Trojan Horse Virus

A Trojan Horse virus is a common yet difficult to remove computer threat. This is a type of virus that attempts to make the user think it is a beneficial application.

A Trojan virus works by hiding within a set of seemingly useful software programs. Once executed or installed in the system, this type of virus will start infecting other files in the computer.

A Trojan virus can usually steal important information from the user’s computer. It then sends this information to Internet servers designated by the developer of the virus.

The developer then gains a level of control over the computer through the Trojan virus. The user may notice that the infected computer has become very slow while this takes place, and unexpected windows may pop up without any activity from the user. Later on, this results in a computer crash.

A Trojan virus can spread in a number of ways. The most common means of infection is through e-mail attachments. The developer of the virus frequently uses various spamming techniques for distributing the virus to unsuspecting users.

These e-mails contain attachments. Once the user opens the attachment, the Trojan virus immediately infects the system and performs the tasks mentioned above.

Malware developers can also spread their Trojan viruses via chat software such as Yahoo Messenger and Skype. Another way of spreading this virus is through sending copies of itself to the people in the address book of a computer already infected by the virus.

The best way to prevent a Trojan virus from entering and infecting your computer is to never open e-mail attachments or files sent by unknown senders. Not all files we receive, even from supposedly safe sources, are guaranteed to be virus-free. A sure way of protecting your PC against malicious programs is to install and update an antivirus program.
