What are Trojans and How To Get Rid of Them?

Trojan horses are notorious today for their use in the installation
of backdoor programs. Simply put, a Trojan horse is not a
computer virus. Unlike such malware, it does not propagate by
self-replication but relies heavily on the exploitation of an
end-user (see Social engineering). It is instead a categorical
attribute which can encompass many different forms of codes.
Therefore, a computer worm or virus may be a Trojan horse.
The term is derived from the classical story of the Trojan Horse.

A particular Trojan will disabled or hang your anti virus pro-
gramme like Norton Anti Virus. This just happened to one
of my customer's laptop and I was called to fix it. Well, jus for
a few hours of work, you may save a few hundreds of dollars.
I actually did charge the company a few hundred dollars.

You will need anti spyware/adware programmes to get rid of
Trojans. The one I recommend and tested is SuperAntiSpyware.
You may download and run the installer at the suggested link
below. The free download version is only for home user, and does
not have the same functionality as the Professional version. That
is sufficient if you perform periodic scanning. You also need an
anti-virus software.
