Yesterday I was doing a clean up with Ccleaner etc and in my haste I did not take note of what I was clicking. Spybot Search and Destroy flashed up and I clicked to allow, or not allow as the case may be, to do something to, from what I can remember, 'WLON' or something similarly named. In any case, what happens now is that I fire up the computer, enter my password, the desktop briefly flashes up for a split second(no icons) and then it immediately logs off and goes to password entry again. Can't seem to get around it and don't know what to do. Any help please.
