A computer virus destroys all the data files & programs in the computer memory by interfering with the normal processes of the operating system.
Precautions against computer viruses:
Anti-virus software.
Use Antivirus software to detect & remove known viruses from infected files.
Some of the commonly used Antivirus software are: Dr. Solomon’s Toolkit, Norton
Antivirus, AVG Antivirus, PC-Cillin, etc
NB: The best way to prevent virus is to have a memory-resident antivirus software, which will detect the virus before it can affect the system. This can be achieved by installing a GUARD program in the RAM every time the computer boots up. Once in the RAM, the antivirus software will automatically check diskettes inserted in the drives and warn the user immediately if a disk is found to have a virus.
- For an antivirus to be able to detect a virus, it must know its signature. Since virus writers keep writing new viruses with new signatures all the time, it is recommended that you update your antivirus product regularly so as to include the latest virus signatures in the industry.
- The Antivirus software installed in your computer should be enabled/activated at all times.
- You should also perform virus scans of your disks on a regular basis.
- Evaluate the security procedures to ensure that the risk of future virus attack is minimized.
