NetworkSolutions Consumer Insight

Hi,

Almost every time I visit netsol.com I get an invisible popup called
"NetworkSolutions Consumer Insight". I can click on it in the task bar,
but no window appears. It tries to hide but often doesn't succeed. When
I leave netsol the window remains open (which makes it even more
suspicious). It's not possible to view the source of the file in MSIE 6,
but I'm able to close the popup without complaints.

Does someone have an idea about what it's doing? Is it spying on me? Why
does it want insight in me? Does it spy on what I do on other sites than
netsol.com? I'm a loyal and happy NetSol customer but I don't like
sneaky popups like this one, it lets me think of other less trustworthy
sites than netsol.

Thanks,
Erik
