After the update, internet seems slower

Ever since the auto update to v20.1.1.2 BOTH IE and Firefox are much slower.  Even going to Google takes too long.  Is there a setting that was set automatically & can I undo it. I disabled the Norton toolbar in both - but still slow. 

 

Have run a full scan, used CCcleaner & MRU Blaster - still no luck.

 

 

Help!
