Recognizing a Computer Virus

A computer virus is a program that damages or erases files or programs. Your Notebook can become “infected” with a virus when you open a contaminated program or file. Some signs indicating that your Notebook 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 performance or program speed

Removing a Virus

If you suspect your Notebook has been infected with a virus, find and remove the virus immediately using an Anti-Virus program.

After you have followed the instructions provided by the Anti-Virus program, complete the following steps:

1.Turn off your Notebook and leave it off for at least 30 seconds.

2.Turn on your Notebook and rescan for the virus.
