The effectiveness of antiviruses is often the subject of controversy: a discussion of the advantages and disadvantages of free software to protect PCs. To put an end to such discussions, the independent AV-Test laboratory decided to test 18 popular free antiviruses.
What is known about the best free antivirus
According to the specialists of the German company, the antivirus-winner — Microsoft Windows Defender — entered the top ten most effective antivirus programs and received maximum ratings in the categories of “usability” and “reliability of protection”, as well as 5.5 points out of 6 possible by the criterion of “performance “
Microsoft Windows Defender has demonstrated 100% protection against malicious attacks, including zero-day threats, as well as the absence of false locks and warnings.
Why Microsoft Antivirus is the Best
In particular, the application successfully recognized 20,428 virus samples recorded in the last 4 weeks before the test.
During testing, there were used the current version of the program with permission to access cloud services and the current version of signatures.
To test the effectiveness of the antivirus there were analyzed the operation of all its components using real threats. Experts also noted a low level of false positives — after analyzing 1,384,100 samples, the antivirus made a mistake in only two cases.
Where to download antivirus
Note that Windows Defender is already part of the Microsoft operating system and does not require a preliminary installation.

Based on the latest Avast blog post, a new method of producing malicious PDF files has been discovered by the avast team. This method allows malicious PDF files to be unrecognized by almost all antivirus scanners.
Yesterday [2011-04-11] a number of my clients called in the afternoon me in regards to some antivirus related activities on their computers. Something really weird was going on on all computers. Avast was flagging most of the websites as infected. There was nothing going on the PCs and even after a ran the AVAST scan and a couple of other anti-malware scans and did not find anything the website were kept on being blocked.
Luckily, after a definition upgrade on one of the PCs (by the way done by the CEO of the company) the issue was resolved. My clients use the Small business Server and Standard suites so the updates on the workstations was done almost within a few minutes simultaneously on all of the computers after which everything went back to normal.
It really took about a couple of hours between noticing a problem and solving it. I consider this is not as bad as it could have been.
I’m a bit surprised how quick Avast responded to the problem, solved the problem and also posted a blog describing it.
“Virus definition update 110411-1 contained an error that resulted in a good number of innocent sites being flagged as infected. Generally, all sites with a script in a specific format were affected.
Our virus lab staff discovered the problem quickly after releasing the bad update and immediately started working on a fix. The fix was released about 45 minutes after the problematic update and has version number 110411-2. Anyone who still has this problem is kindly asked to manually update the definitions to the latest version, e.g. by right-clicking the avast taskbar icon (the orange (a) ball), and selecting Update -> Engine and Virus Definitions.
We sincerely apologize for the inconvenience. As this typically only affected remote sites (and not local files), simply updating to the latest definitions should completely solve the issue (no local files have been quarantined).” – Avast blog said.
This is not an ordinary virus and not all anti-virus programs can catch it. When this virus gets into the computer it can not be stopped.
It a new bread of virus called malware. This malware controlled by a “cyber brain,” it gets into your computer, sets up a an environment inside of your PC, and then starts stealing your most important information.
“Even the safest surfers can be subjected to this sick scheme. One minute you’re minding your own business, the next you get a message that your computer is infected, and if you don’t pay $59.99 for what’s supposed to be Microsoft anti-virus, your computer stops working. But as one local couple found out, paying that fee doesn’t fix anything, in fact it makes matters worse.”

RAGUE, Czech Republic – While industry testing shows that avast! Free version 5.0 handily beats most paid-for antivirus products, AVAST Software is pushing the envelope even further with the new avast! 6.0 – launching today.
“With our new avast! 6.0 Free Antivirus, we’ve added advanced capabilities that aren’t in any mainstream AV product. Once again, we are providing a free antivirus that often exceeds the protection offered by other paid-for products,” said Vince Steckler, CEO of AVAST Software. “In these tight economic times, there is no reason for people to keep paying for the overpriced AV that they have on their computers.”
There are six good reasons why computer users should remove antivirus products such as Norton or McAfee and install the new avast! Free Antivirus 6.0.
Based on a survey conducted by Barracuda Networks, spam level was down by about 50% in the second half of 2010. However the there was a 55% rapid increase in malicious software.
Barracuda Networks chief research officer Dr Paul Judge said that the shift towards search engines and social networking sites means fraudsters are now focusing on those areas of the internet.
“The research community must continue to build innovative defences and the industry must make efforts to increase the deployment rates of those defences,” Dr Judge added.

Avast Free Antivirus 6.0 gets 9.0 editor’s ranking at Cnet.com
Avast made great strides in its previous update. Version 5 set the stage for the modern, massively popular and free security suite with a new interface that ditched a quirky, late-’90s jukebox style for a more polished look. Easier to navigate, it also became easier to add new features.
Make no mistake, Avast 6 adds features both big and small. Some that had previously only been available to paid upgrade users are now free for all versions and newer features have been seamlessly added to the interface experience. If you’re familiar with Avast 5, upgrading to Avast 6 won’t be that big of a leap.
