Microsoft edge

I normally use the Google Browser but a few minutes ago I clicked on the micro soft edge, but instead of opening up it said Security Alert  RDN/Trojan!055BCCAAC9FEC infection it wanted me to click on this to fix it. I tried to click on the "X" to close out the window and it would not close.  I do not know how it got past my Norton home premium, so I clicked on restart, then opened my Norton and came to this screen. Is this some kind of scam they were hoping I would click on this so they could steal my info?  Please help me with this.  Gary
