Hi there ,
Security center might not detect an internet connection if there is a third party security software that interrupts the updates. So if you have any other security software installed on your PC, please try to uninstall them and then try updating McAfee.
Uninstall the other security software from Control Panel – Add/Remove programs (Programs & features in Vista/Win 7)
Also, their remnants from :
- C:\Documents & Settings\All users\Application data
- C:\Program files\
- C: C:\Program files\Common files

Wish I had a good answer for you but my computer started popping up a computer at risk message this morning also. My real time scanning and antivirus protection kept shutting down and as soon as I opened them they shut down again. Sometimes the computer would lock up when I tried to reopen them too since McAfee was using 100+% of the CPU. I was able to run Malwarbytes and it didn't find any infection. I finally used system restore to go to a point two days ago when I was sure everything was OK. After that I had McAfee check for updates and it took quite a while to download and install an update. Since then, my computer has been running OK. I kind of wonder if an automatic download earlier didn't work quite right and was causing my problems. Maybe that might work for you too.
And if that doesn't helps try to reinstall Mcafee.
