Ok, today my Norton anti-virus told me I needed to restart to remove a threat, so I did. It says it was a "Backdoor Tidserv". I've tried Googling it, but found nothing, so please refrain from telling me to Google it/telling me Norton sucks. The file name was b3b7.tmp, and the treat name was "Backdoor.Tideserv". The infected files that were removed were: c:\programdata\microsoft\windows\drm\b3b7.tmp and c:\programdata\microsoft\windows\drm\b3b8.tmp . Any ideas on what these are/ where they came from is greatly appreciated so I can avoid them in the future. Thanks!
