Computer viruses are software programs deliberately designed to interfere with computer operations, record, corrupt, or delete data, or spread themselves to other computers in the organisation and the network, often leading to disruption of work affecting your productivity at work. Computer viruses range from the mild annoyance to the downright destructive, and come in many different forms. The good news is that with an ounce of prevention and a little knowledge, you are less likely to fall victim to viruses and you can diminish their impact.

The following are the tips to help avoid or spreading of viruses:


Use an updating mechanism or system that would update all computers in the network automatically when new updates are available.


Set your computer OS and security applications (anti-virus, anti-spyware, firewalls) to update automatically.


If a computer is infected, isolate the infected computer from the network.


If malicious code exploit one of more of the network services, block access to that service until it is rectified.


Use a Internet firewall.


Never open an e-mail attachment from someone you don't know.


Avoid opening an e-mail attachment from someone you know, unless you know exactly what the attachment is. The sender may be unaware that it contains a virus.


Keep you network servers updated that host public services, e.g. HTTP, FTP and Email services.


Email servers should set to block or remove email with attachment used to spread virus, e.g. .VBS, .BAT, .PIF, .SCR, .EXE files.
