Trojan Horse A trojan
horse is a fake program that pretends to do something
desirable but on execution trojan horse infects the
system. Trojan horse does malicious activity without the user’s
knowledge. Trojan horse is one of the most hostile types of malware you
may encounter online. Trojan horse is particularly hostile
because trojan horse can be downloaded onto your computer
without your knowledge and this trojans are used against you in
very dangerous ways. Because trojans do not call attention to

viruses), trojans can remain hidden and allow someone
to control your PC for long periods of time. Because trojans are
hard to find, trojans cannot be removed
easily.

a website that was completely unknown to you? If so, your PC may
have infected with what is called a homepage hijacker .

many to be a type of trojan horse. Typically, a hijacker will redirect
your computer to adult sites then connect you to all the related pop-up
advertising and banners. Hijackers are also difficult to remove.
Key Loggers Key logger records anything you type on
your PC keyboard. Key logger's are probably the worst type of
malware. The collect data is either stored on your computer for later
retrieval or secretly piggybacked onto e-mail messages you send
out. Can you imagine about all the information you type onto
your computer – from personal information in e-mail messages to financial
information such as credit card numbers and online banking passwords. Key
loggers can even hack into your webcam. You can use good
free spyware removal programs to remove these threats from your
