Best free antivirus Windows 8.1

The best anti-virus protection for Windows 8.1 home users and business?  November 18, 2014 – 10:31 am

Windows 8.1When respected anti-virus testing body AV-Test.org released the results of tests it had conducted against business security products running on Windows 7 earlier this month, it caused quite a kerfuffle in the ...

Mostly from home users who hadn't read properly that it was a test of *business* anti-virus products, and that might be why their preferred home user anti-virus wasn't included in the test.

So, I'm pleased to share AV-Test.org's latest test results, where they looked at the protection, performance and usability of business *and* home user anti-virus products, running on Windows 8.1.

Products tested include solutions from AhnLab, Avast, AVG, Avira, Bitdefender, Bullguard, Comodo, ESET, F-Secure, G Data, K7 Computing, Kaspersky Lab, Intel/McAfee, Microworld, Norman, Quick Heal, Microsoft, Panda Security, SentinelOne, Seqrite, Sophos, Symantec/Norton, ThreatTrack, and Trend Micro.

Consumer anti-virus test for products running on Windows 8.1Here is the executive summary for home user anti-virus products, where Avira, Bitdefender and Kaspersky appear to have run off with top honours:

And here is the chart for business user anti-virus products, with Bitdefender and Kaspersky getting gold:

Most products appear to have performed reasonably well in the tests, with the only truly horrendous performer being Microsoft. One interesting inclusion in the business tests was SentinelOne, a so-called "next generation" security product. To its credit, SentinelOne appears to have performed well, keeping up with other better known anti-virus products:

With only one exception, the participants did not have major issues regarding false positives or scan speed/performance degration. For the first time ever a "Next Generation" security product has been included: The Endpoint Protection suite of SentinelOne. The results prove that it is able to keep up with the traditional Anti-Virus products.

AV-Test.org reported that most of the products' detected the vast majority of the unknown, zero-day malware threats thrown at them:

"The malware protection of most tools was at an acceptable to good level, on average around 98-99% of all "zero day" malware attacks were blocked."

Of course, even if a product scores 100% in AV-Test.org's tests it's worth bearing in mind that no anti-virus software is perfect - and only part of the answer to keeping your Windows computer safe and secure.
