Ok
It's apparently called the lucky.happyparkclub.com virus.
I found that my Google chrome settings had an exception for this site that allowed pop ups.
I removed it. Let's see what happens.
Thanks. I'll look into mine.
ETA:
I did a bit more digging, and apparently it's not a virus, but an ad
from this site.
So, it may be a simple case of not allowing popups from this forum and that should take care of it. I will check my iPad settings when I get the chance.
On the Apple forum it recommends staying away from the site (this one) as it may be hacked or is prone to sending SPAM.
Any thoughts JMT?
