Rundll keeps reporting missing Anaccess.dll

Hi, Been having this problem a while now on start-up keep getting rundll reporting it cannot find:

C:\Users\xxx\AppData\Local\AnciStea813\Anaccess.dll

Checked hard-drive and there is a folder there with Anaccess.dll in it and that's all - not sure why its even there. I have checked registry and cannot find any instances of either the program folder or dll and nothing in task manager appears to be associated with it. Also checked all installs for that day and cannot find anything that helps me identify why and what its trying to run.
Any help in removing the Rundll pop-up would be gratefully appreciated
Many thanks

Any ideas anyone?

Hi all,
Well I finally solved this using Autoruns.

Just found the instances that were requesting the missing dll file and deleted them
