avast5.0.377 – Computer hangs on using avast User Interface

My Computer hangs when I use avast5.0.377 User Interface and when I try to Update it manually. Sometimes I can successfully access the complete avast5.0.377 user interface and update it. I think that avast auto update is successful every time. This thing never happened on previous version avast4.8.

How can I use avast User Interface without hang?

I uninstalled adobe Flash Player and reinstalled it.

avast5.0.377- My computer not hangs using avast User Interface after reinstalling Adobe Flash Player10. There is no problem in User Interface after reinstalling AFP10.
