Identifying and Removing Computer Viruses

Recognizing a Computer Virus

A computer virus is a program that damages or erases files or programs. Your
computer can become “infected” with a virus when you open a contaminated
program or file. Some signs that your computer may be infected include:

Strange characters or crude statements suddenly appearing on your screen

Hard drive, memory, or software error messages

Damage to files or directories for no apparent reason

Strange responses to commands

Sharp decrease in system performance or program speed

Using McAfee Anti-Virus Software

Your Internet PC is equipped with anti-virus software. Scanning your computer for
viruses is an important part of keeping your files safe from becoming infected with
computer viruses. However, hundreds of new viruses are created each month, so
you should update the anti-virus tool often.
