Security Center alert on every startup - Windows XP SP2
The Security Center in Windows XP SP2 verifies the security settings of your computer
(checks the status of anti-virus software installed, and the definitions; whether a
third-party firewall is installed or not). If the Security Center does not find a
firewall or anti-virus installed, it sends an alert via the Notification area. This is
to inform that the system security is at risk without a firewall or an anti-virus
program. Note that the Security Center can detect only a specific set of anti-virus
and firewall products/brands. In case you're running a firewall and anti-virus program
which the Security Center does not identify, it continues to alert the user on every
startup.
To turn off these alerts, try this:
Disable monitoring
Do this if you have a good firewall program and anti-virus with the latest definitions
installed.
Open the Security Center ( Type WSCUI.CPL in the Start, RUN box )
In the Security Center, under Firewall, click Recommendations. In the
Recommendations dialog box, select the I have a firewall solution that I'll monitor
myself check box, and then click OK.
Disable notifications
In some configurations, the above setting does not stick and the Security Center keeps
sending the alert again. If that does not work, try this:
Click Change the way Security Center alerts me. Clear the check boxes beside the items
for which you don't want to receive alerts, and then click OK.
To accomplish this via the registry
Open Registry Editor and navigate to:
HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Security Center
Backup the key by exporting this to a REG file. See here for more information
In the right-pane, set AntiVirusDisableNotify (REG_DWORD) and set to 1
Similarly, set FirewallDisableNotify (REG_DWORD) and set to 1
Close Registry Editor and restart Windows.
NOTE: If you choose the checkbox I have a firewall solution that I'll monitor myself
and the similar option for Anti-virus monitoring, both the values AntiVirusOverride &
FirewallOverride are set to 1. For more information on the above two registry values,
