Registry cleaners are a con. You don't need them. They either report non-existent errors or really minor abnormalities, within the registry, which don't do any harm anyway.
Don't pay. You can safely ignore all of those warnings. (If you're actually experiencing problems with your computer, post the details here and we'll tell you how to fix your problems).
Hi, everything seems OK now, it's just that it runs slow now and again, I read somewhere about doing a clean up, so I just tried that one,
Thanks for your advice.
