Back up data frequently.

Maintain layers of archived backups so you can retrieve a backup from a preinfected file.

Keep a write-protected, bootable diskette with the latest virus scan and removal software for all servers and workstations.

Keep a backup of executable files and flag them Execute Only.

Educate yourself about the infection techniques of the latest viruses.

Educate network users about how to detect viruses.

Warn users of the dangers of viruses. Discourage them from using diskettes and files that have been in computers away from work.

Teach users to power down their workstations immediately upon encountering a virus.

Restrict access to a server’s diskette drives by locking the server in a secure room. Put tape over the drive openings to remind you not to use them unnecessarily.

Avoid using the Admin account when possible. The fewer privileges your login account has, the less power a virus has to destroy data and to spread.
