I'm from China!Avast is a very good antivirus software!!
It's too slowly to download the update!
I can't bear it.
And open your website is also very slowly.
I think that is something outside of avast's control, I have a dial-up connection and the incremental updates are fine as is the access to both avast.com and the forums.
The VPS updates are as has been said incremental so the download is much smaller than many other AVs. Typically the VPS update for me is under 25KB in size.
Are you downloading the complete VPS400 file from the website (
avast! VPS Update - Manual Download) or using the programs auto update function ?
