How I can stop viruses or worms, such as Bagle.F, spreading in password protected ZIP files with F-Secure Anti-Virus for Microsoft Exchange?
This applies to F-Secure Anti-Virus for Microsoft Exchange versions 6.00 and above on all Windows server platforms when used together with Microsoft Exchange 5.5, 2000 or 2003 server. Since it is impossible to scan inside the password protected ZIP files, regular e-mail virus scanner is not able to detect the infections. However, F-Secure Anti-Virus Mail Server and Gateway products can be configured to stop password protected archive files regardless the content of the archive. In environments managed through F-Secure Policy Manager, change the F-Secure Content Scanner Server/Settings/Virus Scanning/Suspect Password Protected Archives setting to “Treat as Unsafe.” You must have the archive scanning enabled to be able to use this setting. Once you’ve changed the setting, you must distribute the policies to take the setting into use. In the locally managed environments, select F-Secure Content Scanner Server from the F-Secure Settings And Statistics and go to the Scanning/Advanced page.
