Is there a way to proxy chain Avast with another proxy i.e. browser->Avast->proxy?
What proxy ?
Have you tried a forum search for the proxy you want to use ?
It may have been discussed previously.
Should have know better… :-[
It was Privoxy and yes it was discussed.
Yes, it is possible. Please see this FAQ entry: http://www.avast.com/eng/my_isp_wants_me_to_u.html
I trust that you are now up and running with privoxy and web shield.
There really is a great deal of information on the forums ;D
