hi matthan,
disable your system restore to flush out the malware thats in your restore folder, get your latest virus defs, reboot your computer into safe mode, scan with your anti-virus, adaware, spybot, and if you have one, your anti-trojan. if you don't have one go to www.thepublicworks.com, link to Ants free anti-trojan, get the latest defs.
in safe mode, delete all files that they come up with. clean your cache, temp files, cookie and history folder, and your recycle bin. reboot into normal mode, and re enable your system restore.
all the best,
murve
