I have uTorrent and I am not infected with anything.
Who says uTorrent is known to be infected?
Bittorrent is not illegal, Norton even supports some bittorrent clients with download intelligence.
I never tried downloading videos but when I download a Linux distribution I can check the published CRC or MD5 hash value and can clearly see I am getting the ISO complete and untampered with.
Why would a AV program not let you use a program like that?
