Computer VIRUSES


By Tony Robinson

A Computer virus is a program - a piece of executable code - that has the possibly of cloning itself. Computer viruses can spread fast and they are hard to eradicate. They can be attached to any type of file and they are spread as files copied and sent from person to person. They can be contacted from a floppy disk or Cd, they can be launched when opening a program or accessing a file, any file, or they can be brought from the Internet by downloading a file or accessing a web page and as attachments to e-mails.

Besides replication, some viruses have something else in common: their infecting routine. The behaviors of viruses vary from showing messages or images to destroying files, formatting the hard disk drive and other severe damage.

Never click yes when your browser asks you if you want to install or open some content coming from an organization you don't know or don't trust. 6. Install an anti-spy ware program to enlarge the protection. 7. Never install a browser help or search bar unless you know it comes from a reliable source. 8. Use a different credit card for shopping online. 9. Don't click on email attachments that are executable files even if they look as if sent from a known person.

The antivirus programs have a big role in providing your computers with security and protecting it from viruses, worms, and Trojan horses and other "invaders" that can attack a computer. The role of an antivirus program is to detect the presence of viruses in a computer, to disinfect the files, delete or quarantine the ones that can't be disinfected and prevent the computer from being contamination.

Most of the companies that produce antivirus have online free tools for scanning computers for viruses. If you don't have an antivirus yet and can't decide which one to buy you can enter their online sites and try the services for free, then decide what to use. I use McAfee and it works just great for me. I use to use Norton's but when my computer was acting kind of funny one day, I run McAfee and found viruses that Norton never even detected.
