Different types of Virus and their effect's.


Different Types of Computer Viruses There are Different Types of Computer Viruses could be classified in (origin, techniques, types of files they infect, where they hide, the kind of damage they cause, the type of operating system or platform they attack) etc. Let us have a look at them…

Computer Virus is a kind of malicious software written intentionally to enter a computer without the user’s permission or knowledge, with an ability to replicate itself, thus continuing to spread. Some viruses do little but replicate others can cause severe harm or adversely effect program and performance of the system. A virus should never be assumed harmless and left on a system. Most common types of viruses are mentioned below:

fb7fa0a.jpg

Resident Viruses
This type of virus is a permanent which dwells in the RAM memory. From there it can overcome and interrupt all of the operations executed by the system: corrupting files and programs that are opened, closed, copied, renamed etc.

Examples include: Randex, CMJ, Meve, and MrKlunky.

Direct Action Viruses
The main purpose of this virus is to replicate and take action when it is executed. When a specific condition is met, the virus will go into action and infect files in the directory or folder that it is in and in directories that are specified in the AUTOEXEC.BAT file PATH. This batch file is always located in the root directory of the hard disk and carries out certain operations when the computer is booted.

Overwrite Viruses
Virus of this kind is characterized by the fact that it deletes the information contained in the files that it infects, rendering them partially or totally useless once they have been infected.

The only way to clean a file infected by an overwrite virus is to delete the file completely, thus losing the original content.

Examples of this virus include: Way, Trj.Reboot, Trivial.88.D.

Boot Virus
This type of virus affects the boot sector of a floppy or hard disk. This is a crucial part of a disk, in which information on the disk itself is stored together with a program that makes it possible to boot (start) the computer from the disk.

The best way of avoiding boot viruses is to ensure that floppy disks are write-protected and never start your computer with an unknown floppy disk in the disk drive.

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

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

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

Directory Virus
Directory viruses change the paths that indicate the location of a file. By executing a program (file with the extension .EXE or .COM) which has been infected by a virus, you are unknowingly running the virus program, while the original file and program have been previously moved by the virus.

Once infected it becomes impossible to locate the original files.

Polymorphic Virus
Polymorphic 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.

File Infectors
This type of virus infects programs or executable files (files with an .EXE or .COM extension). When one of these programs is run, directly or indirectly, the virus is activated, producing the damaging effects it is programmed to carry out. The majority of existing viruses belong to this category, and can be classified depending on the actions that they carry out.

Companion Viruses
Companion viruses can be considered file infector viruses like resident or direct action types. They are known as companion viruses because once they get into the system they "accompany" the other files that already exist. In other words, in order to carry out their infection routines, companion viruses can wait in memory until a program is run (resident viruses) or act immediately by making copies of themselves (direct action viruses).

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

FAT Virus
The file allocation table or FAT is the part of a disk used to connect information and is a vital part of 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 important files are stored. Damage caused can result in information losses from individual files or even entire directories.

Worms
A worm is a program very similar to a virus; it has the ability to self-replicate, and can lead to negative effects on your system and most importantly they are detected and eliminated by antiviruses.

Examples of worms include: PSWBugbear.B, Lovgate.F, Trile.C, Sobig.D, Mapson.

Trojans or Trojan Horses
Another unsavory breed of malicious code are Trojans or Trojan horses, which unlike viruses do not reproduce by infecting other files, nor do they self-replicate like worms.

Logic Bombs
They are not considered viruses because they do not replicate. They are not even programs in their own right but rather camouflaged segments of other programs.

Their objective is to destroy data on the computer once certain conditions have been met. Logic bombs go undetected until launched, and the results can be destructive.

What to do,computer is full of viruses wont let me in anywhere,system locked up,


In cases like this, you have no alternative but to format the hard disk and install Windows again.
You need your Windows installation CD and product installation code. After installing Windows and the Service packs, plus the computer's device drivers, then activate Windows, and install your programs.

You are infected with a Trojan or Malware. The pop-ups are bogus.. You are only infected with the product they are trying to sell you. What is the name of the Virus Protection they are trying to sell you? First thing to do is restart your computer in Safe Mode and run all your security scans. See it they find the culprit.If not post back,

Malware Part 1: Viruses, Trojans, Worms, Spyware, Adware


Malwares or Malicious softwares are programs that are made intending to sabotage and destroy your computer or penetrate, spy and steal your information on your computer. These Malicious Software could be categorized into 5 major groups Viruses, Trojans, Worms, Spyware and Adware. What, are the differences between these 5 types?

Viruses are programs that act like biological viruses. They replicate or make a copy of themselves in another host. Using an infected host, like USB Flash disks or drives, viruses infect your computer and wait until you insert another flash disc to infect. While waiting in your computer, viruses, depending on their code, could either slow down the system, mess up your file system, or even destroy your files.

Trojans are programs that do not replicate or copy themselves. Trojans are software that are made by would be hackers to spy on your computer and create what they call back doors. These programs are intentionally placed on your computer directly, where there is physical contact with the computer, or indirectly, where a copy is sent through your Email or even by an infected Flash Drive. The trojan would then be on your computer but it will neither replicate nor crawl to other computers connected to the infected computer.

Worms, on the other hand, are the ones that have the capability to crawl to any computer connected to the infected computer. Worms infect computers through the local network and even through the public networks. Worms infect others by scanning your network and infecting any computer connected to your network. Other Worms would scan your email software for email addresses and send a copy of themselves to your contacts and act like it was sent by you. Worms also have the capability to destroy your files depending on the code programmed into it. Worms also has the effect of slowing down your network speed since it would scan your network and send copies of itself. Worms eat up a lot of bandwidth in a network.

Spyware and Adware are almost the same. The difference of these two is the intent and the usage. Spyware as its name implies is used to spy your computer for any vulnerabilities. Adware on the other hand is used to constantly bug you with Advertisements. Normally known as Unwanted Pop-ups. Both, however, can infect you by websites, that without your permission, that copy or install these unwanted software into your computer. Spyware and Adware, are sometimes also considered as Trojans by other Antivirus Software since it does not replicate or crawl in the network but does damage to your computer.

Whichever type, these Malicious Software, is harmful to your computer and is a threat to your personal security. It is best to be able to early detect these software and be able to purge them out of your system. As prolonged, exposure to these Malicious Software is very damaging which could cause you to lose your data.

In Malware Part 2: Malware Detection and Removal, we will discus how to detect malware and some basic techniques in removing these Malicious Software.
