Worried about backdoors

[KronoLeginaire]

Hey all,

Basically I am worried about backdoor trojans that may exsist on my system, that Norton has not caught. I know of the numerous ways to prevent them and to keep them from starting up by skimming down my startup services, but it would be nice to know what programs are potential threats because sometimes I get viruses out of the middle-of-no-where, they keep comming back w/ increased network activity, one time one of the attacks occured, i unpluged my eithernet cable and it stopped.

Please help, thanks.

-Yes NAV is totaly up-to-date.
-Yes, I use ZoneAlarm (sometimes)
-I have already ran a Online virus Scan
-I already changed my NICs from the last networking problem I had.
