Seems difficult to find exact info....

Egad...that didn't help any.....

about two-thirds of the way down that page there's an entry about "Win32 salty" ...which is claimed to be a virus... usually sent as an email attachment.
...Perhaps someone's found another way of distributing it.
Ah ...guess I should've read the whole page.
I just scanned over it till I found the bit I was looking for.
Oh well, I had the best intentions ...and it's all I could find on the subject. What you said in #1 is true ...hard to find anything about it.
Good luck, Po'
Ah....I'd come across 'updater.exe' having potential issues in the past...but not with the firefox ver ....so it looks like the other ones' history caused the false Pos with firefox's.
Maybe Avast is almost as iffy as Norton...which is famous for false positives...
BX ...that comes from the site I linked to above. If you read the rest of that page, you'll see that the information there is of a somewhat dubious nature ..as Jafo kindly pointed out.
