Some people say don't use bulletin boards, don't swap any Public Domain programs, don't get software from user groups, don't let anyone touch your machine. This is silly. It's like giving up walking because you could be hit by a bus. If there is a danger you take reasonable precautions, but you don't panic. This next section attempts to provide virus protection "By the Numbers" for the technically uninitiated.
To give a basic outline:
1.) Use a detection program to make sure your system is clean.
2.) If it is not clean, use an eradication program to clean it.
3.) Install a protection program.
4.) Use a detection program to check all incoming disks.
