As Eddy noted, mail protection in 4.5 works automaticly. So can setup your account as if avast! is not installed (no 127.0.0.1, put your real pop3 server here).
Anyway that does not mean that the old way shouldn’t work too. So there must be some other problem. Please re-check your account settings.
In any case your ISP is probably not involved.
