Windows Action Center (Windows Security Center)
checks for many common anti-virus, anti-malware and firewall programs, but it's possible that you might be using a program that Windows cannot detect or is having issues with. Windows Security Center will try to tell you about anti-virus, anti-spyware, and firewall programs installed on your computer but it does not detect
all software brands. If a manufacturer decides not to participate, the Security Center will not be able to detect the manufacturer's programs. It is the responsibility of the anti-virus, anti-mallware or firewall vendor to design their software so that it will be recognized by the Windows Security Center. The vendor also must submit the information to Microsoft so the Windows operating system catalog can be updated with the software signature addition.
Below is a note Microsoft included under the section Malicious software protection
which can be found in their "Using Windows Security Center" support article.
Using Windows Security Center
Windows does not detect all antivirus and antispyware software. If you are sure that you have anti-malware software installed, it is turned on, and it is up to date, you can click I have an antivirus program that I'll monitor myself or I have an antisypware program that I'll monitor myself to stop receiving notifications from Security Center about your anti-malware software. If you do this, Windows will not monitor your anti-malware software status or alert you if it is off.
Further, if there was a previous anti-virus installed, you need to ensure it has been completely removed. If not, there may be conflicts when attempting to install a new anti-virus to include it not being recognized by the Security Center. In many cases vendors offer clean-up utilities
to remove remnants left behind after unintalling.
If you did not have a previous anti-virus or the above does not resolve the issue then refer to:
-- Note: Some types of malware will disable or corrupt the Windows Security Center. The above suggestions are only for this issue if you're sure there is no infection on your computer.
