Dmitry Sokolov:

I created UnHackMe in 2006 to fix the problem that antivioruses did not fix: detecting rootkits.

Since that time I work every day to fix the issues that antiviruses cannot.

If your antivirus have not helped you solve the problem, you should try UnHackMe.

We are a small company and you can ask me directly, if you have any questions.
