Solved how to find/delete GameZooks pop up advertisement Windows 7 , Chrome

[lizzrd]

I have three kids 5,7,9 years old that have up to this point been very good on not clicking/opening anything unfamiliar on many different sites. I have my settings for internet set at medium high. I also have Norton internet security on my machine, and have not had any problems in a couple years. I could not find this gamezooks anywhere on my machine. My last tries i used Advanced Uninstaller Pro 11 to find/delete/or clean to no avail. Any help would be much appreciated...
... it just popped up after posting this on this site.

Hi and welcome to SevenForums,
Most likely a browser extension inside Chrome
Open Chrome and click on the 3 horizontal lines on the top right,
Click on Options or settings,
On the left column go to Extensions and review them.

Review Jacee’s instructions to run Adwcleaner here post #7,

On the BleepingComputer site use the button that looks like this,

You can use these free tools to see if they find anything,
Manually Update them before running full scans,
Try not to use your computer while the scans are running, (one at a time of course).
See this tutorial on how to download and run Malwarebytes,

Also use the Custom scan option not the Threat scan,
Please Do Not clean/ Delete or Remove Any detections before posting the scan results first before review especially Malwarebytes,

This one is the longest up to 4 hours, the others are only about 45 minutes,

Also, check the shortcut for Chrome you are using (Right click properties). If it has anything after the "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" then delete that extra part.
