On Safari, I received a notice my computer has adware/spyware virus.
While on Safari, I received a notice: http://www.mac-firewall-alert.com
(1) Mac Firewall warning:
YOUR COMPUTER HAS ADWARE / SPYWARE VIRUS
Then I'm given a phone number to call which was toll free. The person I talked with said he was with Rapid Info Technology. I could hardly understand his accent. I was skeptical, of course - but the notice on my screen could not be deleted, nor could I close Safari. I finally shut down the computer and tried again. Same thing. This time I shut Safari with Control-Q and opened Google Chrome. That notice did not pop up there. I will go more into my discussion with the gentleman I spoke to -- if there's anyone out there in this Apple Support Community that has heard of this happening. Thanks!!
