WEBSHIELDFILTER.SYS Dangerous Rating: 5 out of 5

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 of UnHackMe.

You quickly found the rootkit and SAVED my PC!

I haven't had any problems since, and I'm extremely grateful.
