NT Kernel_System has changed since the last time you used it.

I have Symantec AntiVirus corporate edition v11, and the Network Threat Protection has been popping up lately with this message:



here is what i copied from the text it shows:

it asks me if i want to allow it to access the network, and i click No because i have no idea what it is or why it wants to access the network.

it seems like it randomly pops up, or whenever i turn my computer on.

any help as to what this is and how i should go about dealing with it?

thanks everyone.

Re: NT Kernel_System has changed since the last time you used it.

ntoskrnl.exe is a critical process in the boot-up cycle of the computer, that's why the warning pops up whenever you turn your computer on. The change can be due to a recent update. If you want to put your mind at ease, you can have it scanned here or here.

On top of the page there is a field to add the filepath, copy and paste this filepath:

C:\WINDOWS\system32\ntoskrnl.exe

Then hit Submit
The scan will take a while before the result comes up.

Re: NT Kernel_System has changed since the last time you used it.

ok, so i did the scan at both websites, and they both found nothing.
so the next time i get this message popping up, should i click Yes to allow it to access the network?
