[Brazilianboiii]

I have tried many different Media players through my life.
I first to used Windows Media, although i got to a point when my computer wasn't able to play any avi or ANY video file corretly, i only recived the audio but no video.
Then i swiched to Itunes, which worked great for Mp3, although can't play avi [quicktime]
Finally i used Winamp Media player, it wokred for my mp3, and avi PERFICTLY, although i came to this day, in which a trogen came in my computer, i uninstalled winamp, reinstalled and deleted the trogen [the trogin was found in (C/Program files/winamp/), but strangly eough, when i deleted it and uninstalled winamp, it was gone...then when i Re-installing winamp it came back! Very strange] I don't understand! if someone could either tell me a Media player that plays at lest BOTH mp3, and avi or help me with my problem with Winamp and this strange trogen

any salutions?
please help?!
