Ioo

thank you very much for your quick reply.

I cannot perform the bitdefender online scan.Tried several times but when it updates the virus database and starts scanning my computer, suddenly the internet explorer window shuts down and kaspersky gives the following allert:

Process C:\system32\drwtsn32.exe tried to access Kaspersky Internet Security, but the action has been blocked by the self-defense component.No action on your part is required.

Further, the same alert comes frequently for iexplore.exe, even when the pc is idle.

I have scanned iexplore.exe and drwtsn32.exe on virusjotti.Nothing found.Don't know what to do now :(.
