2. No need to SHOUT for help. It doesn't make it happen any quicker.
3. Have you got decent virus protection?
4. When did you last do a scan?
5. Have you been visiting any torrent or pirate download sites?
Did you recently install or update your anti virus app (Avast or AVIRA)?well when it first happened my antivirus (microsoft security essentials) needed updating which i did but nothing has changed Try uninstalling MSE and see if you still get the same error. If you do, reinstall MSE. If not, try installing another AV. Either way, do not run without a resident av for longer than the test period.
