all right – i use spybot s&d to clean my computer, but i also use registry patrol to keep my registry intact, mainly because it saves backups if something goes wrong. i updated and scanned today and spybot identified registry patrol as malware – it said it disguised itself as a registry cleaner and labeled small problems as high risk. it's never been identified before, and other people using it don't seem to have this problem. is it malware? i removed it just in case, but if it's not, i can restore it.

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

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!

I'm going to fix my registry but don't know which Registry cleaner is better to choose.

I heard that if you download an antivirus program and another antivirus program while the old anitvirus program is still installed, your computer would be all messed up and glitchy. Right Now I have Avira, but Avira doesn't fix the RUNDLL Error, and I look at yahoo answer, nothing work, and youtube too.

So if I download a Registry Cleaner and installed it while Avira is installed, would my computer be messed up? What happen if I download a spyware, malware, registry cleaner, and an antivirus program? What would happen with my computer with all these programs? Since Avira doesn't protect spyware, malware, and doesn't do a registry cleaner.
What would happen if I download with anything in any particular order.
