When I used to work as a PC Tech back in 2006-2007, I used a combination of Spybot - Search & Destroy, Ad-Aware, Spywareblaster, and CCleaner to keep my system clean.
I'm not as familiar with what technicians are using now to prevent malware, so I'd like to hear from the professionals among us: What do you use to keep your Windows-based systems clean?
