Safe Computing—Virus Protection

by Marilyn Cariola

By now, almost everyone at the lab knows not to click on unexpected attachments received in e-mail messages, particularly those from unknown persons. However, it still happens. Here are some tips to keep your computer safe.

• Avoid temptation. Do not click attachments you didn't request, including links and images sent via instant messages. Confirming someone meant to send you a file before opening it can save many hours of lost productivity and prevent irrecoverable data loss.

• Avoid, too, the temptation to install programs found on the Internet. Viruses are often hidden in executable programs. Download applications only from trusted Web sites at home and use only authorized programs at work.

• Always run antivirus software. It runs in the background and typically prevents viruses and worms from wreaking havoc.

Anti-virus software helps to protect from known viruses but cannot always protect from new ones. The antivirus signature files must be updated at least daily. For your SLAC-managed computer this is generally handled by Scientific Computing and Computer Services and your desktop administrator. Laptop users traveling for extended periods should get updates by connecting back to the SLAC network or through download from the vendor's Web site. On home computers, run full scans often. If you have children using the computer, do it at least once a week.
