    Loss of Network Connectivity post Security Centre Update

      Have a recurring problem since  my Security Centre updated to Version 11 last week.; not sure if this should be a new post or not, as I saw passing references to similar problem under the “Real Time Scanning Keeps Turning Off” post. (although no prob with my Real Time Scanning). Basically, I have to reinstall my network adapter driver every day after start-up to restore connectivity & have the following recurring events:


      • Windows Defender Real-Time Protection agent has detected changes. Microsoft recommends you analyze the software that made these changes for potential risks. You can use information about how these programs operate to choose whether to allow them to run or remove them from your computer.  Allow changes only if you trust the program or the software publisher. Windows Defender can't undo changes that you allow.

      I did do a Restore last week when trying to re-establish connectivity (not well tolerated by McAfee, I know), however, I have also run MVT (nothing), McAfee full scan (nothing), Anti-Spyware (Spybot, Super-Anti Spywaye & MBAM) which also found nothing. The only thing I haven’t done is Uninstall & Reinstall McAfee; should that be my next step? Before I do, any known reasons why Mcafee system filter drivers would be interfering with any other drivers?


      My Current Sys Specs are:

      Please & Thanks. GB
