Is it just my experience but are there an inordinate number of scammers out there recently? Its really shot up over the past year.
Popups and such claiming that your computer is infected is an old scam. However one is born every minute.
Ping to dayglored; Shadow Ace; ThunderSleeps for your ping lists as well as there is spill over.

If you want on or off the Mac Ping List, Freepmail me.
I got the Safari message on my iPad. I called because it is my mission in life to waste as much of their time as possible while teaching them American slang.
Thanks, I forwarded this to our DIL.
Her son, our grandson, got scammed in the first week of school this fall semester at his new private school
We bought him the new Mac Air for his new private school. He got the phishing scam in the first week of school and fell for it without notifying his parents. When his mother came home with his sister, he told her that his Mac wasn’t working.
He showed her the warning, and she used her credit card to “clear up the problem”.
A few minutes later while limoing he and his sister to after school events, she got a text from her credit card that she had been phished and scammed.
She called the credit card and was told that the Mac repair people were scammers. They were sending her a new card.
The next morning she took the mal wared Mac Air to the local Apple store, they removed the bad stuff and told her to
never do that again.
Several of her son’s classmates got the same bad message. The phishers apparently targeted the new incoming freshmen.
Maybe, the upper classmates were too computer wise to fall for this.
A week or so later, her home office Mac got the same message. She knew what to do.
I didn’t talk to our DIL about this incident, my non techie wife did. So the specifics may be not that specific.
Thanks again.
