Recently, i found that my computer's shutdown process takes a very long time (about 5 minutes). It has never been that before (usually only take 30sec), so i enabled windows shutdown debugging message. It shows the process was slowed down by "Stopping service: Avast Tools" and "Stopping service: Avast Antivirus", and this process takes more then 4 minutes.
I'm wondering what cased that... i have to use force-shutdown now.
