Backdoor.Hackersdoor is a computer infection that violates system security. This backdoor Trojan was first detected in November 2011. The way Backdoor.Hackersdoor works is rather simply - the malware installs an undesirable driver file that allows other malicious applications into the target computer. This backdoor is not called "Hackersdoor" for nothing - the Trojan opens a backdoor and additional malware compromises the computer even further.

Backdoor.Hackersdoor is able to infect Windows XP, Windows Vista, Windows Server 2003 and other systems. Usually this Trojan is delivered via a drive-by download or spam email messages. When it gets installed, Backdoor.Hackersdoor looks like a .dll file. Files associated with the Trojan include file.dll, atkctrs.dll and kernel.dll. During the installation the Trojan creates new subkeys in the registry that forces the system to load Backdoor.Hackersdoor as a system driver.

Once the Trojan is up and running it opens the system backdoor and then waits for particular network traffic. Backdoor.Hackersdoor can perform a list of actions depending on what the attacker wants it to do. For example, it can take a screenshot of the infected computer or make it shut down. Even though it is a backdoor, the Trojan is also capable of downloading additional malware onto the computer. Backdoor.Hackersdoor is not a stranger to stealing files and passwords as well. After having stolen sensitive information from the infected system the Trojan uploads the files to a remote server.

To remove Backdoor.Hackersdoor from your computer you need to stop the Trojan's processes and then delete its files and registry subkeys. However, if you are not sure you can handle working with Registry Editor, acquire an antimalware program and erase Backdoor.Hackersdoor automatically. The program will also check your system for other possible infections.
