Hallo LandzDown Forum, and thanks for the nice Welcome !

My wife, and I have got a PC with Windows Vista and Norton Internet Security 2007 on, as a 90 days trail.
Last week did Ingrid's period expire, and it can not be updated, what do not surprise us, as one is supposed to buy the product...
But - Can it scan prober and still protect now ? Is it safe to use, for some time (Guess there is not new Virus every day).
Or is there a Risk ?
And -
If one decide to get a free Anti-Virus Program - What are best to Vista, who is using Firefox 98%
:firefox:
What is best ?
Greetings
