Accidentally downloaded a virus

I unwisely wound up downloading an app that has infected my Microsoft Edge browser (oddly, the other browsers work just fine).  Whatever the case, whenever I enter something to search, I initially see an address starting with "findsearchtools.hub.com."  I then get an AVG pop-up saying, "Threat secured.  We've safety aborted connection on www.safebrowse.io because it was infected with URL:Phishing."  

The address screen then reads an address that essential translates to www.safebrowse.io

Can anyone give advice on how to remove everything causing trouble?
