I was able to revive my aging Gateway computer with this program. Not sure what exactly did it, but now it runs at a decent speed which makes me happy.
I believe this software is a scam. Certainly, their business practices are sleazy, with fake "WikiFix" articles leading to the software, and their making every conceivable effort to lead you to believe the software is 'free." It isn't. The download is free, and the "free scan" will invariably tell you that you have a zillion errors that will be fixed once you "activate" the software, a/k/a buy it for 30 bucks. Given these practices, how can anyone believe the software itself is not rubbish to the core?
