How to protect yourself ?
DON’T OPEN E-MAIL from strangers or attachments you weren’t expecting. BACK UP IMPORTANT FILES on floppy discs. Zip drives or other storage devices so that they can be easily replaced if a virus wipes out your hard drive. INSTALL THE NEWEST ANTIVIRUS SOFTWARE on your computer. CHECK YOUR SOFTWARE VENDOR’S WEBSITE for updates that will protect against viruses.

Detectors only find infected files, but don’t destroy the viruses. Healers treat infected file structure and restore their content. Filters prevent the penetration of viruses into operating system.
