I have been reading a thread on here and another place. I have a blue background screen with a Spyware warning. I also get the little popups from windows warning that my system is infected. MS Internet Explorer Pops up and goes to several sites to download software and also goes to porn sites, pharmacy and dating sites. I do not use explorer I use Firefox. I have tried all the suggestions here. It is not a web page warning. I go into explorer and delete it or change it, it will come right back. It is listed as mywallpaper.bmp I have used Hijack this and found only one file according to a list I got. I have used Smitfraudfix option 2 which is suppose to erase the background and windows popup. It has not worked. I have used ATF Clean, CCleaner, and AVG antispyware. I have cleaned the registry and noticed that soon after I clean it, there are already new items being written to it again. I keep cleaning it for now. I hope someone has the answer, I will keep researching and if I find it I will post it here. Thank you to everyone who may help.
