Even though this program is slightly different from the rogues that poise as antivirus programs, File Integrity Checker follows the same scheme in a way that the only thing it was is your money.

This fake defragmenter has quite a few tricks behind its sleeve, and a lot of users fall for it, because once installed it performs a fake system scan and then File Integrity Checker lashes out at your overall system security, saying that there are a lot of errors that it must attend to, and if you want your system fixed, you have to purchase the full version of File Integrity Checker.
