I'm running SpySweeper trial version now. I don't even know what the bloody thing is named! Any thoughts?
What's the little bugger doing, browser hijacking? Does it show up in the task or processes list? There's a link on this thread to a page that has every Windows process known. You can narrow it down from there, and find information on removing the pest.
That's what I'd do, anyway.
I can run HJT in Safe Mode and do the fixes on the entries (it adds a LOT of host file entries that redirect to porno sites) but when I boot in normal mode they all come back.
CWShredder says it CWS.Smartsearch.2 and it remove an items called CSW.GoogleMS and about:blank each time but it just comes back.
Nothing I've seen yet shows up in any running processes. It's not a fatal type of bug but it is uber-annoying.
I'll look through the list of Win procs at the link you suggested and see what I can find. Nasssty little spywareses. We hates them.
