A Trojan is a malicious program or spyware that flaunts a harmless appearance but one that is quite harmful in reality to your computer. Just like anti virus software, there are anti Trojan software available in the market. Trojan is different from computer viruses. They belong to the class of bots and worms. One of the best ways to remove these trouble-making programs is to format the computer drive on which they reside after saving the vital data stored in that drive on back up drives. But there are other methods of removing the virus.

In the first step, the Trojan has to be detected. There are certain symptoms that are exhibited by your PC when it is infected with Trojans. A Trojan behaves in the same way a virus does. Your computer starts acting ‘funny’ or unusual. For example, your system may go on a hang very frequently or the response may be too slow. A software security system like a firewall can detect some strange network traffic directed toward your computer. Even you can detect some automatic communication taking place in the form of some abnormal popups forcing themselves on your screen. These are just generalized symptoms and they differ from one variety to another variety of the computer pathogen.

If you can access the registry you will find that that it has the names of some new and strange executable files. This is the point where you should start with the protection operations of your PC. The first thing that you should do is to use special system files and tools to gather detailed information about the malicious program codes. Along with a scan for Trojans you can also do a quick virus scan with some of the best anti virus programs available with you. Once it gets established that there are some unusual files on the computer, the first thing that has to be done is to detect the path or the command line of the files under suspicion.

You can go through the anti virus software reviews online or in some good PC-related magazines or websites to get information about the filenames and extensions of the files that are of dubious credentials. Removing the Trojans manually may turn out to be a painful experience. A good antivirus software review will give you correct information about the sources and nature of action of the malicious software. Many times the files that you suspect turn out to be harmless applications, so you should be careful in getting convinced about their identities. The process information is of vital importance as it allows you to track your virus and also know what program codes it uses, i.e., the handles and DLLs that it uses. You can also get information of the files that the harmful code affected and cleanse them with a good anti-Trojan program.
