About Avast web page!

I view update page information , but when load complete.
Still has data to computer? (I use ZoneAlarm on green line not stop.)

Sorry I don’t understand the question, can you expand ?

Are you saying that you can’t update but ZA allows access to avast.update ?

I view http://www.avast.com/eng/vps_history.html
by Firefox.

When Firefox show “Done”
But Firefox will load unknow data.

I see this all time at view one by Firefox.

But Firefox will load unknow data.

What is this unknown data ?
Is it the format or layout of the page or do you think something eles is being downloaded ?

I use firefox as my default browser and no problems with that page I view it regularly.
