What Is A Computer Virus?
All computer viruses are types of computer programs that are able to copy themselves, usually without permission or knowledge of the computer user. Although viruses are similar to worms and Trojan horses they are very different at the same time. While some viruses are programmed to damage the computer by doing damage to actual programs on the computer others are not designed to do any damage but rather work by replicating themselves and infecting others through email or instant messages, which is the way in which the computer user usually finds out about them.
Types Of Computer Viruses
There are actually quite a few different types of computer viruses that are known about, a few of the most major types being resident viruses, direct action viruses, boot viruses and macro viruses. Resident viruses are those viruses that dwell in the RAM memory and which work by overcoming and interrupting all of the operations executed by the system including corrupting files and programs that are opened and closed.
A direct action virus is one that has a main purpose of replicating and taking action when it is executed. The batch file of this virus is always located in the root directory of the hard disk. Overwrite viruses are those that are characterized by the fact that they delete the information that is contained in the files that they infect, and this renders them as being partially or even totally useless once they have been infected.
Then there are boot viruses that affect the boot sector of a floppy or hard disk, and macro viruses that infect files that are created using certain applications or certain programs that contain macros.
Computer Virus Eradication
When it comes to computer virus removal the eradication method that you are going to have to use will depend on the particular type of virus that your computer is infected with, so this is what you will have to determine first. Also make sure that you go with a name that you trust for your computer virus removal needs, such as McAfee, Norton, or Avast.
