Virus Removal – What Is A Trojan Horse Virus?

At some point most of us have heard the term “Trojan horse” used when describing a type of virus. But many of us know little about what a Trojan horse virus actually is.

A Trojan horse virus is effectively a file or a piece of software which appears to be legitimate and serve a purpose, but is in fact harmful and capable of damaging your PC and compromising your privacy. Trojan horse viruses are also notoriously stubborn, making the virus removal process very difficult.

A Trojan horse virus gives the author of the virus complete access to a computer system remotely over the Internet. Once installed on your PC, the author can access the program immediately and use it to perform a variety of tasks. This unbridled access also allows the hacker to easily install other forms of malware including spyware, worms and other types of viruses in your system. As well as the ability to download and install these dangerous files and programs, a Trojan horse virus can crash your system and wipe your entire hard drive causing you to lose all of your important files, photographs and media files. (Often with no way of recovering them.)

If you remember your history, you will recall that the Greeks won the Trojan war by hiding in a large hollow wooden horse in order to enter a heavily fortified Troy without knowledge. This indeed is how a Trojan gains access to your computer. Trojans get on your computer by downloading seemingly harmless programs such as games, pictures, music or movie files, but once these programs are executed, their job begins. Trojans may only do things to annoy, but they can do worse damage. Trojans can erase your disk, send your credit card numbers and passwords to a stranger or let others use your computer for illegal purposes like denial of service attacks, crippling networks for months.

What Is The Difference Between A Worm, Virus And Trojan Horse?

Tips and recommendations for protecting your PC…

Most of us don’t make a real difference between worm, virus and Trajan Horse or refer to a worm or Trajan Horse as a virus.

All of us know all are malicious programs that can cause very serious damage to PC. Exist differences among the three, and knowing those differences can help you to better protect your computer from their often damaging effects.

A computer virus is a program or piece of code that is loaded onto your computer without your knowledge and runs against your wishes. Some viruses cause only mildly annoying effects while others can damage your hardware, software or files. Almost all viruses are attached to an executable file, which means the virus may exist on your computer but it cannot infect your computer unless you run or open the malicious program. A virus cannot be spread without a human action, (such as running an infected program) to keep it going. People continue the spread of a computer virus, mostly unknowingly, by sharing infecting files or sending e-mails with viruses as attachments in the e-mail.

A worm is a program or algorithm that replicates itself. A worm has the capability to travel without any help from a person from PC to PC and have ability to replicate itself on your system, so rather than your computer sending out a single worm, it could send out hundreds or thousands of copies of itself, creating a huge devastating effect.
