I purchased this software for two of my machines. It removed spyware that other software never saw.
However, it slowed down my Athlon 3200 a bit but on my Pentium 1.6GHz laptop, with 512MB RAM, it slowed it down to a crawl. Once I removed it, the laptop, resumed normal speed.
I think the software is great but I would not use it on an older machine. Too much of a resource hog.
