I pushed WPS button on modem not knowing what it was so I did research (which I probably should have done first) and discovered that I may have made myself vulnerable to a "brute force attack". Well anyway I don't know if it is coincidence but now my firefox browser wont let me access certain websites like my email or play utube videos and I am getting "You are not secured". My other browser "edge" will let me. Further research while trying to find a solution to FF browser says certificates might have been changed by a third party and just waiting for me to allow them to be recognized thus letting them into my computer/network. How close would a device have to be to what I am assuming is being recognized by my modem/Wi-Fi. and what I am also assuming access to the info on my laptop. So now I do not dare to try and get to my financial institution website on either browser. How can I tell if I have been compromised? If I take my rented modem/Wi-Fi and trade it in for a new one with a new network name and password will I be secure again? Does that make sense? Like my name says I am not computer tech savvy. Would greatly appreciate and thankful for any help.
