wow dude, rough start
Anyway: You were new also, noone is saved by being new.
OK:
1. ANYTHING may be virus, even game rips, you never may be sure. They maybe have adden few "trainers"(viruses).
(BTW: i downloaded Mortal Kombat 4 from KaZaA and the trainer was with CIH virus :P )
2. OK, MAYBE i forgot to mention that i have heard a rumour about that Lite has spyware.
3. I hate you, screw you.
