Greetings, this morning after logging into my computer I was immediately prompted by Avast, if I wanted to set Avast Safezone as my default browser. I noticed a new Avast logo on the screen, a yellow circle with a ship’s stirring wheel inside; I never seen such logo. In addition, I continue getting a popup screen reading " another program on your computer would to modify Firefox with the following add on; Avast online security 10.3.3.13 location c:/program files/avast/webrep/ff
Your assistance is greatly appreciated as I’m not aware if this a virus. Thank you!

Thank you so much for the quick reply, I feel more relaxed. 
You’re welcome.
