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.
