Today has been a bad day.
When I first logged in today, I got a nice big "Avast most make an update" dialog.
Then I ran a program of mine, and noticed the window had a 1- or 2-pixel red border around it. A few seconds later and the window closed mysteriously. Then I tried to run it again, and got a "system service exception" BSoD.
I restarted, and told Avast to scan my computer. It said it was at about 10% progress after an hour, even though it had scanned 50% of the used hard drive space. Weird measurement or something.
While that was going, I decided to do some more coding on my FPS. I went to test some of the new code I wrote, and the build process took way longer than normal (it delayed on the first step), and when it finally ran the game window had the same sort of red border around it... and then closed. I tried again, and the same thing happened.
I tried to run Firefox from the task-bar (or possibly from the desktop icon?)... IIRC at some point it told me it couldn't because an instance of firefox was already running but not responding. This I'm not entirely sure when it happened.
So I tried looking through the Avast UI for settings that might be relevant. The UI became non-responsive. I tried to ctrl+alt+delete it, but the ctrl+alt+delete screen wouldn't appear! I tried to close MSVC so I could see my desktop, but MSVC was unresponsive. I tried to run Firefox from the start menu, but then the start menu/taskbar (and presumably all of explorer.exe) became unresponsive.
Ultimately I had to restart by holding the power button for 5 seconds.
Help me, HLP!
