Blocked By Adware

I just wrote a new journal entry, but it's gone.  I should have backed it up to a text file like I usually do, but I got absorbed in the topic and didn't.  Then I accidentally rolled the cursor over that ad space in the lower left...and poof!  The screen went to black and I lost the entry...no little x in the corner to shut the ad off, no video of some product, no nothing...just black screen.
I'm tired now, and I'm not typing a new entry.  Maybe tomorrow I'll get back to the journal...sorry, but this is not my fault.  Adware is badly written software thrown together quickly for an easy buck...and it often jams things up.  I'm going to go lie down.
