Activity Log in Norton AntiVirus

[titilucky]

I was checking my activity log in Norton AntiVirus and found the following entry under "System":

"Internet Worm Protection setting "Port Block Allow NetBIOS change.  Old value: 1"

This appears every day.   What does that mean?  Is it something bad and, if so, how can it be corrected?

Thanks.

Judging from what is stated there, it seems logical that Norton is blocking the NetBIOS ports in order to make certain that no harmful malware can connect to them.

NetBIOS  commonly communicates on ports  137, 138 and 139. If your network  or computer  has a firewall  setup  that blocks any of these ports it is likely warning messages  will be received when your computer communicates with another computer that utilizes NetBIOS (for example Microsoft  Windows). To prevent these errors  or warnings you must provide access  on these ports.

In matters of good and bad. It is a good thing.
