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.)
