PC Booster is a fake system optimization program. Some speak of it as a rogue antivirus, even though it deserves to be reported like a potentially unwanted program (PUP). Basically it works as a typical scam – coming to PC illegally, scanning it with every system startup, reporting fake error warnings and forcing users to buy its licensed version which is absolutely useless for fixing real computer bugs. Definitely, you don’t need such a primitive program on your PC. This guide will help you remove it from your system.
