Anti Trojan

Malware on the net continue to be a major problem. Malware infection continues to escalate and undergo changes and as a result, many anti Trojan products have either been unable to keep with these developments or have altogether left the Trojan race. Trojan horses are malware programs or scripts that seem to perform a desirable function but actually compromise a systems security and allow a remote user access to the system. Though not self-replicating like worms and viruses, Trojan horses are malware since they allow hackers to remotely access a target system and either install malicious software and perform illegal operations or access, delete, download, upload or modify files. Trojans can also be used by hackers to view the users screen and either steals passwords or credit card information.

Faced with the above threats, early forms of anti Trojan software have now been replaced with more advanced malware protection applications. Today, virtually all anti-virus programs incorporate an anti Trojan component that is used to detect and delete Trojan horses. In extreme cases, the anti virus software may fail to detect the presence of a Trojan horse. In fact, almost all anti virus programs have at one time or another failed to detect the presence of a Trojan and passed it as genuine application. In such cases, it may be necessary to install an additional protection wall in form of an anti Trojan firewall. Since most hackers use port scanner software to detect the presence of a Trojan on your computer system, an anti Trojan needs to scan these ports and detect opened ports. Once it has been done, it will need to see what programs have opened these ports and if there is communication with the outside world. It will then block the ports, identify the culprit program and either recommend action to the user or simply delete the program from the system.

In most cases, the installation of a Trojan horse will come in form of a software download that is part of a software application downloaded from a file sharing network, email attachment or as an application exploit. Some hackers will also employ social engineering tactics and convince a user to installsoftware for their own use. Some websites also contain executable content and runs automatically upon entry. In all of these cases, an anti Trojan application will detect that a software application has been installed and would like to open certain ports for communication. In such a situation you will either have to allow communication to take place or block it.

To ensure that you are protected from Trojans, always update your anti-virus software, have your firewall up and running at all times, and if possible, use a third-party anti Trojan detector. This type of security will be hard to crack even for an experienced hacker.
