You also need to use Lavasoft Ad-Aware SE Professional edition it will comprehensively scan your memory, registry, hard, removable and optical drives for known Data-mining, aggressive advertising, Parasites, Scumware, selected Keyloggers, selected traditional Trojans, Dialers, Malware, Browser hijackers, and tracking components.The cool thing about Ad-aware is that once you buy it it updates for free.
