Well.
Let me do a further explanation of my situation.
I`m changing the Antivírus of all computers from a client of mine.
This client does not allow the stations to access the internet. But all the stations have access for only a few pages that they need to work.
To do this control of wich sites they can access, he uses a proxy server that shares de connection and filter it.
Now, I need to find the URLs of auto-update from avast, so he could allow them on his proxy.
So, Mr. Para-Noid. There is no direct connections to just umark the box of proxy server. =/
In the end, seems like I can`t use avast on this client.
Tnx for your help.
