I have had to do this otherwise VV slows to a crawl or sometimes stops altogether.
Clear board cookies as before. What to do next depends on the type of browser you are using, but you will need these addresses:

http://gripsky.co.uk/In IE go to Internet Options>>>Privacy tab>>>Settings>>>Sites button. In the new pane C&P the above addresses into Address of website and click Block. OK your way back to Internet Options. Still in Settings >>>Advanced button. Tick Override automatic cookie handling and Block Third-party cookies. OK back to Internet Options.Now make sure Turn on Pop-up Blocker is ticked>>>In Pop-up Settings and make sure blocking level is at least Minimum.
If using Chrome>>>Select Settings>>>Show advanced settings. In the Privacy section, click the Content settings button and tick Block third-party cookies. In the Cookies section, click Manage exceptions and C&P the addresses into Add a new Hostname. Choose Block as the Behaviour pattern. Close the panes as you make you way back to Settings and close that tab.

Now for Pop-ups in general.
For Firefox or Chrome based browsers there is are extensions known as AdBlock or AdBlock Plus. They both use filters such as Easy List or Fanboy's which are kept up to date by the net community.

In the left pane go to Tracking Protection then click on Get a Tracking Protection List online. Scroll down and Add EasyList Standard and Easy Privacy. Once they show in the right pane right click on them and Enable. This might happen automatically or you might have to close and reopen IE.
Doing all that will help with pop-ups completely and not only on VV.
