UnHackMe is a tool which you can use to complement your current antivirus; it detects and eliminates rootkits on your system.
But what is a rootkit? A rootkit is a malware, similar to a trojan, whose main feature is that it hides all of its tracks and any evidence of its activity from the user (as well as from most conventional antiviruses), opening up backdoors and allowing external intruders to access your computer with administrator privileges.
Usually, these programs are quite good at their job and are very hard to detect, which is why a program that is exclusively devoted to them, such as UnHackMe, can be of great help.
UnHackMe runs using a friendly and easy to use interface and lets you locate suspicious processes which might be working behind your back. One of the main differences of UnHackMe is that instead of analyzing processes when they are already running, it scans the system at startup and notifies you of suspicious processes which are trying to run anomalously.
