Adblock Plus with very limited options is part of Avast. It does not have the same subscriptions unless you add them. Yes the Avast’s paid products sandbox is different then Avast’s free sandbox. But it still cannot full virtualize your browser like Sandboxie. But lets not veer off the beaten path and hijack this thread. Thanks.

Here is a side by side comparison.
