System SpeedUp is a potentially unwanted program which, at first sight, may appear as a useful free program. Some PC users may find it beneficial; however, in truth, it is not free as it may state to be. The official download page of System SpeedUp may be tricky because it has a button that says 'Free Download'. If the PC user wants to use it for free, he may be able only to scan a PC and detect system errors and security threats with the help of System SpeedUp. In order to remove all detected PC infections and issues, the computer user may be asked to pay $29.95 and purchase the so-called full version of System SpeedUp. System SpeedUp may show fake pop-up warning messages notifying about found nonexistent system errors and malware threats in an attempt to scare the computer user into believing his PC is affected by various PC threats. When purchasing System SpeedUp, the PC user may be encouraged to disclose his personal information like credit card information or the postal address.
