This se.dll thing will not go away it just keeps coming back. My OS is ME, I've got AVG 7 and spywaresweeper. I first got this a few weeks ago and ended up formatting only to get reinfected the next day

from a totally different site that I have visited for years and never had a problem with. Here's what happens:
AVG pops up with a virus warning about se.dll, I tell AVG to delete it, it does.
Spyware sweeper warns me of a homepage hijack, I restore to original.
I run Hijack This, check unwanted entries, including no name BHO and fix.
I then boot up in safe mode with system restore off, run AVG and delete the randomly named dll in windows\system.
This seems to get rid of it.
Initially se.dll would activate everytime I opened iexplorer until I deleted an exe in the internet explorer folder. It would also activate everytime I tried to add\remove search assistant uninstall.
After taking the above removal steps it activated roughly every two days regardless of what programs I am running, this I could live with, but now its back to activating every time I open iexplorer.
here's my hijack this log:

I also check my msconfig start up programs and have seen nothing suspicious. There must be something somewhere on my computer causing this but I can't find anything. I've searched through loads of help forums and found nothing that helps. Please help me get rid of this bloody thing!
