Malware attack by universal-current

i seem to have been infected by some sort of malware. I keep getting pop ups in right corner, which seem to be linked to 'captcha_ one' . The Norton scan does not pick up anything and i am stuck.  When i click on the links , it takes me to a page which is blocked by Norton, but seems to be linked to universal-current.  

A word doc showing screen shots if some the infected ad that appear on the screen, is attached. 

I would really apricate any help, please.

I have Norton360 running on a windows asus laptop with windows 11

Many thanks
