Ver 5 error message

I just switched from using AVG for years.

I have the Avast 5.0 Internet Security program.

I also use an ancient newsreader called X-news because it is good for text newsgroups such as politics.
Since installing Avast when I try to connect with the newsreader I get an error popup that says:

481 SSL access not allowed.

Worked perfectly before the change.

How can I fix this?

My newsreader connects to Giganews provider.

Everything worked fine before the change to Avast.
