NP, I do tech support on Reddit from time to time and understand, you never know the knowledge level of the other person. Best to assume none until proven otherwise
I have another piece to the puzzle. It's definitely Opera that's setting these cookies. The list has grown since the original post. It now includes two sites I went to earlier this evening in Opera.
Thinking maybe the files were still locked by the system, even though Opera was shutdown, I rebooted and ran CC, no change. I then booted into Safemode, ran CC, no change. I'm going to go through every Opera file/folder and see if I can find them. I'm also going to post this on Opera's forum and see if anyone there has insight.
