Hello. I'm currently trying to sort out a PC which has been infected with plenty of malicious code. It started with persistent ad pop-ups from Internet Explorer, which progressed to Windows Security Alerts saying there were harmful viruses. First thing I did was fire up AD-Aware and let it scan, and deleted the few items it could find, some cookies and a backdoor. After a restart, Windows started up very slowly and the normal wallpaper changed into a black wallpaper disclaiming "Warning. Your computer has been infected with dangerous spyware". I also got a taskbar popup claiming my system had been infected, which would direct me into an ad for what I understand to be a rogue antispyware program, and my task manager at this point had been "disabled by Administrator". After this I scanned the computer with the Trial Version of Norton Antivirus, which found and apparently deleted some stuff as well. After this I started following the 8 step guide found on this site. The wallpaper has changed from the flashing warning to plain grey, and the start up is still extremely slow. I've attached the logs you request. Any help would be greatly appreciated.
