What operating system and service pack (if applicable) is this and what version of Internet explorer is installed (whether or not you use IE)?
I wouldn't worry too much about Windows Action Center as long as the McAfee SecurityCenter is showing everything is fine but you could try running the Virtual Technician to see if it finds and fixes any problems:
Windows 8 is my current OS and I only use Google Chrome.
I ran the Virtual Technician and it found nothing.
I feel better now, as the McAfee SecurityCenter says nothing is wrong and everything is running fine.
Thanks so much for your help!
OK - sounds good but I did say that IE didn't have to be used, I just need to know what version was installed. Some programs in Windows itself and McAfee SecurityCenter rely on IE for functionality.
So make sure that IE is up to date, i.e. IE11. You do not need to set it as default browser to do this, but installing IE11 may help the situation you described also will make Windows more secure as an added bonus.
Just thought I would throw this in as well, For I also experienced the same occurance a couple of times over the past few years. As Ex_Brit stated, the most important thing is that your MSC states that your are "Secure and Protected"
Here is the link...Just noticed that your operating system is Windows 8, However this suggestion should still apply, again just a simple "Restart"
I have came across this in one such case where McAfee Security needs to be trusted by Windows Security Center. Just go to the WSC and Click turn ON for VirusProtection / Firewall components -> You should receive a dialogue box whether to Trust or Untrust the Application. Click on Yes/Trust and we are good to go..!
