Friends, not only computers are infected by viruses, but we, human beings can also contract virus from computers!
Indeed, a study carried out by British scientists concluded that your mouse and keyboard harbor more bacteria than a toilet!

If you do not wash your hands after the toilet session, and use your keyboard and mouse, the subsequent user of the PC has a risk to be infected.
In cybercafes, often internet users, surf whilst eating (perhaps enjoying the flavour being added to their food from the unwashed hands of the previous PC users).
So friends, whats the antivirus?? Oops..I rephrase it: how to avoid being contaminated from such virus?
Solution: 1) clean your keyboard and mouse regularly 2) wash your hands before using the computer
