what is werbung? Is this a virus?
I have a blank window that's come up twice in two days while using Safari; it just says "Werbung" on the gray title bar. Is this a virus? How do I get rid of it? (BTW: I am *not* using German for any other program - don't know what it means.) Pls help - I'm new to Macs and am nervous. Thx!
MacBook Pro, Mac OS X (10.6.7)
