Mac Endpoint "unknown error received from scanners"

Hello, I've been having difficulty with Mac Endpoint 10.7.5 Security's "Scan now". I keep getting an "Unknown error received from scanners" error. I wonder if it is related to my DAT creation date? I am running MacOS Catalina 10.15.7

Under the Treat Prevention Update I see:

Engine version: 6200.9189

DAT version: 4519.0000

Last Update Status: Successful

DAT creation date: 1/1/70

Of note, I recently upgraded to Endpoint Security for Mac 10.7.5 RTW standalone 226 from an older Endpoint product. When upgrading to this new product, I was unable to fully uninstall the old one (even after using "sudo /usr/local/McAfee/uninstall EPM" and restarting my computer, I still saw the application in my Applications' folder). After upgrading to 10.7.5 I have already given full disk access to the necessary scanners. I had previously had a similar "unknown error from scanners" when trying to update under the "Update now" tab but this was corrected when I manually downloaded a V2 DAT update. 


Thanks in advance for your help!

Hi @Michael_,

Good day to you!

Could you please check and confirm the OS that is currently being used?

Additionally, please provide us with the screenshot of the error that you have mentioned for us to check this further.

The ENSMTP 10.7.x uses the MED DAT and no longer uses the V2 DATs.

Hi @AjaySundar 

Thank you for your help and apologies for my delayed reply! I did confirm that the OS is Mac 10.15.7 Catalina. Attached you will find a screenshot of the error I receive when attempting to scan. I also included a screenshot of the DAT/Engine version with the erroneous date.
