When i disable AVAST it still remains in the background.
I must do ctrl + alt + delete to see where it stands and disable another three items to get the icon out of the taskbar and complete stopped from running.

Apart from this, a few questions arise.

Why this hyper text stripping doesn’t happen in Thunderbird or Outlook?
Why it won’t do it on another newsletter i’m subscribed to even if AVAST is still running?

Looking at it from this point of view, it can’t be an AVAST problem can it!
