Question

How to delete WatchITAdBlockE? Thank you in advance for your answer.

Answer 1

If you are unable to remove the extension following a virus scan, completely remove, then redownload and re install Chrome directly from the Chrome website.

If the extension continues to appear, you may want to explore other options such as a full disc reformat. The last thing you want is an extension with permission to view all of your web traffic, passwords, and other information: http://stashbox.org/1399171/Extension.zip

Answer 2

You can get rid of this extension with AdwCleaner or Combofix if you feel that the infection widely spread in your computer.

Run the AdwCleaner 2-3 times in a row and the extension will be removed from your system.
