Looking at your screenshot, you also have Kaspersky installed, I just wonder if this also is having an impact. Multiple AVs on a system at the same time isn't a good idea as they can conflict.
As Raeken said you aren't in Safe Mode when you ran the Avast Uninstall Utility. However, previously you could launch it from normal mode and it should reboot into safe mode and run in safe mode, this doesn't appear to be happening. You would have to boot into safe mode manually and run it as Raeken said.
