Hi folks. I'm still running Nod32 AV version 3.0.621.0. I'll wait a little while before considering upgrading to version 4. Usually, the update messages Nod32 generates (I'm talking about the 10 or 15 second message window that appears in the lower right-hand corner of the screen) pertains to virus signature updates. But, the past few days, I've noticed my Nod32 generating quite a number of "Program Module updated" messages in that window. What does that mean?
