It appears that the latest update to Computer Associates "eTrust" anti-virus tool marks a number of Windows system files, including files that are part of eTrust itself, as malware rendering the system inoperable. Please use care in applying the update. It was released on Wednesday, Serial # 33.3.7051 . If you already have it installed and are experiencing problems: Doesn't look like there is a simple solution. If you have it installed but things are fine so far: Maybe consider turning off "on access scanning" until the next update is released (which probably has already happened)
