How to defend computer attacks..

We all have heard the terms Virus,Worms,Trojans and Spyware not only heard but also experienced few in our PC’s in day to day life but only a few of us know the difference between them. So i thought i would illustrate with what i know to the people and this post is for folks who really need to get through the attacks from your PC’s. So to get through you need an Anti-Virus of-course but also some basic knowledge of what is what to remove it.

Virus :

A Virus is a self replicating program that attaches itself to an executable file.When the file is executed the virus automatically gets executed and enters into system memory .Once it enters into system memory it either searches for other files that can be infected or stays in the background and infect the files that are uses the virus infected program.

Worms :

Worms are very similar to that of the viruses but differ in the way that they do not bind themselves to a executable files instead to replicate themselves using the networks. These worms always targets your network. So,if you find excessive use of your network bandwidth then you may be infected by a worm.A worm do not require a user to execute any file for its execution it can work without user intervention. So this is much dangerous than that of the virus.

Trojan Horse :

A Trojan horse is harmful program which may seem harmless to the user before its installation but instead it is programmed or reverse engineered to facilitate unauthorized remote access to the computer.Trojan’s do not replicate them self rather they give access to your files to the remote computer/user who programmed the Trojan horse.The term is derived from the Greek mythology story of  Trojan horse because Trojan horses employ a form of methodology, presenting themselves as harmless, useful gifts, in order to persuade victims to install them on their computers.

Spyware :

A spyware is a program that secretly monitors and collects pieces of information.They usually run in stealth mode and cannot be detected easily. Key loggers is a great example of spyware software.There are not limited to just spying but can also send data to remote computers.

We generally consider everything that is detected by an antivirus is a virus but this is not the case.The antivirus not only provides protection against viruses but it also protects us from Trojans,Worms and Spywares.

All these can be harmful to your computer hardware and software. So always try using a Genuine Anti-Virus software,installing Anti-Virus is not only the way it is gonna help you fight for all, but also those frequent updates through which it comes to know the various attacks to defend.So do get your Anti-Virus updated frequently to make your PC virus free.
