In my humble opinion, I think that System Mechanic is great software. It cleans up yo tracks and has many other useful options. Since I purchased it I have had no problems with junk on my computer. It's spyware program kind of blows but all the other options are very helpful. It includes a RAM scrubber, track cleaner, Defragmentor, task scheduler etc. It was recommended to me by my Cyber mentor and he is right 99% of the time. Hard to get a hold of though. You should check it out, it is free to try for 30 days, then you can buy it, or if you know how to crack it's yours. I wouldn't suggest that though. It is worth the 30 bucks. For spyware I would recommend Webroots Spysweeper, or Ad-Aware 6 Professional. I heard Spyware Blaster is good too. I guess if you are really savvy you could get rid of it all yourself, but I am not that smart unfortunately. Hope that helps.
