Might be a noob question...

Ok, I just installed Nod32 on my computer and everything was fine for a while, but now my port all of a sudden isn't forwarded? Any help?

Nod version is 3.0.657.0

uTorrent is 1.7.7

You could try going into Advance setup and adding uTorrent.exe to your exclusions list.Not best option but see if that does anything.
Did a little digging and it seems F33NY that you are not alone in having that problem .
It's Nod almost definitely and there's no known fix.Seems you could do as I suggested or try reinstalling Nod or revert to an earlier version.
