A computer virus is a computer program that can copy itself and infect a computer without the permission or knowledge of the user. The term "virus" is also commonly but erroneously used to refer to other types of malware, adware and spyware programs that do not have the reproductive ability. I think all of you know about that, so this is some way to avoid the virus infected computer:
1. Use Antivirus that you believe with always update, regardless of any kind is always provided in the update, and automatically switched protection
2. Always scan all external storage media that will be in use, this may be making a bit but if you Autoprotect anti-virus work then the procedure can be missed
3. If you connect directly to the Internet to try to combine with your Antivirus Firewalls, Anti spamming, etc.

If your computer has been infected with the virus, then do :
1. Detection and determine where some of the virus. whether the floppy disks, network, email? etc., if you are connected to the network then it's good you isolate your first computer (either with cable release or disable the connection)
2. Identification and classifying the type of virus that attacks your computer, the following manner:
- Symptoms that arise, for example: the message, the file is missing or corrupt etc.
- Scan with your antivirus, if you are exposed to when running Autoprotectvius in the definition means that you do not have a computer virus this data, try to manually update or to download a virus definitionnya you install. If the virus to block efforts to update then, strived to use other media (computer) with antivirus update.
3. Clean, after you successfully detect it and then try to seek immediate removal or how to destroy the sites that provide information of the virus. This latest update antivirus if you do not succeed destroy it.
4. The worst, if not all of the above is successfully re-format your computer.
