System has to be restored every couple days when running Audition

I use a mid 2011 iMac running Sierra.  For the last 2 weeks I have had a recurring issue where my system "lags" out to the point that getting a mouse click to register takes up to 90 seconds.  During this time, no programs can be closed out and the system can't be shut down or restarted.  Then, I eventually do a "hard re-boot" and the machine stays on the loading screen for hours.  So I end up restoring from Time Machine.  It works PERFECTLY for a couple days, then I have to do it again.

The ONLY common programs that have been running during these issues are AUDITION-CHROME-and-AVG.   I have updated ALL related programs.  Uninstalled and re-installed and have had no success in fixing this issue.

Is anyone else having this same issue?  What am I doing wrong?
