Protect yourself from computer viruses

1. Buy virus protection software and keep it up-to-date.

2. Avoid downloading programs from unknown sources; stick with commercial software purchased on CD-ROMs.

3. Make sure that the Macro Virus Protection feature is enabled in all Microsoft applications.

4. Never double-click on an email attachment containing an executable program. These will have extensions like .exe, .com, or .vbs.

5. Consider switching to a more secure operating system, like Linux.
