So far only attempted to restart the UI service but keep getting error message !
Set Terminal server to Automatic start and verified Background Intelligent Transfer Services was set to Automatic start .
Will attempt to reinstall program next 
Running Avast on one Win 7 machine with no issues this morning !
Next day follow up :
Two machines corrected themselves and starting working normally after about an hour or so !
Two machines had to have the program re-installed after utilizing the Avast cleanup tool .
We’ve left one of the latter two machines w/shields disabled but so far no further instances of failure/lockups
