.dll file source?

Is there a simple way to establish what program a corrupted .dll file is used for? Examining this file (EONSYSREV_1.DLL) with a text editor didn't help, and a search for this file came up with nothing.

 

It might be a baddie. Have a look here

I'd run an online scan at Trend Micro HouseCall or Panda Active Scan

Also please do this:

Go to http://www.spywareinfo.com/downloads.php#startup , and download 'Startuplist'.

Unzip, doubleclick it, and it will generate a text file that will list all running processes, all applications that are loaded automatically when you start Windows, and more.

Go to Edit > select all, copy it and please post the contents here.

 

Tony,
I'm running online virus check now. Ad-aware & Spybot do not highlight this file as spyware.

These are the results of startuplist:

And...Trend Micro virus check came up all clear. Anyway, if this .dll file relates to a buggy program I've recently installed, I suppose I'll find out eventually.
