Q: Safari

Don't call that number, it's a scam.

Go to Safari menu (At the very top right side of your screen next to Apple icon), choose "Quit Safari"

press "Shift" button and while holding this button on your keyboard single click on the Safari icon on your Dock.

You also need to use Adwaremedic. It is a tiny tool, which will remove the adware within several seconds. You can download Adwaremedic from this website: http://www.adwaremedic.com/index.php

You can also remove the adware manually using the steps provided by Apple: https://support.apple.com/en-us/HT203987

Also, I believe it would be a good idea to install AdBlock.

If you’re on a Mac, choose Force Quit from the Apple menu, close Safari, and then launch it with the Shift key held down. If that doesn't work, temporarily disconnect the computer from the Internet and/or click here and run Adware Medic. You may need to download it from a different web browser.

If you’re on an iOS device, click here and follow the instructions in the first paragraph of the last section.

You are welcome.

For others finding this discussion, there is absolutely no reason to download anything to solve the problem.

It's not malware. It's a Web scam that only affects your browser, and only temporarily. There are several ways to recover.

1. Some of those scam pages can be dismissed very easily. Press the key combination command-W to close the tab or window. A huge box will pop up. Press the return key and both the box and the page will close. If that doesn't happen, continue.

2. Press and hold command-W. You may hear repeating alert sounds. While holding the keys, click the OK button in the popup. A different popup may appear, which you can cancel out of as usual.

3. From the Safari menu bar, select

          Safari ▹ Preferences... ▹ Security

and uncheck the box marked Enable JavaScript. Leave the preferences dialog open.

Close the malicious window or tab.

Re-enable JavaScript and close the preferences dialog.

4. If the Preferences menu item is grayed out, quit Safari. Force quit if necessary. Relaunch it by holding down the shift key and clicking its icon in the Dock. None of the windows and tabs will reopen.

After closing the malicious page, from the menu bar, select

          Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data

to get rid of any cookies or other data left by the server. Open your Downloads folder and delete anything you don't recognize.
