Hi -

First...what version of Bitdefender 2009? Is is one of the suites?


BitDefender Total Security 2009
BitDefender Internet Security 2009

Or the standalone BitDefender Antivirus 2009?

if a suite (one of the first two), you don't need another firewall.

Second, it's never too late to run the NRT. If Norton was once on the machine, and the NRT was not used, go ahead and use it anyway.

Some software firewall options available here:

That said, with the advent of highspeed internet, most machines are behind a router with a hardware firewall. It's all I use for mine, that and the native firewall of XP or Vista.
