There has been a tracker program with an independent 'Window' obstructing access. No lie. It's a high level 'program' not a virus.
I didn't detect it until I started to shut the computer down. The independant window appeared for only a brief moment and I wasn't able to capture the address. I am convinced it's on the laptop in memory somewhere so I'll take it for evaluation.
The strange part was the windows I had opened appeared and disappeared and reappeared at will. It was strange. I think they were being viewed by someone else whenever I couldn't see them on the screen. I wasn't doing anything significant except a little blogging, but, there was someone else within the connectivity between my laptop and the net.
Just thought I'd pass it on.
