Microsoft's Windows Vista has undergone a series of security tests against the top malware threats as reported by Sophos on November 30. The results, according to Jim Allchin, were a success. A clean install of Windows Vista was immune to all ten of the malware threats. However, third-party email applications, including Microsoft's Outlook, did not fare so well. Vista protected the user against running executables of known malware threats eight out of ten times. The two threats that evaded Vista's barriers are known as Bagle-Zip and Mydoom-O. Microsoft said that because the executables were found in .zip attachments, Windows Vista was unable to alert the user they had executed a malware threat. On the other hand, Windows Mail, which is available with Vista, blocked all .zip attachments.
