Suddenly this morning IE8 has started crashing on opening, whether opening it directly from the Start Menu or using a saved bookmark. The "Internet Explorer has stopped working" box comes up, I click "Close Program", an Application Error box then appears with "Application Error: Exception EAccessViolation in module ShellEh428.dll at 00008A08". I click "OK" to close that, and then IE8 proceeds to open and display normally. Then, within the same session, the same sequence of errors outlined above occur each time I click a link or try to open a new blank tab, etc. but IE8 doesn't actually close after clicking through the error boxes.
Another "new thing" is when I use File > Send > Shortcut to desktop I now get a confirmation box I have to click in order for the shortcut to save, which I never had to do before. I tried resetting my IE settings to default which didn't help.
The only thing that's changed on my system is a Windows update for Defender that installed this morning. I used 2 different restore points to go back a day or so and it didn't make a difference.
