By doing so, it is able to run automatically every time Windows boots up. While running in the background, this Trojan horse will try to do a series of malicious activities according to the commands received from the remote hackers. It randomly deletes some system files as well as folders, and disables certain programs or services without any permission, which causes some programs to be unable to start or the computer system to run abnormally. It also stealthily connects to certain websites and downloads other malware to the infected computer, which will put the system at great risk and greatly degrade the computer performance. Furthermore, it may create a backdoor in the system, allowing the remote hackers to access the files and data stored on the computer. Having this Trojan horse in their computers, users may end up spending much money to fix the problems caused by this Trojan horse and even encountering identify theft and data loss. It is no doubt that Trojan.ADH.2 is very dangerous and must be removed as soon as possible.
