DTR Description

DTR is a dangerous backdoor that gives the remote attacker full unauthorized access to a compromised PC. DTR allows the intruder to manipulate files, modify essential computer settings, control certain hardware devices, restart or turn off a PC. The backdoor can also log all user keystrokes, collect important information about the computer and transfer gathered data to the attacker. DTR secretly runs on every Windows startup.

How can I get rid of DTR?

The most common spyware removal tactic is to uninstall DTR by using the "Add/Remove Programs" utility. However, as there may still be hidden DTR files, it's possible that DTR will reappear after reboot. Follow the DTR detection and removal methods below.
