I'm reading all new comments so don't hesitate to post a question about the file. If I don't have the answer perhaps another user can help you.
I have been having "Bad Request HTTP Error 400. The request is badly formed." I ran Iolo Malware Killer and it keeps finding and quarentining "C:\windows\system32\drivers\ampse.sys", but I cannot remove it through Iolo, it just comes right back. If I go into the c drive and try to rmove it from the file manually, it saya it is in use by another application and won't let me delete it. Any thoughts?
