Windows 7 is a valuable upgrade delivering an awesome new user interface, but don't expect any major improvements in security.
Anti-virus software vendor Sophos tested Windows 7's built-in anti-virus capabilities by feeding a clean system 10 pieces of the newest malware. Eight out of the 10 samples ran successfully, claims Sophos.
"Unfortunately, despite Microsoft's claims, Windows 7 disappointed just like earlier versions of Windows," says Chester Wisniewski, a senior security advisor at Sophos, in a blog post. "The good news is that, of the freshest 10 samples that arrived, 2 would not operate correctly under Windows 7."
