Spysweeper works pretty well. I have had it installed for 2 months and it blocked 180 threats already. When I just replaced my hard drive my computer ran fine and was decently fast but after some time I noticed that it was slowing down again, probably because of spyware. I regularly use Ad-Aware, Spy Bot, and I have McAfee antivirus program installed on my computer. I didn’t expect this program to get rid of anything that these other three could not. To my surprise it did just that however, it always finds stuff that the other three miss. Ever since I installed it I have noticed a very significant increase in performance of my computer. Programs open faster now and everything loads faster. I have also found it to be pretty easy to use and update. I also like that after every scan Spy Sweeper shows you a list of all the threats and shows you the level of threat. I have found that it slows down my computer a little bit though, but mine is old and definitely due for an update. Overall I was surprised that this program does a very good job doing what it is supposed to do and I would definitely recommend it to anyone that has spyware problems that affect your computers’ performance.
