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.

I can not update my anti virus software. it shows as updated successfully but it does not repair virus, merely it detacts virus


Bro not all updated virus softwares can heal your PC Virus. Like in my PC, the best thing I did to eliminate it is to backup my files and reformat it then install a fresh copy of licensed softwares but not all time. You can also upload a virus to the internet and report it to Virus Fixer companies so that they can study it and fix it. TIme will come after a month or so you may have your computer back to normal. Mostly virus sites were underground. For most protection don't dare visit. :)

How to keep your computer virus free


Many people that I have helped with computer viruses had recently purchased new computers which have virus protection included in the software bundle. The problem with these virus protection programs is that the updates are only good for the first year. After that, you must pay a fee to continue to get virus updates.

Many consumers don't realize this and after the year is up, do not renew the membership with the anti-virus company, leaving their computer unprotected from incoming viruses.

So, if you purchased a computer over a year ago, be aware of this problem. You will need to pay the yearly fee to maintain your anti-virus updates or get another anti-virus software available on the market.

There are some anti virus programs that are free or low cost. I have found AVG to provide a good quality free anti-virus program for home users. You can access the download at http://free.avg.com/us-en/download-avg-anti-virus-free.

Also, remember to be aware of emails from senders that you are not familiar with. Also be very careful about opening attachments on any emails. Be sure you know who sent them to you. Even then, if your not sure, verify with the sender that they actually sent this attachment to you before opening it. Email attachments are one of the most common ways of spreading viruses.

So, be careful and happy surfing!

Bought a hard drive & each time I put the cumputor on it tells me I have an invalid disc & wont let me start up till I pull out the conection.


This is going to be a very general answer because I have almost no information to go on.

You computer is trying to boot off the new drive (it thinks it is C:) and cannot because it is a new drive.

If your drive are connected with a wide cable (about 1.5 inches) you have IDE drives. If your drives are jumpered as Cable Select and on the same cable, swap the physical locations of the drives. Otherwise make sure your old drive is jumpered as Master and the new one as Slave.

If they are on separate cables, the old drive should be connected to the primary controller and the new one to the secondary. Since you are having problems, swap them.

If the cable is a narrow one (about 0.5 inches), you have SATA drives and you need to go into the bios to change the boot sequence. Because I do not know the make and model of your computer I cannot be specific, try pressing the DEL key as soon as you turn on the power, this method is the most common.

I also predict that your next question after this works will be why windows does not see the drive. But, that is the next question. Right now see if this works, if not please post the make and model of the computer, the make and model of the drive and your operating system.
