I believe this, and npEpicUpdate3.dll should not be allowed on my laptop computer (Windows Vista sp2). I tried to install Epic Browser a few days ago, it did not work, and my Firefox ESR browser showed an item npEpicUpdate3.dll, Epic Privacy Browser Installer as an extension. Also, AdwCleaner v 7.0.6 found two Registry items, one of which refered to "Epic"; both items named as "adware.pcoptiomizer"; and I allowed AdwCleaner to remove these items.
I still find there is npEpicUpdate3.dll C:\Users\nameOfUser\AppData\Local\Epic Privacy Browser\Installer\18.104.22.168 on the machine.
I believe I should be allowed to remove this simply by deletion, but just to be sure, I ask HOW TO DO IT?
The computer is otherwise behaving normally. Firefox iESRtself has been slow for several weeks, long long before trying to install Epic Browser; and Ice Dragon, similar to and based on Firefox, behaves faster than Firefox; and Opera is faster still. Otherwise, computer behavior is good.
