You might have to remove hidden file attributes to find it. But if it does, try renaming and moving it next time that malware is removed. If your machine still works fine, delete it, and purge the Recycle Bin. You will probably have to take ownership of the file to do this. You will find instructions about how to do that in the Windows help file.

But this file is why the beastie keeps coming back:

BrowseMark.Bromon.dll

That's a dynamic link library. They have information stored in them for programs to retrieve. There's another file yet involved that runs at startup that needs gone as well.
