Maintain your virus scanner. Your computer support staff may handle this for you, but ask about a virus scanner and what you need to do to keep it up to date. If you have a problem that you think might be related to a virus, tell someone who can help. If you are wrong, you might feel a little silly, but that is much better than losing your work or spreading a virus to someone else. Know the limits of your virus scanner.
Virus scanners are very powerful tools, but they have limits.
For instance, they need to be properly configured to provide e-mail protection. Also, virus scanners sometimes disrupt software installations and need to be temporarily disabled. Disabling a virus scanner may sound silly, especially during software installation. However, you may need to disable the virus scanner to complete an installation. Just remember to enable the virus scanner when you are done with the installation.
