The avast adblocker (“Powered by AdBlock PLUS”) was available for a while, as part of avast 8. If you had this adblocker on your system, and then installed 2014 (without running the avast8 removal tool to fully eradicate its folders), you might find — as I did — that this old plug-in “survived” the update process. So that’s why, under a current 2014 version, you may still find the adblocker on your system. But on your reformatted system, for which there was a “clean” installation of 2014, the avast adblocker won’t be there. However, it’s a simple-enough matter to download/install the full AdBlock Plus program https://adblockplus.org
[Note: There are separate versions for each of the supported browsers. So for example, if you use both IE and FF, you’ll have to download two versions of AdBlock Plus.]
Hi, we ceased to provide avast! AdBlock because it was draining our (human) resources and provided barely any additional value over classic Adblock Plus. Thus we decided to let it go and focus on other things.
