Just out of curiosity I went to this site to see what scam they were running. Most of these sites that run ads on tv are scammers in some form. So I started to run their "free diagnosis" tool which is a file you download and install on your machine. Well, Comodo went nuts. First comodo said there was a virus, then found malware. Nope. Ain't gonna do this puppy. As I'm sure that in order to really clean my registry, they will then ask you to pay a nice tidy sum for doing so. Along with telling you certain things that don't really exist on your machine. If you want to do it right and free, my old favorite that hasn't failed yet is toniart's EasyCleaner: [URL]http://personal.inet.fi/business/toniarts/ecleane.htm[/URL] Toni was a mere child of 14 when he wrote this program. Because his program became so popular, the people who owned his domain name hijacked it and tried to sell the free program.
