i got a problem with the same trojan, and avast detected it but inmediately this trojan came back. no adwares, antiviruses deleted it. but i have a solution, even when my pc was infected by Startpage.IX. try to get PestPatrol, a good program to remove trojans and rubbish, this one was the only one that removed this disturbing trojan. i hope this info is useful. ciao ciao
