist content, commission research to inform their counter-speech efforts and work more with counter-terrorism experts. The Global Internet Forum to Counter Terrorism "will formalise and structure existing and future areas of collaboration between our companies and foster cooperation with smaller tech companies, civil society groups and academics, governments and supra-national bodies such as the EU and the UN," the companies said in a statement. The move comes on the heels of last week's call from European heads of state for tech firms to establish an industry forum and develop new technology and tools to improve the automatic detection and removal of extremist content. The political pressure on the companies has raised the prospect of new legislation at EU level, but so far only Germany has proposed a law fining social media networks up to 50 million euros (44.03 million pounds) if they fail to remove hateful postings quickly. The lower house of the German parliament is expected to vote on the law this week.

The companies will seek to improve technical work such as a database created in December to share unique digital fingerprints they automatically assign to videos or photos of extremist content. They will also exchange best practices on content detection techniques using machine learning as well as define "standard transparency reporting methods for terrorist content removals."Earlier this month Facebook opened up about its efforts to remove terrorism content in response to criticism from politicians that tech giants are not doing enough to stop militant groups using their platforms for propaganda and recruiting. Google announced additional measures to identify and remove terrorist or violent extremist content on its video-sharing platform YouTube shortly thereafter.Twitter suspended 376,890 accounts for violations related to the promotion of terrorism in the second half of 2016 and will share further updates on its efforts to combat violent extremism on its platform in its next Transparency Report. The social media firms said they would work with smaller companies to help them tackle extremist content and organisations such as the Center for Strategic and International Studies to work on ways to counter online extremism and hate. All four companies have initiatives to counter online hate speech and will use the forum to improve their efforts and train civil society organisations engaged in similar work. Norton Support Number

George Brandis's salvo in cryptowars could blow a hole in architecture of the internet

In 1993 the US president Bill Clinton’s administration introduced the “Clipper chip” into America’s digital and consumer electronics. It was one of the earliest attempts to enforce a backdoor into digital products, and the first in what is known as the cryptowars, when the US government fought to control and regulate strong encryption. The Clipper chip was a catastrophic failure. It’s a failure the attorney general, George Brandis, may find instructive, as he places Australia on the frontline of a new cryptowar.This weekend Brandis sought to revive a debate that has continued for several years about granting governments greater access to encrypted messaging communication to aid criminal investigations. In an interview with Sky News, Brandis said he would approach the Five Eyes intelligence network – made up of the US, the UK, Canada, New Zealand and Australia – to ask them to consider imposing greater legal obligations on device makers and social media companies “to cooperate with authorities in decrypting communications”. He looked favourably at laws passed in the UK that require device makers and messaging providers to provide greater assistance to authorities in decrypting messages. Norton Support Number

Lenovo to offer free McAfee LiveSafe security software to users whose laptops were shipped with Superfish

Lenovo, the world's biggest personal computer maker, last week advised customers to uninstall the Superfish program.Security experts and the US Department of Homeland Security recommended the program be removed because it made users vulnerable to what are known as SSL spoofing techniques that can enable remote attackers to read encrypted web traffic, steal credentials and perform other attacks.Lenovo announced the offer to provide six-month subscriptions to Intel's McAfee LiveSafe on Friday as it also disclosed plans to "significantly" reduce the amount of software that it ships with new computers.Pre-loaded programs will include Microsoft Corp's (MSFT.O) Windows operating system, security products, Lenovo applications and programs "required" to make unique hardware such as 3D cameras work well, Lenovo said."This should eliminate what our industry calls 'adware' and 'bloatware,'" the Lenovo statement said. Adi Pinhas, chief executive of Palo Alto, California-based Superfish, said in a statement last week that his company's software helps users achieve more relevant search results based on images of products viewed. He said the vulnerability was "inadvertently" introduced by Israel-based Komodia, which built the application that Lenovo advised customers to uninstall.
Komodia declined comment.

Free Antivirus Panda 2016 Review

It may use the power of the cloud, but Panda's Free Antivirus still has an impact on system performance. But protection from viruses is excellent, and it adds in a couple of useful extra features. Here's our Panda Free Antivirus 2016 review Many of the big names in antivirus software offer free versions, but they're not always obvious when you visit their website as they'd prefer you to pay for a more comprehensive security suite.Here's our review of Panda's Free Antivirus 2016, which you can get for free by clicking here from Panda's website.Panda has revamped the look of its antivirus software and this goes for the free product as well as the paid-for ones. The main screen is a modern design with tiles for scanning statistics, a link to the dashboard, USB protection and process monitoring.These last two are unusual in an AV program.

 USB protection prevents apps from running automatically when you plug in a USB device and analyses file contents for malware, while process monitoring provides a simpler interface for the kind of info the Windows Task manager offers.Panda makes considerable claim for running most of its scanning in the cloud and having a very light touch on the PC platform its run on. This is something more and more of its competitors are now copying, but we didn’t notice any evidence of a low impact in our tests.A 50GB scan took 1 hour 57 minutes for a scan of 455,748, the second longest of all the free antivirus programs we've tested recently. This is not an undue worry for a first scan, as it’s during this task that most AV programs create a fingerprint of the files and know which ones not to retest unless they’ve undergone change between scans.What was more surprising was that our secondary scan, of the same set of files, still took 1 hour 17 minutes to examine 426,178 files. This is a clear indication that not much fingerprinting is being done and the software is still retesting a lot of files.

McAfee antivirus program goes berserk, freezes computers

Computers in companies, hospitals and schools around the world got stuck repeatedly rebooting themselves Wednesday after an antivirus program identified a normal Windows file as a virus.
McAfee Inc. confirmed that a software update it posted at 9 a.m. Eastern time caused its antivirus program for corporate customers to misidentify a harmless file. It has posted a replacement update for download.McAfee could not say how many computers were affected, but judging by online postings, the number was at least in the thousands and possibly in the hundreds of thousands.McAfee said it did not appear that consumer versions of its software caused similar problems. It is investigating how the error happened "and will take measures" to prevent it from recurring, the company said in a statement.The computer problem forced about a third of the hospitals in Rhode Island to postpone elective surgeries and stop treating patients without Norton Support traumas in emergency rooms, said Nancy Jean, a spokeswoman for the Lifespan system of hospitals. The system includes Rhode Island Hospital, the state's largest, and Newport Hospital. Jean said patients who required treatment for gunshot wounds, car accidents, blunt trauma and other potentially fatal injuries were still being admitted to the emergency rooms.In Kentucky, state police were told to shut down the computers in their patrol cars as technicians tried to fix the problem. The National Science Foundation headquarters in Arlington, Va., also lost computer access.Intel Corp. appeared to be among the victims, according to employee posts on Twitter. Intel did not immediately return calls for comment.

Peter Juvinall, systems administrator at Illinois State University in Normal, said that when the first computer started rebooting it quickly became evident that it was a major problem, affecting dozens of computers at the College of Business alone."I originally thought it was a virus," he said. When the tech support people concluded McAfee's update was to blame, they stopped further downloads of the faulty software update and started shuttling from Mcafee Helpline Number computer to computer to get the machines working again.In many offices, personal attention to each PC from a technician appeared to be the only way to fix the problem because the computers weren't receptive to remote software updates when stuck in the reboot cycle. That slowed the recovery.It's not uncommon for antivirus programs to misidentify legitimate files as viruses. Last month, antivirus software from Bitdefender locked up PCs running several different versions of Windows.However, the scale of this outage was unusual, said Mike Rothman, president of computer security firm Securosis.

NHS cyber-attack was 'launched from North Korea'

British security officials believe that hackers in North Korea were behind the cyber-attack that crippled parts of the NHS and other organisations around the world last month, the BBC has learned.
Britain's National Cyber Security Centre (NCSC) led the international investigation.
Security sources have told the BBC that the NCSC believes that a hacking group known as Lazarus launched the attack.The US Computer Emergency Response Team has also warned about Lazarus.
The same group is believed to have targeted Sony Pictures in 2014.The Sony hack came as the company planned to release the movie The Interview, a satire about the North Korean leadership starring Seth Rogen. The movie was eventually given a limited release after an initial delay.
The same group is also thought to have been behind the theft of money from banks.
NHS hit In May, ransomware called WannaCry swept across the world, locking computers and demanding payment for them to be unlocked Norton Support Number UK The NHS in the UK was particularly badly hit.
Officials in Britain's National Cyber Security Centre (NCSC) began their own investigation and concluded their assessment in recent weeks.The ransomware did not target Britain or the NHS specifically, and may well have been a money-making scheme that got out of control, particularly since the hackers do not appear to have retrieved any of the ransom money as yet.
Although the group is based in North Korea the exact role of the leadership in Pyongyang in ordering the attack is less clear.
Detective work
Private sector cyber-security researchers around the world began picking apart the code to try to understand who was behind the attack soon after.Adrian Nish, who leads the cyber threat intelligence team at BAE Systems, saw overlaps with previous code developed by the Lazarus group.
"It seems to tie back to the same code-base and the same authors," Nish says. "The code-overlaps are significant."Private sector cyber security researchers reverse engineered the code but the British assessment by the NCSC - part of the intelligence agency GCHQ - is likely to have been made based on a wider set of sources.America's NSA has also more recently made the link to North Korea but its assessment is not thought to have been based on as deep as an investigation as the UK, partly because the US was not hit as hard by the incident.Officials say they have not seen any significant evidence supporting other possible culprits.

Facebook reveals measures to remove terrorist content

The move comes after growing pressure from governments for technology companies to do more to take down material such as terrorist propaganda.In a series of blog posts by senior figures and an interview with the BBC, Facebook says it wants to be more open about the work it is doing.
The company told the BBC it was using artificial intelligence to spot images, videos and text related to terrorism as well as clusters of fake accounts."We want to find terrorist content immediately, before people in our community have seen it," it said.
No safe space
The ability of so-called Islamic State to use technology to radicalise and recruit people has raised major questions for the large technology companies.They have been criticised for running platforms used to spread extremist ideology and inspire people to carry out acts of violence.Governments, and the UK in particular, have been pushing for more action in recent months, and across Europe talk has been moving towards legislation or regulation.Earlier this week in Paris, the British prime minister and the president of France launched a Norton Helpline Number joint campaign to ensure the internet could not be used as a safe space for terrorists and criminals.Among the issues being looked at, they said, was creating a new legal liability for companies if they failed to remove certain content, which could include fines.Facebook says it is committed to finding new ways to find and remove material - and now wants to do more than talk about it."We want to be very open with our community about what we're trying to do to make sure that Facebook is a really hostile environment for terror groups," Monika Bickert, director of global policy management at Facebook, told the BBC.One criticism British security officials make is of the extent to which companies rely on others to report extremist content rather than acting proactively themselves.Facebook has previously announced it is adding 3,000 employees to review content flagged by users.But it also says that already more than half of the accounts that it removes for supporting terrorism are ones that it finds itself.

The Best Free Antivirus Software for Windows

If you have a Windows computer, you need anti-virus software. There always will be those who will insist that every virus attack is caused due to "user error" or because the person using the computer wasn't careful enough. That statement is only partly true. Even if you have all the latest Windows updates installed and are using the latest version of a secure browser, there are always some vulnerabilities can be used to attack your computer. Good anti-virus software stops you from downloading viruses or opening unsafe files. That's why it is essential to have anti-virus software installed and updated.Many computer dealers will ask you to buy a licence for an anti-virus suite along with the PC, but free anti-virus software along with an anti-malware programme form a line of defence that's good enough for most people.
We looked at tests conducted by PC Mag and independent testing body AV-Test as a starting point and weighed them against our our own experiences to compile this list of the best free anti-virus software for Windows. Here are our picks:
Avast 2015 Free Antivirus

Avast is easy to understand, uses simple language to explain any problems, and has a great user interface that anyone can follow. It simplifies things like updating to the latest version and keeping the virus list up to date. Use silent mode to avoid the excessive announcements.

Download Avast 2015 Free Antivirus

Panda Free Antivirus 2015
Like Avast, Panda scored top marks for virus protection in AV-Test's report. Its interface is pretty but not as user friendly as that of Avast. It also has a nice feature called USB Vaccine - this prevents virus attacks that occur when you plug in an infected USB drive.

Symantec Norton Security Service Launched for Windows, OS X, iOS and Android

Symantec has launched a new subscription antivirus service called Norton Security. The offering will be priced at Rs. 1,399 per year for a single PC or Mac. A Deluxe edition covering up to five PCs, Macs, smartphones or tablets will also be available for Rs. 2,999 per year, and a Premium edition which covers up to 10 such devices and also includes parental controls and 25GB of online backup space will cost Rs. 4,599 per year. As a limited period introductory offer, Symantec will sell the three packages for Rs. 749, Rs. 1,399 and Rs. 2,999 respectively for the first year.The company wants to simplify its product lineup which previously consisted of Norton Antivirus, Norton Internet Security and Norton 360. Symantec is positioning its new service as a solution for advanced current-day threats such as individualised phishing scams and man-in-the-middle attacks.At a pre-launch event in Mumbai, Gerry Egan, Senior Director of Norton Product Management at Symantec specifically highlighted ransomware attacks and cybercriminals who try to steal personal information as more relevant to current day security than just viruses.
Browser-based tools provide warnings to users about social engineering scams, potentially compromised websites, and drive-by malware downloads.Windows 10, 8.1, 7, Vista and XP are supported, as well as the current and previous two versions of Mac OS X. Android 2.3 or higher running the Google Play services and iOS 7 and later can run Norton Security. However, the Microsoft Edge browser and Windows 8 Modern UI apps aren't supported. The software will be available as a digital download only; Symantec will not offer boxed packages at retail.Norton Security leverages the company's global threat intelligence tools which monitor email messages, websites, and apps including app stores, to proactively identify breaches that might result in customers' personal data being compromised.Customers of Norton Security will get free 24/7 phone support. Symantec is so confident of its offering that is guaranteeing a 100 percent refund to customers if a breach occurs and one of the company's own engineers fails to remove the threat completely.Egan was also quick to distance the company's current offerings from those several years ago which were heavily criticised for slowing down PCs. Calling that an industry-wide problem, he characterised the performance impact of the new Norton Security service in terms of lag at boot time as less than one second. The program can run in the background and never really has to run a deep scan of the user's entire hard drive, since all incoming files are cleared at the time of creation. Norton Security can also use checksums to verify the integrity of known good files rather than scanning them entirely to detect changes Norton Antivirus Support

You don't really need an antivirus app for your Android phone: Google

Explaining how secure Android devices have become, Google's lead engineer for Android security, Adrian Ludwig, says that the company often scans for malware and has become so proficient at spotting them that there are now less than 1 per cent of Android devices with a malware problem.The Register, citing Ludwig, reports, "I'm conflicted about antivirus [for mobile]. It's tremendously valuable that all these security companies are doing this research, but for the end user the potential increase in value from a security standpoint is very small relative to the costs of space and storage and battery.That said, some people really want to run it and if it makes you feel better then by all means do it," he adds.He further says that the company's security systems scan every Android device at least once a week.Norton Support Number

Avast Warns of Cyber-Attacks on Routers and IoT Devices

Avast, the company behind the leading antivirus software, warned Thursday against attacks on home appliances connected to the Internet, calling hackers targeting home routers a major threat to consumers."It's a trivial thing to do and there's nothing the user can do to fix it, other than to throw the router away and put in a new router," Avast chief executive Vincent Steckler told reporters.
Avast chief technology officer Ondrej Vlcek said that more and more people were using Internet-enabled appliances which he described as "a total nightmare when it comes to security".
Vulnerable appliances include TV sets, audio systems, coffee machines and toys, according to the Prague-based company, which every month registers 444 million users and prevents 3.5 billion malware attacks and 500 million visits to harmful websites.In February, London police arrested a Briton suspected of staging a cyber-attack on household routers run by Deutsche Telekom in November 2016, which knocked an estimated million German households offline.Steckler said his company had hacked into a router at a recent show in the United States to demonstrate the harm such attacks can do.

Avast changed the router's firmware, took control of a TV set and made it play a Barack Obama speech over and over."Even if you turn off the TV, the router turns the TV back on and the user can't see anything other than the Obama speech," Steckler said, adding that the hacker could then hold the TV for ransom."I know most people, especially Americans, care much more about their TV than they do about their data. They'd probably be much more willing to pay ransom for it," he said, chuckling.
Internet security became a hot topic last Friday when a ransomware attack hit more than 300,000 computers worldwide, affecting the likes of Britain's National Health Service, US package delivery giant FedEx and Germany's Deutsche Bahn rail network Norton Helpline Number

Why you need antivirus and why do you need it?

Unless you’ve got some sort of security software installed, your Windows PC or laptop is vulnerable to viruses, malware and ransomware. The best solution is to install antivirus protection, and you'll be pleased to hear it doesn't have to cost you loads.Antivirus software detects, and then prevents, disarms or removes malicious programs or malware, often referred to as 'viruses'. Antivirus doesn't offer a perfect solution to the problem of malware, but it is a critical first step to securing your PC or laptop. To help prevent viruses infecting your PC you must install antivirus, and then regularly update your antivirus software. All the antivirus software reviewed here will update automatically.
But internet security software is no longer just about countering viruses. Although they still exist, viruses are arguably a minor part of the malware now prevalent on the web. More important now is security of personal data and protection from ransomware. Security exploits aren't about show-off hackers massaging their egos, anymore, but about monetising their malware.
The modern day criminal doesn't have to be a hard-line hacker, either. They can buy all the software they need, and millions of addresses, on the dark web or even on eBay, if you know where to look. You can buy everything from denial of service attack - with botnets for hire - to individual exploits. Custom attacks are available, where the code changes after only a dozen uses or so, making it very hard for Internet Security (IS) providers to block every new variant.
Zero day attacks
Although the primary concern is to block malware so it doesn’t install on your PC in the first place, there isn’t an internet security suite made which is 100 percent effective. Worthwhile IS and antivirus software should also detect so-called ‘zero day’ attacks, where the malware is so new it hasn’t yet been analysed or had ‘signatures’ built into IS protection routines.
The speed with which these analyses are made is an important factor in the level of protection an IS suite can provide. Some companies now claim a turnaround of well under an hour, using information gained from their own customers about similar attacks. The cloud element in security applications is growing more and more important in speeding this process. So-called "next gen" protection using behaviour analysis and even artificial intelligence is also beginning to creep into some products.

Why do you need Antivirus Protection

Antivirus insurance has progressed toward becoming as basic as PCs. Almost every PC has some sort of infection security introduced. The diverse kinds of security bundles change nearly as much as the distinctive brands of PCs. Regularly there are just a couple that are the well on the way to wind up on today's PC framework. Asking somebody what their most loved antivirus program is welcomes an attack of various names that are typically joined by much more differed reasons. Some like Avast, AVG, or Microsoft System Essentials on account of their cost, free. Others will gush off both well known and disagreeable names like Norton, McAfee, Kaspersky, Trend Micro and others. In the event that you ask the question for what valid reason they have their specific antivirus bundle the appropriate responses are significantly more various than the product bundles that exist.

The normal audit webpage found on the Internet while not generally terrible is typically offering a one-sided see toward what antivirus bundle is ideal. Which shows the topic of how on the planet does one settle on an educated choice on the sort of antivirus programming to pick? Antivirus programming falls into two fundamental classes, Free and Paid. Under these classes you will probably see they fall into subcategories, Antivirus Protection and Security Suites. In the Free classification finding a security suite is not likely. Normally the concentration of simply shielding you from malware and infections is the objective with inclusion of unobtrusive to obtrusive inciting of obtaining the paid variant of the product. In the paid classification security suites are normally the antivirus programming consolidated with the organizations adaptation of a firewall, online reinforcement and different sorts of administrations.

One classification that still can't seem to be said here and that is ending up noticeably progressively famous is Managed Antivirus assurance. Vast organizations utilize an IT staff to watch out for their PCs. Obligations incorporate a large number of various things from PC establishment, arrange checking, and regular programming establishment and repair.
