I hope somebody can address this problem. I get Flash-based ads every few
minites that pop up on top of anything on screen. They have a small 'close X'
box, but when closed, they freeze the machine for about ten seconds. They are
very instrusive. I can't find the source or any files to delete this adware.
Are others having this problem? Can anyone suggest a fix?
