Prevention is better than cure. So stay alert and be careful with the cracks, warez sites, porn sites and Peer to Peers sites you visit. Viruses often come from such websites to your computer.

During the installation of a software, do not click on the “Next” button that you are always faced with without reading what is marked and what is ticked.
