Possible virus

I think I may have a virus. my registry has leaked info and things are not acting right

it started when i blocked 3rd party cookie and a webb extenstion was acting funny.  

just read the do not specify list ie product name ect.  so im  not able to describe my problem fully

Norton will not talk on the phone. So i do not know what to do?

confussed  the rules below say do not metion the procuc t or service but they ask for it at the top of page.
