!Update.exe Trojan

Hi there

I keep getting the following trojan when I boot my system up:

Trojan horse Downloader.Generic.TUC, file name: !update.exe

There was a similar thread posted by bolun and I have followed all the instructions given in the thread. I attach the HJT log. Can anyone help get rid of this annoying trojan??

Many thanks in advance for any help give!

Jason.
