The problem with all of these security and spyware programmes is the amount they slow down your pc. I've got virus checkers, bot detectors, anti spyware, just about everything going installed on my machine and when you take into account the performance needed to run all of these, I dont think PC's are actually any quicker now than they were 10 yrs ago when all I had was a basic version of McAfee or Norton
Someone recommended a key stroke blocking prog the other day, I installed it, but it kept causing IE to crash if I had 2 webpages open. I've uninstalled it now and everything is fine again
