This past week I started getting the Did Not Connect: Potential Security Issue warning when I tried to access my email at Comcast.net. I also got the warning on my banks website when I tried to transfer funds, something I had done many times before. This seems to have started after "upgrading" to version 78.7.1 of FireFox. However, I got the same sort of error using Safari: "Safari can't verify the identity of the website xfinityconnect.email.comcast.net" The certificate shows it is issued by "AVG untrusted CA" from the country "CZ" and State/Province "Brno". Comcast told me to just trust their certificate and I was able to get to my email account, but I am getting the same warning from PNC Bank's website when I try to transfer funds. This REALLY has me worried. Can someone tell me if this is a sign I've been hacked? How can I fix this so I can again transfer funds from my checking account to other banks?

Hi

This is a problem with your AVG security software that inject itself in the certificate chain as you can see by the issuer of the certificate (AVG untrusted CA).
