I don't see any trace of Downloader.Istbar... if it is in your temp inet files, have you deleted them? You can download Ccleaner and let it do it for you..

A couple of things in your log..

C:\Program Files\ZUM\task.exe
O2 - BHO: ShowBarObj Class - {79A002FB-C126-462D-B4A7-81D6B42D1666} - C:\Program Files\ZUM\acrbat.dll

seem to be related to a "Commander Toolbar" or something similar. If you don't want it, I suggest uninstalling it from Add/Remove programs, reboot and run another HijackThis log to see if they are gone.

Thanx Byteman, I used CCleaner and that got rid of the trojan. For some reason I thought getting rid of a trojan would be alot harder!

Thanx again.

I dont have any commander toolbar in the add/remove programs...
