Last night I did one more fresh install of AVP after running MVT and MCPR. Just to prevent product instability I disabled McAfee updates and see how long it runs. Manually started a full virus scan of my PC using AVP before went to bed. In the middle of the night McAfee Anti Malware core had crashed again. With that now I am back to the Real Time Scanning Off issue and nothing else works. The virus scan also I presume didn't complete as I don't see any record of it in the AVP Security History log. I am using the McAfeesetup.exe that I had downloaded when I entered my product code initially. I cannot get another copy of this since McAfee says I already have used the product code. But I believe McAfeesetup.exe is getting the latest copy of AVP each time it executes.
I am bit hesitant to go to McAfee support because this similar product instability issue has happened to me before 3 years ago. The tech support took control of my PC and they did something to fix it but didn't tell me what they fixed and how they fixed it. After that episode the next 3 years I used different security products before trying with McAfee again this year. Will give it couple of more tries before I move on to some other security product.
Well there are two obvious, to me at least, reasons that could be the cause of this, 1) disabling updates will cause errors in the end, as soon as 12 - 24 hours in fact, and 2) using the installer that you originally used is installing an old version most likely so the problem will simply reappear.
Every McAfee user that has ever registered or activated a product has an online account page where they can always download the very latest version of the software.
You are in the USA so it's here: https://home.mcafee.com/secure/protected/login.aspx?rfhs=1 or if you get yours from your PC maker or ISP there may be a special account page which they must have provided you with at some stage.
So the point I'm making is, go through the uninstall via Control Panel, run a fresh copy of MCPR and reboot and then download from your online account and nowhere else.
Otherwise your only hope is Technical Support, they are good and they are free and available by phone or online chat and linked under Useful Links ta the top of this page
Also try seeing if the process is active. Open task manager [CTRL+ALT+DEL] and select "services". Sort by description and find the McAfee anti-malware core service, and then check its status; from what it looks like all McAfee processes except McODS should be set to running.
Thankfully the MVT also will do this process automatically, if ya don't want to fiddle with the process manager.
