Warning! Virus on Photobucket (banner?)
I was just trying to insert one of my pictures from Photobucket when my browser (Firefox) shut down and a window that looked like an application window popped up saying I was infected and needed to perform a scan. This looked suspicious so I asked DH what AV software he installed on laptop. This was not a real application window - cleverly disguised link that would have loaded an executable if I had clicked on it! Beware if this happens to you (looks like AV Doctor)! DO NOT CLICK ON THE BUTTON IN THIS WINDOW!
I did go back to Photobucket and was able to view and insert my pics without this happening again, so most likely it was in a banner ad that ran at that particular time.
