What is a Virus

A Virus is a computer software that has the main ability to replicate itself very rapidly and get attached to most of the files and programs of the host system. A virus enters the host system as some sort of file, mainly posing as zipped or as a legitimate program. A virus can do virtually no harm by itself, like its biological counterpart the true damage only occurs when the virus infects a host system. After a virus infects a computer it rapidly multiplies and invades most of the files and folders on the host system and settles in according to the instructions of its creator waiting and watching. Any sort of virus computer users encounter these days are very lethal and have immense potential to cause an extensive amount of damage to a computer.

Types of computer viruses

There are many different types of viruses with hackers adding many more each day to their arsenal. Some just slow down your system, some erase data, some monitor your activities and some make your system crash entirely and make sure you cannot recover your data.  Well here are a few common select few viruses you should know about.

Resident viruses

       This kind of virus is a permanent kind of a virus that infects and dwells in the RAM memory. From the Random Access Memory the virus will infect all of the operations executed by the system. Corrupting them it will affect programs that you open and close, copied renamed, anything that is being used will get corrupted and eventually the host system will crash.

A few examples of resident viruses include Randex, CMJ and MRKlunky

Direct action viruses

             The first and foremost objective of this type of virus is to replicate rapidly and execute its program on command. When a special criteria is met the virus will kick into action, and infect the directories and folders that it was programmed which are specified in the AUTOEXECE.BAT file path. This file will always be located in the root directory of the hard disk and executes a few commands when the computer is booted

Overwrite Viruses

             These types of viruses are those that infect files and documents and delete a part or the entire document making it partially or totally useless after they have been infected.

The only way to clear these viruses is to overwrite the files thus loosing the original content.

Examples of these pesky viruses are, Trivial.88.D ,Trj.Reboot and Way

Boot Virus

This type of virus mainly affects the boot sector of a floppy, USB drive or a hardisk. This is the most important part of the hard disk. In which information of the disk itself is stored together with a program that makes it possible to Boot the system. So you can imagine what would happen, if you got a virus there.

Examples of boot viruses include: Polyboot.B, AntiEXE, LoJo816

Macro Virus

Macro viruses mainly infect files that are created using certain applications or programs that contain a lot of macros. These so called mini-programs make it possible to automate series of operations so that they are performed as just a single action, thereby saving the  user a lot of time from having to carry them out one by one.

Examples of macro viruses: Marcet2K, Melissa.A, Relax, O97M/Y2K and Bablas.

Directory Virus

These viruses only change the main paths that indicate the location of one particular file. By just executing a program (file with the extension mainly like .EXE or .COM) which has been badly infected by a virus, you are actually running the virus program and you will never ever find out, while the original file and/or program have been previously moved by the virus.

Once infected it becomes virtually impossible to locate the original files.

Polymorphic Virus

These kind of viruses encrypt or encode themselves in a different way (using different algorithms and encryption keys) every time they infect a system.

This makes it impossible for anti-viruses to find them using string or signature searches (because they are different in each encryption) and also enables them to create a large number of copies of themselves.

Examples include: Elkern, Marburg, Satan Bug, and Tuareg.

Companion Viruses

These types are be considered to be file infector viruses like the resident or mainly direct action types. They are well known as companion viruses because once they get into the system they mainly “accompany” all most all the other files that already exist. In lay man’s terms, in order to perfectly execute their infection routines, companion viruses can wait in memory (for a very long time if necessary) until a program is run (resident viruses) or act immediately by replicating themselves (direct action viruses).

Some examples include:, Asimov.1539, Stator, Galmor554 Terrax.1069

FAT Virus

The file allocation table or FAT is the most important part of a disk that is used to connect information and is a very crucial to the normal functioning of the computer.

This type of virus attack can be especially dangerous, by preventing access to certain sections of the disk where most important files are stored. The damage caused can result in massive information losses from individual files to even entire directories.

A virus will usually either immediately execute the program when run or will remain dormant in memory awaiting for the right time to be executed so to infect maximum damage. Removing a virus will require special tools specifically designed to eradicate viruses. Certain types of virus can even re –infect most even after removal. It is highly recommended that you use anti-virus software and ensure that it is properly and promptly updated. Most anti-virus program are indispensable for all internet users.
