How to disable the "Your computer might be at risk" popup message in XP

If XP doesn't recognize the antivirus you have installed, you may find yourself constantly having to close a "nag screen" popup that tells you that your computer might be at risk because antivirus software might not be installed. The same thing can happen if you turn off the Windows Firewall because you're using a third party firewall. Of course, if you really don't have AV or a firewall, you probably should think about installing one. But if you just use a less-known security program that XP's Security Center doesn't "see," you can get rid of the message. Here's how:

1. 1. Click Start Control Panel and click the Security Center icon.
2. 2. In the left pane, under Resources, click the link that says "Change the way Security Center alerts me."
3. 3. In the Alert Settings dialog box, you can uncheck the box(es) for firewall and/or virus protection.
4. 4. Click OK.
   

Note: Applies to XP SP2 or above.
