How to close the AdSense account

It is highly unlikely that the old (and I believe now-fixed) insecure-cookie problem described in that link is anything to do with it. Can you please describe the effects you are seeing in more detail?

Clicksor are an online ad company of generally poor reputation; it is possible they might be redirected to by some kind of spyware. Check your machine is clean.

If you are trying to block ads.clicksor.com in your Hosts file, the above won't work. You need to list the address first and then the hostname (not full URL):

0.0.0.0  ads.clicksor.com

Here is what worked for me.

1. Log in to your AdSense account. In the upper right side of your AdSense account, click on the cog or gear. A dropdown will appear with four selections. Click the top selection, which is Settings.

2. Once in Settings, the left side menu will change. In the left side menu, click on Access and Authorization. This will open a submenu. In that submenu, click on Google Analytics Integration.

3. Now you will see displayed all of the Properties you have in your Analytics account. In the upper right hand corner you will see the word Link. Click on Link.

4. This will open up your Google Analytics account in a new tab. It will take you directly to the Link Adsense page in your Google Analytics. Now when you click Link Accounts, it won’t take you to your AdSense Account, it will display a dialogue box asking which Google Analytics View to link with. Select your View and click save.

Your AdSense and Analytics accounts should now be linked.
