Hi
chemist. I can't remember exactly what it read, though I do remember it was an AVG pop-up and stated "possible threat" and "trojan agent". But I haven't gotten an alert since I mentioned it.
Also, I did a full scan using AVG as you requested, and it came up clean with the exception of some warnings (no infections though). I took some screencaps of the results:
Screencap 1
Screencap 2
And thanks for the clarification about the anti-spyware programs!
