My Outlook 365 renew button kept popping up as I was close to the end of my one year term with Office 365. The first time I clicked on it live.com opened as expected. In addition, 54e.com opened in a 2nd tab of my default browser. I closed that after disabling all addins and extensions except Avast.
I opened Outlook again and then clicked on the renew button. Live.com also opened and 56e.com in the 2nd tab.
I am not an antivirus expert, but am quite technical and very meticulous about security on my laptops. Just wanted to share as I could find nothing about this on the internet.
