pop up message won't stop
For the past week I have been getting a pop up message everytime I log on, open a message, go back to the board message listing. The pop up is titled Security Warning and asks " do you want to installl Adobe Flash Player installer." I click no each time and it goes away until I go back to the message listings and it pops up again. Click no again and it goes away until I open a new message and it pops up again. I suppose if I clicked yes it would go away, but I don't feel I should have to.
It does not happen on any ohter site. Any idea on how I can stop this from happening?
