McAfee Real-Time Scanning prevents file access

I have been having this problem for some time. At times after logon, when i try to open a file in my drive it pops up a windows error dialog saying 'Windows cannot access the specified device, path or file. You may not have the appropriate permissions to access the item.'

Earlier, i used to solve this by restarting my system and everything would be back to normal. I thought it was just a glitch or someting due to any windows updates. But it started popping out more frequently that i had to find the cause for this issue. And then i figured out that somehow the Real-Time scanning feature in McAfee was causing this all along. I confirmed it by accessing the file(tried with my personal image and document files) by turning the feature ON and OFF. I was able to access the file when it was set to OFF. Now i really don't have any idea as of why this popup occurs and i do not know if it has to do with any setting/changes i had made inside of McAfee. I require support/solution for solving this as of what had gone wrong with my system. And thanks in advance.

Note: when this popup occurs, it occurs for .jpg .png images and .pdf documents (so far) in both of my hdd/ssd drives. It does not occur for any video or .txt files. The only workaround i have been trying is to restart the system (or) turning OFF the real-time protection when i need a file to be accessed.

Re: McAfee Real-Time Scanning prevents file access

I have repeated this clear and reinstall process 3 times, and it keeps recurring (unable to view JPG files).  Whenever I need to view JPG or MOV files, I need to turn off Real Time Scanning.  Upon reinstall it will work for a few days, then files are blocked again.  Extremely frustrating!

Re: McAfee Real-Time Scanning prevents file access

Did you or anyone find a solution to this problem, other than reinstalling McAffee as the techie outlined?  I have this problem too and have found no solution anywhere.   Thank you in advance for any help you can provide.

Re: McAfee Real-Time Scanning prevents file access

Yes, with LiveSafe Real Time Auto Scanning turned on I cannot open any Office file (e.g. Word or Excel file) attached to my emails either using the Edge or the Chrome browser. This quite severe problem only started occurring in the last 2 or so weeks (i.e. probably a recent McAfee software update). If I turn off the McAfee Auto Scanning feature the Office files open fine, no problem. Help please?
