I'm not so sure it's McAffee. I deleted McAffee and installed PC Tools Firewall. The problem persists, ie I get knocked off the internet when I run Limewire. I do not have this problem otherwise.

I have a new machine running VISTA. I have Limewire 4.12.11 and Java 1.6.0_01.

Suggestions?

I'm leaving this here, even though it's a double post, just in case there are issues with uninstalling McAfee (eg leftovers remaining) which may cause problems & that BasRuiter might be able to respond to.
