I'm running Windows 7 Ultimate 64-bit.
I found a file in c:/Users/name/AppData/Local called shanjou.dll
I noticed it when I ran msconfig and had a look through why my startup was taking a long time and this is where I noticed an entry for RunDll32 being executed against shanjou.dll
I ran a few searches on the name but nothing came up. MS Security Essentials doesn't detect anything wrong with it. What should I do next? I have already moved it out of it's location into my own self-made quarantine folder.
