What is virus

A computer virus is a program that spreads

by first infecting files or the system areas of

a computer or network router's hard drive

and then making copies of itself. Some

viruses are harmless, others may damage

data files, and some may destroy files.

Viruses used to be spread when people

shared floppy disks and other portable

media, now viruses are primarily spread

through email messages.

Symptom VIRUSComputer virus symptoms are a not cast in

stone, but rather a moving target. Just like

with the human viral conditions, they

evolve through generations – which in

computer technology terms may mean

weeks or even days. Some symptoms may

not necessarily mean an infection – for

example, if you are sneezing, you do not

necessarily have a flu, it may be just an

allergy – which means different cause, and

different treatment methods. Same with

computers – if your system seems to be

slower than usual, it may be a symptom of

a virus, but it may also be a symptom of

“program overload” – when you have too

many programs running at once, and it

crashes  your computer system’s

performance.

AntiVirus Technique1. Antivirus protection is strongly recommended. If you are not

an expert in computer security, you should ensure that you employ proprietary antivirus protection and a firewall. The majority of the current antivirus programs provide protection against all types of computerized threats, including viruses, worms, Trojans and adware, etc. Integrated security solutions are also capable of filtering spam, preventing network attacks and restricting access to unwanted and dangerous Internet resources.

2. Do not trust any information whose source cannot be guaranteed, whether in email, hyperlink, IM or other format. Do not open files and links from unknown sources. Even unexpected messages from friends or colleagues should be treated with caution as a sender’s address can easily be forged. The Internet can be a dangerous place and you need to remain constantly vigilant.

3. Do not neglect information from antivirus companies and IT security experts. They usually provide an early warning about any new type of Internet fraud, virus threat or epidemic that may be circulating.

How to Remove Viruses

First you need to determine if your computer has a virus at all. You might suspect your computer of having a virus if it seems to be sluggish. If your Web browser suddenly looks different or automatically goes to a site you don't recognize, that's a good indication that you've got some malware. If your computer is unstable and crashes fairly often, you may have a problem. And if you try to access files but receive a message saying they're corrupted, that's another sign. If you do think your computer has a virus, you need to run antivirus software to weed it out. Some viruses disable antivirus software -- they're clever that way. If you don't have any antivirus software, now's a good time to purchase or download an application. A few malware variants will try to block you from downloading antivirus software. If that's the case, you may need to download the software on another computer and transfer it to disk or a flash drive. Beside that, you can identify the virus. Run your antivirus software to identify the name of the virus. If you don't have an antivirus program, or if your program does not detect the virus, you can still identify the virus by looking for clues about how it behaves. Write down the text in any messages displayed by the virus or, if you received the virus in e‑mail, write down the subject line or name of the file attached to the message. Search the antivirus vendor's website for references to those specific things you wrote down to try to find the name of the virus and instructions for how to remove it.

Keep your antivirus program up to date.

Conclusion There are lots of viruses in the world and new viruses are

coming up everyday. There are new anti-virus programs and

techniques developed too. It is good to be aware of viruses and

other malware and it is cheaper to protect you environment from

them rather then being sorry.

This is a suitable place to remind you that when working with a

computer, the rule-of-thumb is "better safe than sorry". This

means the following:

• always make backup copies of your files,

• check all floppy disks, CD-s and files downloaded from the

internet for viruses,

• do not allow your computer to be used by random

acquaintances,

• update your antivirus software at least once a month.
