Upon visiting an internet site, as you know, a window pane on the task bar encapsulates or describes the site. (For example, as I write this, the task bar's window pane below reads "BleepingComput".)
Each time I connect to a site-- any site-- and linger there, a second pane sporadically and spontaneously appears and then quickly disappears. It's difficult to detect because no new window accompanies the window pane and because it disappears so quickly. Furthermore, this phantom second pane doesn't contain any text. Although it's approximately the same size as the ordinary window pane, only a small white square, approximately a third of the pane's size, identifies it.
The secondary pane suggests some trojan's partially thwarted effort to establish a full, complete connection to a site and to open the accompanying window. Alternatively, it suggests some spyware recording my internet history.
I attach the requisite logs below. Any help you can offer would be greatly appreciated.
