Thanks for the reply. I'm just converting youtube videos to mp3. I scanned with avast. No threats found. I'm planning to download from p2p because in converting youtube to mp3, the quality that I get is not that good. My co-worker has music and they are 320kbps, quality's great. He said he downloaded it from sites that give free mp3 downloads and p2p sites.
Worms can only infect me when i ran an executable file that is infected, right?
Thanks
