| Any user of a computer, at some time upon their computer having a tiny problem, has thought about if that could be the result of a virus. Or maybe your virus protection program has flashed something on the screen, thinking it has found something it doesn't like. Well, inevitably, this will happen and you will be confronted with a type of Trojan virus normally referred to as a backdoor Trojan.
Backdoor Trojan viruses usually look like one type of file but are in reality something else entirely, performing malicious actions on your PC. The virus can create a backdoor on your PC. A backdoor allows the REALLY malicious acts to be performed. These can be anything from installing something on your PC to just hiding while watching until it suspects something is important. Then it dashes into action, transferring that information to the computer it was instructed to transmit to. This is how your personal data can be copied, and you will have no clue it's ever taken place. In extreme circumstances, a backdoor Trojan virus can provide another PC sufficient access to permit the infected computer to be commanded and used for who knows what tasks. These Viruses and Trojans will have names. However, the names are sometimes not really the best thing to know. What is extremely helpful is the name of the file or files that contain the code that the viruses use. An adequate virus virus scanner will provide the file names. Without formatting your hard drive, nothing can guarantee you have eradicatedthe virus. But, as was talked about above, an excellent virus scanner can help you to a large extent. At times, the duty still falls on the shoulders of the user to help and oversee what the virus scanner wants to do or what files and processes it might want to delete. There are times when the virus protection program tells the user what operations need to be performed. This is where more information can help you understand. It can tell you to search for files on your hard drive. That seems to be really easy, but when searching for Trojan virus files, it's a lot harder than it may appear. A misleading thing most Trojans and viruses do is utilize file names that are has almost the same name as files in the operating system or popular applications on your computer. This makes it even more difficult to try to find the file your searching for. For instance, maybe just the extension for the file has been changed. The following is a list of files that are utilized by some of the most well known Backdoor Trojans and viruses. Absr.exe - Used by the Backdoor.Autoupder Trojan. Desktop.arx - Is a part of the Backdoor.SdBot.md Trojan and the FFIsearch Spyware. Netlib.exe - Used by the Crater-A Trojan/Worm backdoor Trojan virus. Regscan.exe - Placed on the hard drive by Trojan.W32.Rbot backdoor Trojan virus. Sksdll.dll - Known as the Backdoor.Haxdoor.G Trojan virus. Svzhost.exe - Usually has backdoor Trojan functionality. Winupdates.exe - Used by the Robot Worm IRC backdoor Trojan virus. There are many more files and processes than those shown above that are known as backdoor Trojans. You may not have any of these Trojans running on your computer, but you may have some others. Several websites can provide additional information on backdoor Trojans. If you would like more information about any of these viruses, just enter its name in a search engine and follow some of the results that are returned. Sometimes when you view the Windows Task Manager, and look at the Process tab you will see a process that might be doing an awful lot of work, but you don't have anything really happening on the computer. All that work from the process might be going on behind the scenes and being done by a backdoor Trojan virus. To get a clue on what could be executing right under your nose, use a search engine and hunt for the process or file by entering its name. There is quite a bit of information these days, and that information can be quite helpful for eradicating a backdoor Trojan virus. |
