I'd not use it - I tried it and it totally messed up my computer to the point of not being able to get into any site - it removed all my cookies - now I'm battling with the cookies issue on every site I get into but at least I'm in! I need to take my computer in and get it fixed; I'm at the end of my rope to fix it myself; DON'T USE IT! It may have worked for some, but i'd say, You WERE Lucky!
