having an anti spy program that runs in the background to find spyware is good, but with my celeron, i dont have the proccessing power to spare to be runnin anything like that, i hate this thing, i plan to build another, with a 775 socket 3.2 ghz Pentium 4 prescott HT with 1mb of cache out of an ole HP desktop (somones givin me it free, they only use AMD) but, i do advise programs that run constantly if your computer can handle it. even with a gig of ram, my celeron d is far too weak to do much.... even when it comes to protection...
