Computer Virus Effects

Computer Virus And Its Preventive Mearsures.

 

What is a computer virus?

A computer virus is a program code written or programmed to disrupt functions of the computer system by replicating itself and spreading by attaching copies of itself to other applications or files in the computer system. It creates detrimental effects such as generation of irritating images, denial of some computer services or operations, corrupting data or the complete destruction and deletion of data and in some cases the whole operating system.

The Computer Virus Concept

Like a bio virus, the computer or machine virus does not act until when loaded or executed, this means that your PC might be infected for over a year without showing a single sign of infection until the virus is activated either intentionally or unintentionally.

If you  have a PC working fine and think your PC is safe and you didn’t apply any safety measures then i think you should rethink that thought right now because once the computer virus has been activated and you have nothing like a software or a mearsure protecting your files then you should know the virus will hit and hit hard.

How Computer Virus Spreads

How does the virus work?

The computer virus is tricky because when an infected file, application or any program in the computer system is infected it is hard to predict what effect it will give for instance if a virus infected your computer system first of all it attaches itself to a domant file and then replicates itself and spread preventing you from performing operations since its (the virus) operations are still in progress or ongoing. Let me explain, let’s say you have a computer virus like Commwarrior-A that has infected your system it at first becomes dormant until when the file, application or program is executed or opened by you or another user and if it’s a boot sector virus, it will not act or show its effects until the computer system is restarted or shut down then put on again.

Note:

A Computer Virus is different from a malware, spyware, etc. Let me claerify, Malware is the general term for any kind of infection your computer system may have. Then there are forms or types of Malware which are; Computer Virus, Spyware(monitoring), adware(ads violation), nagware(disturbs a lot), trojans(strong infections), worms, et cetera. So know now if you don’t know already that a Computer Virus is only a type of malware that is able to replicate, multiply or duplicate itself and spread through out the computer system and removable media like flash drives, phone USBs and others.

Effects Or Consequencies Of Computer Virus

  1. Corruption of the data in a file.
  2. Corruption of an application.
  3. The computer system seems to be controlling itself.
  4. Missing files or applications in the computer system.
  5. Deletion of files.
  6. Irregular opening and closing of files
  7. Inability to boot.
  8. Error loading a file
  9. Irregular looping of the computer.
  10. Unusual movement of the mouse and keyboard, et cetera.

Forms Of Types Of Computer Virus

   1.The Boot Sector :

A boot sector virus as the name implies act in the boot sector or area. It affects the parts of the computer necessary for booting such as the memory area and the disks such as the ROM and RAM. Its priority is to prevent a user from accessing the PC. The early signs are slow or long booting, booting and automatic restart then in the final stage it doesn’t boot at all, take precautions.

   2.The Network Sector :

This is a unique kindor Form  of computer virus, when a Computer User accesses and infected website, the virus on the infected website tends to replicate itself and spread from the server of the infected website to the server of the Computer User.

Whether or not you download something from the infected website, there is an 80% chance your PC might get infected. In the same way on a local network if a User or client tries to access some files on another user or client who’s PC is infected on the same local network, there is an 80% chance that the Uninfected PC of the User will get infected.

   3.The Window Area/Desktop Virus:

I call it the desktop virus because unlike the boot sector virus and the Network sector virus it attacks the PC on operation and off the Network. One might say its magic but it’s not.

This form of virus could come from a previously downloaded infected file or a copied file from a removable disk or even from within the system especially in slow PCs for the fact that it gets confused at some operations and corrupts a data ( its misunderstand an instruction from your mother).

From The Above One Might Say That the Medium Through Which A Computer Virus Infects A Computer Are;

Medium Of Virus Infection In The Computer

  1. The Internet.
  2. The Local Network.
  3. Removable Disks.

The Causes Of Computer Virus

  • Accessing files on a corrupted website
  • Accessing files on a corrupted Local Network
  • Opening mail messages from and unknown or and unidentified Sender.
  • Getting and opening files from an infected removable disk.
