This is driving me nuts. Every time my computer boots, or is awakened, I receive dire warnings that I have a variety of trojans and other malware in my various Thunderbird folders.
The problem is that the actual files were deleted long ago (usually automatically by the junk filter as they came in), but because of the nature of how Thunderbird stores files, there are vestiges of the attachment file names still there. NIS keeps finding them and either can't delete or wants to quarantine the whole inbox file. I've used Thunderbird a long time - long before I came back to Norton, so deleting my Thunderbird installation and starting over isn't an option. These files seem to be hidden in a c:\Windows\CSC\v2.0.6 folder, which I can't access. I'm loath to have NIS ignore these in case there is something real there. The problem is that I can't tell.
Mozilla and Norton need to sit down together and solve this. Saying it isn't your problem is unacceptable.
