Secunia ranked Windows Live OneCare 5th, detecting only 1,67% of the exploits tested on. The testing were a mix of three different kinds of exploits: Proof of Concept (PoC), GameOver PoC and Exploit. The test cases were separated into two groups, malicious files (.gif, .mov etc.) and malicious web pages (ActiveX and other browser vulnerabilities).
Not happy with the results Microsoft labeled the results as misleading and confusing to average consumers.
“At first glance, it would seem that this test would be very helpful to consumers to determine the best security suite in the specific scenario – although none of the suites did particularly well in this specific situation. However, Secunia's test focused only on the on-demand scanner functionality and did not take into account any of the other built-in security protections in Windows Live OneCare or other suites included in the test.”
