What Are Trojans?

There is a lot of virus jargon thrown around: Rootkits, worms, trojans, etc. But what do these words mean? How dangerous are they? And how do you go about solving them? In this post, we'll take a quick look at Trojans.

What is a Trojan?
A Trojan is a type of program that hides its identity behind something more useful. There are prominently two types of Trojans we see today. The stand-alone, and the modified. The stand-alone is a program that claims to be a tool, yet in reality, is a program that is used to steal personal information, and makes your computer a zombie to the hacker. However, this type of Trojan relies on a good deal of social engineering and code difficulty as to not alert the user to it running.

The other type, a modified program with the malicious code inside can take over a computer without the user even knowing anything was wrong. This would be like opening a program and allowing the code to execute in the background, highjacking all of your data.

What Do They Do?
A Trojan is different from a virus. A virus makes copies of itself, and manipulates the computer they reside on. A Trojan is more of a form of spyware. It monitors the computer for personal information which it steals to be traded on the black market.

Other functions of Trojans include:
  1. Download other maleware
  2. Create a "back-door" into your computer allowing hackers to infiltrate your computer
  3. Record what you type, usernames, passwords, credit cards, emails, and any other information that may be personal or vital that the hacker can use.
 Some Trojan names are:
  • SpeedRunner.exe
  • Srdshd.exe
  • GetModule36.exe
  • Gy.exe
  • Bkha.exe
  • Aspimgr.exe
  • Cvsdfw.exe
  • Spgxwd.exe
If you think you have a Trojan Horse installed somewhere on your computer, it is best to get it fixed immediately. The malicious code these programs deliver can be very severe and cost you a good deal of money. Monitor your processes and what it is that you open. Make sure to have updated anti-virus software, as well as a decent firewall in place. Not all anti-virus software will catch these problems.
