You need to go into your settings as the adblockers wouldn't be down to Grabpoints. They must be set up on your computer. I don't use adblockers but this is how you disable them on Chrome.
- Click the Chrome Menu icon from the browser toolbar.
- Highlight the Tools menu, then click Extensions from the sub-menu.
- Click the Trash icon that appears next to the Adblock Plus entry.
- Click Remove once the confirmation message appears to effectively uninstallAdblock Plus from your Web browser.
