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.
