Just today, I was going to check my bank account via "Bank Mode" on Avast! Secure Browser, but for some reason, it said there was "my connection was not private" when I went to the website (Tompkins Trust Company, to be exact). For precaution, I did a Network Scan with Avast! [Free Antivirus], but it says there were "no vulnerabilities found.
And just a few seconds ago, I checked it out once more (again through Bank Mode), but I was able to get to it no problem.
I honestly have no idea what this means, or if it's anything I should be worried about.
