This is a scam. It is designed to get you to buy a "fix" for your computer. I called Apple Support and they told me there was no problem with my computer. This is a way for these people to get inside your information and the money from you.

They try to install malicious software on your computer by asking you to visit their faked website is www.gotoassistant.com.
The male suspect on the phone has a strong Indian English accent.

I got a pop up window from disguised Url Mac-support-online.info. The popup sAid my computer is infected and should call 808-439-6801 to fix the problem otherwise there will be data & identity theft. The guy on the phone did not sound like an Apple Support person, had a very strong Indian accent, and  said he will fix my problem if I give him access to my computer. I asked him how he would access my computer.. He avoided the question and said to relax and not worry about it and just give him permission to take control of my computer. No way in h*ll so I hung up.

Popup on screen asking me to call 1-800-439-6801 for Mac support. Popup says my computer is infected with aware or malware.

pop up on screen…computer is infected call  apple system support at 808-439-6801 right away…i did call because i couldn't shut any of my windows down…strong indian accent….the pop up really looks like a mac warning.
hung up rep because accent way to thick to be a rep for apple…could hardly understand him.
