SOFTWARE FLOGGER Microsoft might have given malware writers information about good places to hide their creations, an insecurity outfit claims.
The Vole decided it would be helpful and provide a list of file extensions and folders that probably do not need to be looked at by antivirus scans.
In a document published on its support site, Microsoft suggests that users do not need to scan some files and folders for malware as a way to improve performance in Windows 2000, XP, Vista, Windows 7, Server 2003, Server 2008 and Server 2008 R2. "These files are not at risk of infection. If you scan these files, serious performance problems may occur because of file locking," the Vole said.
However the move has ticked off some insecurity companies. They feel it is up to them to say what files people should scan.
Trend Micro said that while the list was fair enough, and there was no point wasting computer time scanning files that contain no malware, the Vole should have sat on the information. It thought that by making its list public Microsoft might have told malware writers where to put their viruses.
