My windows security center shows that windows did not find a antivirus program installed. I only use avast and this was working fine until I went into control panel to look at my power option settings. I always had these settings set to never. One of the tabs is labeled APM. After I unchecked "enable advanced power management support" this problem showed up in windows security center. I have uninstalled avast and removed all files and then downloaded the most recent version but problem still exists. I am using windows xp with sp2. How do I get windows to recognize avast again? Thanks for your time.

Anyway, if you disable and then enable the Security Center, will it help?
Are your system date and time correct?
date and time are correct. Went to windows site and downloaded wmidiag tool. Utility reports that two files seem to be missing. Cmdevtgprov.dll and policman.dll. I tried re-installing them using my original xp disc but after 20 minutes of windows checking for missing files I still have the same problem. Still searching for answers. Thanks for your time.
