overrule NAV decisions

Greetings:
OS: Windows XP+SP3
Norton AV 2012 19.2.0.10

How can I overrule NAV decisions about suspected virus,trojan etc. (except for excluding programs)?
Couldn't find anything in the settings, and I'm quite sure (and willing to take the chance) that some of the exe files removed after a scan are non-malicious.

Can I restore removed objects from the quarrantine?
Thanks
