This is the program I tried to install when the problem started so that I can not get into my PC

I was thinking it is a cleaner like CCleaner.

I have tried to recover my PC to old point even by starting from BIOS to DVD drive. I have also tried to reinstall windows 8 but it will not let me. Everytime it say the place with Windows is locked by a AV. I have two HDs and im thinking if only I could make the windows 8 install on the second HD I could get into my PC and perhaps delete the problems.

Thanks for trying to help out though.
