I am thinking of buying or downloading free the best registry cleaner and I want good opinions before I do.

I don’t know much about it but I hear it can help a bit. Thanks in advance.

I have the following free programs in my PC: Malwarebytes Anti-Malware, Comodo Internet Security, Wise Disk Cleaner 4, Wise Registry Cleaner 4, Advance System Care Free, AVG Anti-virus and REVO Uninstaller. What software is not important and should be removed in my PC? Thank you very much!

Every virus protection program I try dosnt work out as good as i would like it too. So im wondering if there is any out there that can work for me.

My computer has slowed down for a long time. I've scanned the PC concerning viruses, looked through the registry, but wasn't success. I think the main problem is in litter registry and want to clean it by myself.
