I currently am running KIS 6.0 and SpySweeper, some minor slowdowns of course, I am considering dropping Spysweeper (not that it doesn't work) it just seems to slow the system down a little too much, then again KIS could be slowing the system down as well. Either way if I was going to change Anti-Spyware software, which would be my best bets. I have seen people here praise (CounterSpy, Trend Micro and AVG Anti-Spyware). Which do you think would run the best with KIS 6.0 of course SpySweeper is still an option. Please don't recommend a product over another one just because it might be free. If I have to pay for something that is a better product that is fine. Also you are free to recommend other products that are not listed since I cant possible know all products that might be available. Thanks All, Billy S.
