I tried to research this product but the many fake reviews and set ups designed to distract you from ordinary, actual users allowed me to give up and go with the credit card before I should have. I'm now buying a new computer as this download made impossible the practical use of one p.c. and one laptop that I had wanted to spiff up. I'm no techie but I'm amazed I paid for something that in quick order screwed up the basic use of my machines. I'm sure the lawyers for FixCleaner would just say " all you have to do is go to these various sites, enter complicated infomation and download new editions of stuff and you"ll be all fixed up" BUT whose got time for lawyers and their technical helpers?. The point was to speed things up and the result is back up and slow down.
