SpyCrush, a variant of VirusBurst, is a rogue anti-spyware program that uses deceptive tactics to trick you into purchasing their software. Once you're infected with SpyCrush, a security message similar to a Windows notification pops up saying your PC is infected with malware. This fake message is used to lure you into purchasing, downloading %26 installing their program to remove the imaginary spyware. SpyCrush program can be extremely difficult to remove manually, and will continue to try to recreate itself. SpyCrush may also download and install other software without your permission.
