It can copy itself and infect a computer without the permission or knowledge of the owner.[1] Computer viruses are spread through internet downloads, most commonly through email attachments. These attachments are meant to entice the user to click on the link that will lead to the download of a funny image, greeting card, or audio and video files, but in truth is actually downloading the virus to their computer system. [2] A virus is capable of reproducing itself and usually capable of causing great harm to files or other programs on the same computer. [3] A computer virus is capable of deleting or corrupting data on your computer on your hard disk. Viruses can be spread via email message or instant messaging messages. That is why it is important to keep your computer up to date with the current antivirus tools and latest updates. [4]
