Symantec offers a free 90-day evaluation copy of Altiris Deployment Solution to help administrators quickly repair PCs rendered inoperable by the McAfee virus definition distributed
On April 21, 2010, McAfee released a virus signature that incorrectly identified a core Windows operating system file called SVCHOST.EXE as the threat W32.Wecorl.a. When McAfee’s products incorrectly detect SVCHOST.EXE as malware, the file may be deleted from the computer or quarantined, but without access to this critical operating system file, Windows fails to load properly and can cause significant system instability. For example, when this occurs Windows may shut down the computer and when the user attempts to re-start, the machine may become completely inoperable.
At this time, we believe this “false positive” primarily affects enterprise McAfee antivirus products running on Windows XP Service Pack 3, including international versions of Windows XP.
