How to Eradicate Computer Virus Spread


According Muammar (2004), there are two steps in tackling the spread of computer viruses, namely:
1. Measures for prevention
You can do some preventive measures as follows:

  1. Use antivirus you trust with the latest updates. Whatever the origin of the brand is always updated and auto-protect is turned on, your computer is protected.
    For example, boot sector detection. Antivirus is a good protection for your computer and serves to activate the boot sector virus detection that will ensure the boot sector (on the hard disk drive) free from viruses. This facility is a new antivirus solution that is rarely found in other antivirus. Antivirus works by protecting the partition and boot sector of the hard disk drive writing process. Thus, the computer will be free of viruses that may be active on boot. The computer will stop (halt) and displays a warning message if found any virus or an attempt writing to the partition boot sector or hard disk drive. If this message appears, can still force the computer to operate by passing a message, or can reboot the computer by using a clean boot disk and existing antivirus. Given the protection and the process of writing to the partition boot sector of hard disk drives, in some circumstances this facility should be shut down. For example, when installing the operating system (for example Windows9x) are in the process of installation make changes to the boot sector of hard disk driver.
  2. Check all external storage media to be used. If the antivirus auto-protect your work then this procedure can be missed.
  3. If you are connected directly to the Internet, try to combine antivirus with firewall, anti-spam, and so on.
  4. Be aware of suspicious files such as files with 2 extensions and executable file that looks suspicious.
  5. For the form of freeware and shareware software, you should take it from the official website.
  6. Try not to buy pirated goods, use of open source software.

2. The steps when they have been infected

  1. Detection and prediction of the existence of the source virus. If you are connected to a network, it is better insulation first computer either by unplugging or turning off the internet connection from the control panel.
  2. Identify and classify the type of virus that attacks a computer, by the way:
    The symptoms, such as corrupt or missing files.
    Scan with your antivirus. If you are exposed to when auto-protect running means the virus definitions on your computer does not have this virus data. Try to manually update virus definitions or download it for you and then install. If the virus is to limit your efforts to update, try to use other media (computer) with antivirus with latest updates.
  3. Clean the virus. Once you have successfully detected and recognized, try to immediately find ways their destruction at sites that provide information on the progress the virus. This needs to be done if your antivirus with the latest updates do not succeed destroy.
    · The final step is a step worst. If all the above does not work, reformat your computer.
