These are phishing scam malware. Ignore them. If they do not go away then:

Helpful Links Regarding Malware Problems

If you are having an immediate problem with ads popping up see The Safe Mac » Adware Removal Guide, remove adware that displays pop-up ads and graphics on your Mac, and AdwareMedic. If you require anti-virus protection Thomas Reed recommends using ClamXAV. (Thank you to Thomas Reed for this recommendation.) You might consider adding this Safari extensions: Adblock Plus 1.8.9.

Open Safari, select Preferences from the Safari menu. Click on Extensions icon in the toolbar. Disable all Extensions. If this stops your problem, then re-enable them one by one until the problem returns. Now remove that extension as it is causing the problem.

The following comes from user stevejobsfan0123. I have made minor changes to adapt to this presentation.

Fix Some Browser Pop-ups That Take Over Safari.

Common pop-ups include a message saying the government has seized your computer and you must pay to have it released (often called "Moneypak"), or a phony message saying that your computer has been infected, and you need to call a tech support number (sometimes claiming to be Apple) to get it resolved. First, understand that these pop-ups are not caused by a virus and your computer has not been affected. This "hijack" is limited to your web browser. Also understand that these messages are scams, so do not pay any money, call the listed number, or provide any personal information. This article will outline the solution to dismiss the pop-up.

Quit Safari

Usually, these pop-ups will not go away by either clicking "OK" or "Cancel." Furthermore, several menus in the menu bar may become disabled and show in gray, including the option to quit Safari. You will likely have to force quit Safari. To do this, press Command + option + esc, select Safari, and press Force Quit.

Relaunch Safari

If you relaunch Safari, the page will reopen. To prevent this from happening, hold down the 'Shift' key while opening Safari. This will prevent windows from the last time Safari was running from reopening.

This will not work in all cases. The shift key must be held at the right time, and in some cases, even if done correctly, the window reappears. In these circumstances, after force quitting Safari, turn off Wi-Fi or disconnect Ethernet, depending on how you connect to the Internet. Then relaunch Safari normally. It will try to reload the malicious webpage, but without a connection, it won't be able to. Navigate away from that page by entering a different URL, i.e. www.apple.com, and trying to load it. Now you can reconnect to the Internet, and the page you entered will appear rather than the malicious one.

On May 8th, 2015 I received a call from a guy saying he was with SpyTech and my computer internet connection had been taken over and 6 other computers were using it. He acted like he worked for Microsoft and Apple, but after questioning he said he just worked on that system. I asked him how I could confirm he was not a scammer?  I asked him to send me an email. He claimed the problem was too urgent and I need to go to fastsupport.com immediately. I recognized he was scamming me and hung up, but he was pretty convincing.

This is the first I've read of this scam happening over the phone.

Thank you for putting this up. I was directed to the "technicians" also. I was on the phone with them when I started to get suspicious. I found this and asked the them questions which they avoided. I hung up but they called me back. I accused them of dishonesty and asked them not to call again.

Thank you to all for submitting these posts, I just received the same phone call and they originally asked me about Windows and I said I had a MAC and they transferred me to the MAC department and they lied and said they were from Apple, I hung up on them at that point.  This has to be illegal or something...

I was out on HP's site looking for support on a printer driver issue. Somehow I managed to get in a chat session and phone call with these FastSupport bozos. Must have been a popup I mistook for legit HP. They were trying to scare me into buying a "warranty" so they could "clean" my MacBook Air (oh boy). I finally wised up and shut down. Powered back up and ran Norton System Scan - found nothing. No harm done - I hope.

Of note: www.fastsupport.com is the connection link for Citrix's GoToAssist remote support software - it's a legitimate tool my company (among many others) use to do remote tech support. That having been said, NEVER let someone run you through that connection if you aren't absolutely sure who they are and why they're doing it - they would be able to use your computer like they were logged into it, transfer files back and forth, and so on.

This definitely helped me. Guy was trying to get me to log not citrix on my MacBook. I looked at this site on y iPad and told him I was  to interested and will send his link to abuse at my bank since he was trying to extort money from me!. As for now I have removed Citrix and all its extensions from my MacBook and moved them to trash and emptied it. I have also removed Chrome and Firefox through which many breaks occur.

Any thoughts for anyone if these guys get into your computer with Citrix?

You should erase and reformat your hard drive, then restore your computer from a backup made prior to when you allowed them access. Change your passwords and other critical information also. You don't know what software might have been installed. If you paid them by credit card, contact the credit card company, and close out the credit card.

Definitely helpful and they were not able to use Citrix because Safari blocked them and they tried to get me to use Chrome. Which I had on my MacBook

but did not have open.

When they realized I was to not going to fall for them they hung up immediately.

Hello i realized i was being fooled right after i enterd in their support key on fastsupport.com so i never installed the citrix, and hung up on them. Do you know if not installing it prevented them from getting in or were they already in once i put in the support key?

If you never installed Citrix. you should be okay.

Nearly the same thing just happened to me!

I received a call from a man claiming to be from "Windows Technical Support Group" or some nonsense telling me that there are Nigerian hackers doing illegal ***********-based things on my network. He then proceeded to tell me to go on www. fast support .com, I followed that instruction but then began to get suspicious when he asked me to put my name into the box, i exited out and googled if fast support was real and safe, then I saw this & I hung up on the man and he called me back about 5 times until he got the hint that I did not want to speak with him anymore.

Thank you to who posted this because I could've had a real hacker on my hands.

Much appreciation<3

Yes , You are right this type of issues are almost occurs in Window commonly. They are the scam tech guys who want to sale their subscription to us. So Beware all

I'm a sucker that allowed this to happen. It only dawned on me that it was a scam when he asked to purchase a 1 year/ 2 year license. But as he was providing 'tech support', I noticed he had gone in the terminal and was viewing all types of code that I'm not familiar with. This happened for about 5 minutes. When he was done that's when he asked about the $400 service charge.

What could he have accessed? I have already changed all my banking username/ passwords. Amazon, eBay, Paypal, etc.

I also initialized my hard drive and reinstalled system software. Upgrading to Sierra now.

Should I still be worried? I installed Malwarebytes as instructed by some of the threads here and nothing came up. Crossing my fingers that nothing will come of it.
