father-in-law has asked me to try and get rid of a trojan downloader on his laptop.i have used avg/trojan remover/a-squared and a registry cleaner.i think it's gone,but fifeflyer suggested i post a hijackthis log.
another persistant problem is his dial-up connection to bt yahoo is lost when outlook express tries to connect - i'm not sure if the problem is related to the trojan.the trojan was present in system32 folder as'append.dll'which seems to be gone
thanks for all help
