I have always used, and always will use Adaware and Spyware Blaster together as they do the job but to help prevent any attacks of maliscious spyware i run Previx Home Edition on my computer which keeps your computer safe... its even a zero day virus protector. Although for virus protection i use NOD32, truely the best, most effective virus guard ever created... i 'cleaned' my computer with norton and kaspersky and then installed nod32, it found a whole bundle of things including some quite serious stuff... Very impressed!
