being bombarded with messages about W32.Imaut!gen1 in the QTFiles on my Mac

What is going on?  Just today I have been bombarded with MORE THAN 50n pop-ups saying that W32.Imaut!gen1 has been detected and deleted in the QTFiles and in the Norton folder,

 

This is happening so much that I can barely work with all the pop-ups.  I tried to turn all the notifications in Norton Anti-Virus 12.1 (54) on my Mac, to no avail.

 

Can someone please help me?

 

Thank you,

Peter
