The popup with the telephone number you are seeing is the malware/adware issue on your computer. It's a new wrinkle on the cold call scams and the fake antimalware programs that were previously being installed on computers that
we have heard about for years. Now the scammers are trying to get you to call them....
Instead of calling you on the phone they've managed to get an ad into your browser (probably during a freeware download) and if you call them then they'll want a large fee to fix your computer or they’ll try to sell you
an antivirus program (one that may or may not work) or some other unneeded service. It's nothing but a scam to get your money and credit card info. Some of them use what appears to be a local number but in reality the scam may be from a country which will
not cooperate with law enforcement agencies trying to identify the scammers.
Here's some articles about the phone scams - circumstances are similar but the scammers are now using fake ads to get you to call them:

Once again let’s look for malware on your computer:
Download and run Adwcleaner and Malwarebytes Free.
See: http://www.bleepingcomputer.com/download/adwcleaner/
And
Go to http://www.malwarebytes.org/products/malwarebytes\_free/ and
download, install, update and run the free version – just follow the prompts.
And/Or
Try the Kaspersky Virus Removal Tool: http://www.kaspersky.com/antivirus-removal-tool?form=1If
necessary you can download the program to another computer, put the removal tool on a flash drive and then run the removal tool on the infected computer.
Did you run Hitman Pro (trial version) as recommended in the previous link? Very surprised it did not identify and eliminate this malware.
You may need to completely uninstall Chrome (do not save any settings) and then install a fresh copy.
And you may need to revert to IE-10 from IE-11 - if so, see the

Alternatively - - - you may wish to try System Restore (that may or may not eliminate your issue and remember to be sure you’ve backed up any documents, pictures, music, etc you wish to save before
trying it). Or - - - you can reformat/reinstall the operating system, restore to factory settings if that’s an option with your computer or take your computer to a repair tech.
Good luck…
