%windir%\windowsbackup.exe
Jeff's Story:
My PC had gotten a bad rootkit that my ISP antivirus software (powered by McAfee) could not detect, nor could fix.
I sought a solution on the Internet and discovered your product and tried out the trial.
You quickly found the rootkit and SAVED my PC!
I haven't had any problems since, and I'm extremely grateful.
