Keep a complete and frequent backup. If you think a 40 megabyte hard disk is small, wait until you have to load everything back on your computer from scratch. The backup process can be easy if you give a little thought to how the directories are arranged on the hard drive. Although the backup is easy to do, because it's time consuming, it's the one aspect of viral recovery that gets blown off first. Keep file sharing to a minimum.
Data files are less susceptible to viral attacks than executable files.
Risk Group 2 and 3 users can do a combination of the above to keep themselves virtually virus free. If there's not one in your area, contact the Navy Computer Incident Response Team, at NISE East Det., Washington.
