All donwload files corrupt!!!

I have been on the internet since first years of it but have not seen such a thing!

Theoretically FTP application over TCP layer should guarantee correct file downloads. The same with http downloads but since two days ago all the files (small from 1M Up to 10M) I download , are corrupt!

Both in home and in the office! I have also tried 2 different ISPs which use completely different medias (one over fibre , the other over satellite). I am using 56K USRobotics modem.

The only thing I suspect is the Norton Firewall version 2001 (I use this because it does less analysis on packets and therefore creates less load on my computer) which I have I always update it.

Is it possible that a firewall like Norton changes packet contents etc?

Or perhaps it is a new virus for ""Windows Perfect Operating System!!".

Have anyone seen such a thing?
