>I don't know about AVG. I use a Panda and every time I open an infected message (no metter when I received it) It removes the Virus. There is a trial version of Panda at http://www.pandasoftware.com

I'm sorry Borislav, you are missing the point. Already existing email. Those already contained in a PST file. Not incoming, but already in the folders. Ones already read. Not new. I'm rebuilding a PC and I think there's a virus in one or more of the already existing messages. I need to clean them up before I reinstall the PST file to the PC. Not incoming or outgoing. Already existing.
