What are they? Malicious small programs that easily replicate themselves, infect your computer, and often spread to others computers via email attachments or network traffic.
What risks are involved? Virus programs can delete files, format disks, attack other computers or slow your system. They can also create “back doors” that allow hackers to run programs on your computer or to gain access to your files. How do I know if I have a computer virus? A computer infected with a virus may suddenly act in unexpected ways. For example, it may take longer to access files or to start up programs, or it may lock up often. You may also notice uncommon sounds being played from your speakers, a variety of images popping up on the screen, or problems starting your computer. These are all signs that your computer could be infected with a virus.
