Remove TR/Crypt.XPACK.Gen virus (Removal Instruction)

TR/Crypt.XPACK.Gen is the generic description from Avira of unknown trojans which are detected by its heuristic engine.
TR/Crypt.Xpack.Gen
TR/Crypt.XPACK.Gen spreads mostly via email but can also utilize auto run capabilities of removable media, or install via a drive-by infection when the user visits a compromised or malicious webpage. Once the infected binary file is installed to a machine it connects to a command and control server, and also monitors for internet activity and uploads stolen data.
While Avira will easily detect a new piece of malware by using this heuristic detection,it can have some issues while trying to remove this infection from your computer.
Because Avira used a heuristic detection technique to detect this infection,it’s recommended that you submit the detected file to virustotal.com to see if it’s really a piece of malware or just a false possitive detection from Avira before going ahead and perform the removal guide.
