Trojan.Comrerop is a computer Trojan that attempts to mimic Windows processes to avoid detection. Many times some of the more popular processes that Trojan.Comrerop hides as are rexxdisc.exe, winlogon.exe and msnmsgr.exe. Some of these files are usually classified as being legitimate ones for popular programs such as MSN Messenger. Trojan.Comrerop will make up those files to hide its presence where it is able to run in the background. Trojan.Comrerop could cause issues if left on a PC such as allowing a remote hacker to connect to the infected system and steal data.
