BleepingComputer is an excellent site. As a staff member, I personally can vouch for it. What you don't have access to are threads where staff members discuss new infections, new variants of infections, new tools, changes to new tools, etc. It's one of the sites that anti-virus/anti-spyware apps rely upon for their updates.
The sites Nocturnal mentioned are also excellent. As a staff member at those sites, I can also vouch for them.
