Let's see how this goes....I got on earlier this afternoon and was able to post. Last night, I bought a new "system protection program" that I used to have on all of our computers. I ran a scan with it and it did catch something that was allowing extensions from my browser. I'll see of this will post. If I don't get anymore notifications, I'll assume it's been repaired, but since I use this computer for bill paying, I still may take it somewhere to make sure it's disinfected, not compromised, or hacked.
