This just started happening yesterday on my Asus t100 (windows 8.1 IE Metro). Just about every page I go to, I get this popup:
This program does not have a valid digital signature that verifies its publisher.
Name: C:\Windows\System32\Macromed\Flash\FlashUtil_ActiveX.exe
Publisher:Microsoft Windows Third Party Application Component
Now, it doesn't matter if I click YES or NO, it just keeps popping up over and over again, and won't let me close the window. I pretty much have to shut down IE from the Task Manager. Doesn't happen on the desktop version. I've had it happen before, but for the life of me I can't remember what was causing it or how I got it to stop (it's not a virus or malware). Any suggestions?
