That link you provided for resetting your browser is very good.
However, I have recently found this does not solve the issue in certain circumstances. 

I have found hidden Windows .bat scripts inside the  C:\Program Files (x86)\Google\Chrome\Application that changed the start page of the Chrome browser even if you reset the browser following the excellent Trendmicro link above.

Here is a copy of the hidden batch script I found in the Chrome program folder that I uploaded to Gist. 
(I changed the file extension to .txt to make it benign)

To fix this problem you must enable "show hidden files and folders" in Control panel/Folder options/View to be able to see these batch scripts in the folders.

Delete the hidden chrome.bat, firefox.bat and iexplore.bat from their corresponding program folders.

You will then have to delete any shortcuts you have to these internet browsers on your desktop and task bar and create new shortcuts from the REAL chrome.exe in the C:\Program Files (x86)\Google\Chrome\Application folder.
(Do the same for Firefox and Internet explorer)

NEVER let these fake "Microsoft" support scammers take remote control over your computer!
I let one of these scammers remote access my computer (The scammer did not know it was a virtual machine) and he uploaded a batch script called "antivirus.bat" to my VM and executed it.
It changed all the start pages of the internet browsers on my VM in the registry and created a Visual Basic (.vbs) full screen pop up that said my machine was infected.
I uploaded it to Gist as well and changed the file extension to .txt to make it benign.

Also, the OP said he was not able to close his browser.

You will need to run the Windows Task manager by typing taskmgr.exe in the Start/Run box or by holding down the Ctrl-Alt-Del keys to pull up the Windows task manager.

Use the Task manager to kill all instances of open internet browsers.

Next, open the offending browser and delete all the history from the cache so it does not pop up again.

Thank you for the kind comments and suggestions sloshnmosh1. We really appreciate it.

In reality, the computer doesn't really have any form of infection whatsoever. Please do not believe it.

We will make a report of it as well so if you have the number on the page, you may give it to us.

If you need additional help in cleaning up the computer as well, feel free to contact our support channels on this link so we can assist you by checking your computer 

I hope this helps. Feel free to let us know for further concerns.

Have a great day!
