It didn't hijack my computer, but they talked me into switching browsers as my default browser so I switched to edge. That is when everything quit working, I could no longer log into my bank account, I could no longer download anything ect. I switched back to Chrome and now everything is working again. The main reason I switched in the first place is that they said edge used a lot less resources. That may be, but if nothing works using edge whats the point!!!!
