Avast and Simple PC OPtimizer

Hello,

Does anybody know why avast blocks Simple PC Optimizer a program to help you keep your PC free from lost links in your register and find items on your disk that can be removed.
It is since a couple of days that the Optimizer program is blocked. If I reinstall both Optimizer works untill I install avast free virusscan, that moment it says that harmfull threats are blocked before the attack has taken place, and my PCOptimizer program is lost

simple pc optimizer = rogue software
