Ok. Hypothetically, say someone that I know has a friend that used TDS-3 and also uses Shareaza to download music and programs via bit-torrent files and P2P. Of course that individual only downloads songs of music and programs in which they already own the CD, thus not to violate any U.S. copyright laws. Anyway, they scan the files using NAV 2004 Pro as soon as they receive them and periodically run Ad-Aware, Spybot Search & Destroy, and TDS system scans in an attempt to stay away from nasties. Also, they are behind a Zone Alarm firewall. How safe are they behaving in this manner? Thank you for your expert opinions.
