computers issues

[Dznypal]

I had posted several months ago that I was having issues trying to do the rewards programs where you just look at an ad for a few seconds

and get points which you could cash in for $ or GC
I got some very helpful replies following the advice I was back up in no time

now Im having again not the same ones though
now when I type in the name of a program I get a message
connection is not private
and hackers could be trying to steal my passwords messages or CC (I dont have my CC tied to these programs
this is using the brave browser which someone on here suggested which has worked for months

if I click on learn more about this message it suggests using in congetico which i tried and that doesnt help anything
its started out with only one program where Im getting this message but now its several

any ideas
