It could be corruption. It happens even without a virus.

Try creating a blank new db.
Import all items.
Sometimes the bad objects will not transfer. Bring in the missing (bad) obj's from a valid backup.

Do you have a good antivirus? I've never seen a file created with that particular extension. From your other discussions, I would have to suggest running a good, full anti-virus scan. If you have something that can do so, do a full scan. Reboot your system into protected mode, which means a lot of things (including the internet) wont' start up. Then do your full system scan. Your "system started behaving abnormal" is suspicious.
