Full user review
"A free way to clean and fix PC errors."
This program is free, and contains lots of tools to clean and fix PC. There is a tool to fix registry errors, defrag registry, find PC errors, and much more. It also have frequent updates for free.
Some features are useless such as the security scanner. I have antivirus and anti-spyware already.
It is a must have for PCs. It is free, and can fix your PC, so why not just give it a try?
