Two of the biggest concerns for computer users today are viruses and spyware. In both cases, while these can be a problem, you can defend yourself against them easily enough with just a little bit of planning:
- Keep your computer’s software current and
remember to install all patches. Remember to update your operating
system on a regular basis.
- Make sure your antivirus and antispyware
software, Microsoft Security Essentials, is using the latest
updates again potential threats (see How do I keep virus and
spyware definitions up to date?). Also make sure you're always
using the latest version of Security Essentials.
- Only download updates from reputable sources.
For Windows operating systems, always go to Microsoft Update and for other software always use the
legitimate Web sites of the company or person who produces it.
- If you receive an e-mail with an attachment
and you're unsure of the source, then you should delete it
immediately. Don't download any applications or executable files
from unknown sources, and be careful when trading files with other
users.
- Install and use a firewall. It is recommended
that you enable Windows Firewall.
