Hello. My name is***** can provide you with some additional assistance on your question.
The problem you are experiencing is almost always to to malware being installed on your system. Malware does not allow some connections, and particularly connections to the Google ad servers in this case.
If you have an ad blocker running, or if you have something blocking ads, that would cause a problem like this. It can also because by malware however. So I would suggest going to Malwarebytes.org and downloading the free product. When you installed the free product Alaska if you want to do a trial of the professional product – just select know there and it will give you the product that is permanently free. Then just run a scan with this and it will take some time – and then take note of the results. You find a lot of items then I would keep doing it again until it finds none.
Yes, Gary... wiping the drive and reinstalling would be ideal, and I suspect the other issues are related, too.
That would be the best solution, even better than the options that I proposed. It isn't my initial recommendation, because it often isn't taken as being correct advice since it will basically solve anything - but in this particular case, wiping the system is what I would do if it were mine. This virus is very difficult to remove.
