text: internet viruses? how the viruses are working ?? how to protect my computer? a virus is a program pioneered by a highly skilled programmer who will code and create a virus to do whatever the programmer desires.  most viruses are not malicious and instead just tests by people to see how far they can go and what they can create. however many skilled programers create these to corrupt/delete files on a computer or to just alter a computers behaviour.  the best way to protect yourself is to install anti-virus software on your computer such as avg:  http://www.grisoft.com/   install this and you shoudl be virus free, it is the best free virus scanner on the internet but if you have the spare cash i would buy something like mcafee security centre that comes with a firewall which can help keep out hackers and some viruses.
