SystemCleanerPro is a rogue antivirus application. It is a part of the WinSpywareProtect family and will run at system startup. It will popup many warnings about your computers security (or lack thereof). It will scan your system and claim there are viruses and it will repeatedly nag you about purchasing their software. They will claim that the problems they have identified with your system cannot be repaired unless you purchase their software. This should raise a red flag. Of course you should also consider this a scam when you realize that you are not sure how you came to have this software on your system. Read on for how to remove SystemCleanerPro.
