See the last link in my signature. Have you tried System Restore to before all this started? It can be initiated from Safe Mode if necessary.
The next step would probably be to post a Hijackthis log on one of the specialist forums suggested lower down that link.
It's a fact of life unfortunately that antivirus applications have a hard time detecting and/or cleaning certain things. That's where specialist tools come in.
Edit: meanwhile that file will have been submitted to McAfee for analysis assuming you didn't run GetSusp in Offline Mode.
Oh when You ran getsusp did you add your email to the preferences that way Mcafee will keep you informed what they find (hopefully)
do you have the log file still from getsusp that you can upload, I will take a quick look and see if I can help.
Just on that, who or what lead you to belive you a virus called "scour", reason I ask is that sometimes the free malware tools can false detect items and mislead you
I found this, it seems to be a unwanted program,
however it looks like it was dropped with a third party app, they are sneaky little ......., they tie you in in the license and tell you its going to install, we never read these things, anyway that's why McAfee doesn't clean it, due to legal issues. Let me know if this helps
Sir Ex_Brit, I am here. Wildfire at your service. GetSusp found something, a file, that is password protected. I didn't put it there and I can't get rid of it. I've tried Malwarebytes, Stinger, regular McAfee Total Protection, and Super-AntiSpyware. Get Susp found it and I attached the results to my previous email. You said you could merge the threads. If you can't I can repost it here. Have to be away and take care of feeding duties. Be back in about an hour. This is such a wonderful community where people are so willing to help!
