AV-Comparatives has posted its May results for popular AV-applications, and Microsoft’s MSE does surprisingly well.
But anti-malware testing is not an exact science — it’s more of a guideline on the current state of AV products.
AV Update: May results for popular products
Long-time Windows Secrets readers will know that AV-Comparatives (site) is one of the leading independent anti-malware testing organizations. We’ve discussed its published results numerous times in past newsletters.
The company currently uses 368 “test cases” of malicious URLs found “in the wild,” and runs its evaluations February through May and July through October. The most recent tests (PDF) include 19 anti-malware products from many of the top publishers.
During the testing periods, AV-Comparatives publishes monthly snapshots of the test results. May’s results had one surprise: the often maligned Microsoft Security Essentials (MSE) had significantly better malware-blocking scores. In the February, March, and April reports, MSE consistently produced the poorest scores for blocking malicious URLs.
MSE’s worst showing was in April, blocking just 90.8 percent of the malicious sites. But in May, its score jumped up to 97.7 percent — better than McAfee, Fortinet FortiClient (site), and Quick Heal (site).
