Backdoor.Litmus

Backdoor.Litmus is a backdoor Trojan horse that can give a hacker access to the computer. Like many other backdoor Trojans, Backdoor.Litmus is controlled by the hacker using IRC channels.



Possible system changes
If the Trojan was run and a hacker executed files on the computer, it may be difficult to determine exactly what was done, even after the Trojan was removed. If you are familiar with your operating system and how to use system-repair or system-checking tools, we suggest that you fully check the system for any of these modifications and undo them. Otherwise, consider reinstalling the Windows operating system.
