trojan download dropper

jeg fik en besked fra AVG om at der var en mulig trojan download dropper. i windowsmediaplayer...
samtidig forsøgte WMplayer at komme ud igennem min firewall!!
og kommer ogsaa med fejlmeddelser om at en anden trojan horse er i mine temp. internet files... så jeg har slettet alt temp.!(i explore/instillinger/slet cookies/internetfiles)
AVG forslog jeg skulle køre AVG og fjerne det..men AVG finder ikke noget...,
og jeg bliver ved med at få meddelesen om trojan`
jeg har kørt ad.aware og spybot!
og her er min hijackthis log:
