AVG premium scan freezes at 99% complete

Apparently, you have sent me instruction about making a screen snapshot of a Windows OS, I running on Mac OS 10.12.4.

Next I don't have a screen shot; however, I did copy the address when the machine froze:

/Volumes/BOOTCAMP/Windows/twai…0086/Local/0405/estwh.chm|>URLTBL
The last 6 character in the string might be URLTB< instead of URLTBL.

I will run the scan again to see if I can capture a screenshot when it freezes.
Thanks …john

John, To take a screenshot in MAC, please follow the below instructions : 1. To capture the entire screen, press Command-Shift-3. The screen shot will be automatically saved as a PNG file on your desktop with the filename starting with “Picture” followed by a number, example Picture 1, Picture 2, and so on. 
2. To copy the entire screen, press Command-Control-Shift-3. The screen shot will be placed on your clipboard for you to paste into another program like PowerPoint, Word, Photoshop, etc.
For your info, just in case that you are unaware, you can post the screenshot here in your topic. Click on 'Answer' & then click on the 'Image' [mountain symbol] & follow the instructions. 

In future please try to keep the whole conversation in one question/thread to speed up any resolution. Other posting (https://support.avg.com/answers?id=906b0000000DmXuAAK).
