I had a chat with a programmer on another forum,and sorted out the malware problem.

Then I did a clean install of Shareaza following instructions found here. When I setup the connection,I need to "enable UPNP connection devic setup" as I have a router. It worked fine the firsts time,but not when I started it again --it keeps unenabling UPNP ,unticking the box in the connection screen.Connection test then shows I'm behind a firewall.


I haves a static Ip set up and an exception for Shareaza on my Firewall.
