Backdoor Trojan Viruses Finding Then In Computer

By: Robert Thomson

Any PC user, at some time when their computer has a tiny glitch, has wondered if the glitch could be caused by a virus. Or maybe your virus protection program has set off all kinds of alarms, thinking it has discovered something it was watching for. Well, eventually, this will happen and your going to be face to face with a type of Trojan virus normally called a backdoor Trojan.

Backdoor Trojan viruses usually resemble one type of file but are in reality something else, performing malicious acts on your computer. The virus can create a backdoor into your PC. This backdoor allows the really big malicious acts to be performed. These can be from downloading something to your PC to simply hiding while looking at things until it suspects something is important. Then the virus vaults into action, sending that information to a computer it has been programmed to send to. This is one method your personal data can be taken, and you will have no idea it's ever happened. In extreme circumstances, a backdoor Trojan virus can give another PC sufficient permission to permit the infected computer to be run and used for virtually any tasks.

The Viruses and Trojans most likely will have names. But, the names are typically not particularly the most useful thing to know. What is really helpful is the file names that contain the code that runs the viruses. An excellent virus virus detection program will give you the file names.

Without formatting the computer's hard drive, there is practically nothing you can do to guarantee you get rid of a virus. However, as was talked about above, a good virus scanner can assist you to a large extent. Sometimes, the burden still falls on the shoulders of the user to help and watch over what the virus scanner wants to do or what files and processes it could want to delete. There are times when the program will tell the user what to do. This is when more information can really help.

It can tell you to look for files on your hard drive. It seems to be really simple, however when looking for Trojan virus files, it's a lot more difficult than it sounds. One trick virtually all Trojans and viruses do is utilize a file name that is very similar to files in your operating system or many popular applications on your PC. It makes it greatly more difficult and confusing trying to locate the correct file. For instance, maybe just the extension on the file has been changed. The list that follows is files and processes that are utilized by some of the most well known Trojans and viruses.

If you would like more information about any of these viruses, just enter the file or process name in a search engine and follow some of the results that are provided.

Trojan virus.
