Vista Security Center

[Ebrehe]

Hi all,

Recently I've bought a new laptop and it came with Windows Vista Home
Premium and Norton Internet Security 2007 (trial). I've deleted Norton and
installed NOD32.

Now when I look into Security center, I see that firewall is green, says
that Norton is open !!! and windows firewall is closed. Also antivirus part
is green, says that NOD32 and Norton is active!!!

What can I do? Also it seems that Windows Defender is closed. Is it a problem?

Thanks
