What Is Weknow.au?
Weknow.au and mirror of that site (http://weknow.ac/, etc.) may somehow persuade users to use an advertising search engine. If your browser shows Weknow.au instead of your default search engine (Google, Yahoo, Bing, etc), it may be a symptom of infiltration. Once after you used Weknow search engine, your browser starts to show irrelevant search results. Moreover, it can show you ads pop-ups. Usually, adware like this one gets downloaded with some free app or gets installed by a fake software update (for example, through fake Adobe Flash Player update). Also, Weknow can use a user’s personal data without permission. You may follow our instructions below to uninstall the adware and stop Weknow.au redirects on your Mac.
