what is a trojan virus?

Question

my Norton thingy said that it couldn't remove some trojan bug,should I be worried?

Answer 1

You know the story about the Trojan Horse.

Insite the wooden horse were soldiers. The enemy was curious and transported the horse within the wall. As soon as that has the fact. the soldiers jumped out ot the horse and took over the ford.

That is what a trojan virus does. It tries to get into your computer and when it succeeds, it can do all kind of harm to your computer.

Norton is one of the worse anti virus programs at the moment. but I take it that you have a paid version. When not, you should uninstall it.

You might have to google for Uninstaller tool for norton.

In case you keep Norton, you can install some extra protection, You can use those together with Norton.

Answer 3

A trojan horse is an executable program that is designed to disrupt or hijack applications on your computer. The reason why these programs are developed are often to initiate other attacks from more advance malware such as spyware.



You need to kill the process and the dll files attached to the trojan. You need to edit the msconfig and registry to stop it from loading startup. Here is a good tutorial:

Answer 4

This article refers to a form of malware in computing terminology. For other meanings, see Trojan Horse (disambiguation)



In the context of computing and software, a Trojan horse, also known as a trojan, is a form of malware that appears to perform a desirable function but in fact performs undisclosed malicious functions that allow unauthorized access to the host machine. Therefore, a computer worm or virus may be a Trojan horse, given that open access up to intruders. The term is derived from the classical story of the Trojan Horse. This is an incomplete list, which may never be able to satisfy certain standards for completeness. You can help by expanding it.
