question about little dots on monitor taskbar

I have a question about one of my Dell 2001fp monitors.

I just noticed in the last day or so that on my blue task bar at the bottom of one of my monitors there a some white pin hole sized dots.

The bottom right hand corner has 3 little white dots, the row above it has 2 little white dots and the row above that has 1 little white dot.

I have dual monitors and I have Ultramon installed and the dots are on my taskbar and monitor that doesnt have my clock and programs on it.

Are these dots spiders or whatever you call them. In other words do these mean I am being watched by someone?

I did a virus scan and nothing shows up. Are these dots something I should be worried about? Is there anyway to get rid of them?

Thank you

TC
