hmmm second cursor on screen

[smithers]

I'm wondering what this could mean. Twice now when I've been looking at threads on terb I've noticed a second cursor moving independently elsewhere on the screen.

Needless to say I'm a little unnerved.

I have Norton 360 and am using Firefox. Would really appreciate any techie advice on what this might mean and what I should do about it.

Thanks

Sorry not sure what that means exactly. Don't think its a form of advertising popup though as it was moving around in the middle of a thread almost as if someone else was reading it. Gave me the willies as I thought maybe someone was remotely accessing my computer.
