How to Detect Backdoors in Programs

By Subodh / August 20, 2011

Backdoor Trojans are very sneaky. They could be present in any number of different types of program extensions or drivers. For example these malicious objects are often attached to .ordinary .doc, .docx, .xls, or .dll files. They can even pose themselves as files of said extensions.

The presence of these very evil computer and internet viruses can destroy even your entire computer system. Before your machine crashes completely, consider having this kind of malware detected and removed immediately.

You cannot see these Trojans with the naked eye. For this purpose, you need the right software otherwise you are not likely to be able to detect these harmful, infectious objects. You should learn how to spot backdoor Trojans before they spread throughout your entire computer.

Instructions

1. If you have Windows Defender open it. The best way to find this software is to Click on “Start” and then mouse over “All Programs” and click on Windows Defender. (This program may not be installed on all computers but it should be on most newer versions of Windows.)

2. Use the Windows software to do a complete scan. The “Full Scan” feature is your best option because it provides the best defense against all virus. Backdoor Trojans can be much easier removed using the “Full Scan” feature. This setting allows for you to take care of every aspect of your system.

3. Observe the scan while running. Watch carefully to see which areas of your hard drive (or even removable drives) specifically are infected. There should be a finished log where all these infections (if any) are recorded when the scan is finished. If there is a “virus vault” or similar place where unwanted infectious objects are stored, delete them.

4. Adjust your computer privacy levels. For instance, you might want to turn on your pop-up blockers on in case you forgot to shut them off. Likewise, it is a good idea to set your browsing privacy level to a moderate level. Erase all temporary internet files and web browsing history, too. You should do this as often as possible and you are advised not to save any passwords on your computer.

5. Install virus “watch dogs” to prevent future Trojan attacks. For instance, there is a such thing as “Resident Blacklist” which indicates a list of websites that you would not want to visit. It also helps if you receive virus alerts every time you open a link or attempt to download a file. E-mail scanners can also keep you protected from future Trojan back door attacks.

6. Check your computer for problems every time you use it. This especially applies to using the computer that has an “always on” internet connection. However, it also applies to making sure your computer is virus fee every single time you use the internet. Any trusted virus scanner or spy ware detector is perfect for this task. You could also set your scanning tasks to be conducted automatically when you are not sitting at your computer.
