i got the same prob... it infected my helpcntr exe and firefox exe files ,,,, from what i've encounterd, this worm clings to the .exe files and disables it... and also it increases ur cpu workload of up to 100%.... therfore fatal to ur system... the only solution i came up with is to uninstall the programs already infected by it! But not yet tried reinstalling the unisntalled prog... I removed my mozilla browser and it works! the multiple threat is gone! .... :good:
