Leo's guest today is Steve Hunt, who's a weird hybrid of locksmith and computer security consultant. A virus is a program or piece of a program that is loaded onto your computer and runs against your wishes.
Viruses are manmade.
Even a simple virus is dangerous because it may use all available memory and bring the system to a halt. More dangerous viruses can delete or change the data on your hard drive. Viruses can be found and removed using antivirus software available at your local software store. I use McAfee, but Norton is good, too. Email is a terrific way to stay in touch with family and friends, and to make new friends.
