System: Dell XPS 8700, Windows 10 Pro 64 bit, version 1803. Windows Defender, Malwarebytes 3 Premium, all current. I am hearing from serious and credible Windows experts that it's unwise to have more than one program at a time doing real-time scanning, because of possible interference. They are saying use MB as on-demand scanner, but don't activate the real--time detection features. So I am asking what to think of this advice, and for an explanation (as technical as may be necessary) for why MB will not interfere with Windows Defender (and vice versa), and/or what precautions are advisable to prevent interference from occurring. I have previously run MB alongside Avast Premier without observable problems. I did have problems with a newly installed UHD monitor (blackouts, system freezes etc.). Some thought that MB and/or Avast were responsible. That seems not to have been the case; removing CCleaner Pro seems to have solved that problem. I cannot claim to be a Windows expert, or a security expert, but I've been in computers for a long time (since before they were electronic), written software (mostly database apps) in mainframe and PC environments, built and maintained corporate networks, etc., so I might be able to understand an explanation of how MB avoids interfering with Windows Defender (etc.), if that is indeed the case. And of course I also understand confidentiality limitations. Thanks for any enlightenment you can provide.

I'm pleased to report that this fix worked. I did not have to reinstall. Needless to say the user is delighted. Thanks very much, John

Thanks Grant, no he did not. I am ready to try whatever you recommend. John

I have run into the same problem on a friend's computer for which I have the maintenance responsibility. We had some dialogue at the time with Tom Mercado of your support staff, but no satisfactory resolution. Thumbnail specs of that computer: HP Media Center, Win Vista Home Premium (x64) SP2 fully updated, Microsoft Security Essentials, SpywareBlaster, MVPS Hosts file. MBAM free edition. This computer is connected to the Internet via a Hughes.net satellite modem, linked to the computer via USB 2. Mouseover on the network connection icon in the system tray shows Currently connected to: Network 2, Access: Local only. Internet browsing (MSIE 8.0) and E-mail (Windows Mail) work normally. Have tried updating with and without a browser window open. No difference. When this first arose about a month ago, owner went to Microsoft online help, the MS tech took over the machine using TeamViewer software and was able to update MBAM. A few minutes after he signed off, I was able to update MBAM again - but not since then in spite of multiple attempts. I do NOT have this updating problem on my own computer (Win XP Home SP3 fully updated, Avast! free, otherwise as above but on dialup connection with conventional modem. Currently running MBAM 1.51.0.1200 and no problems updating. That is the computer from which I am posting now (the other one is 3/4 mile down the road). Thanks for any advice, John
