A .PST folder in Outlook 2007 keeps on going corrupt because of viruses.
The scenario happens as follows:
Outlook 2007 would be operational. Kaspersky AV will detect a virus in an incoming email (Kaspersky message box pops up), then Outlook shuts down. When you restart Outlook, it says something along the lines of "SCANPST needs to run" and at this stage Outlook will not open. When you run SCANPST it does repair the .PST file but then the next virus knocks Outlook 2007 out again.
BTW, the folder size is only about 3GB.
What do you think best course of action is here?
