Thank you very much for the reply. I don't have my infected laptop with me at the moment, but as I mentioned in the original post, I did use CWShredder (v.1.591) a few times both in normal mode and in safe mode. So the HJT log I posted is the one scanned after I had used CWShredder (as well as AdAare and SpyBot).
Did you update CWShredder before running it?
