When your computer is sick, it never hurts to get a cat scan. :-)
The first line of defense in the war against computer viruses is simply to be alert when opening your email. Most of today's viruses are transmitted via emails that appear to come from legitimate sources. If you are not expecting a package from UPS, don't open that UPS attachment giving you instructions on how to get your package that could not be delivered. (UPS will hang a tag on your door if you are not at home.)
