bjerde.dll is that a virus?, Info about strange DLL

Viruses and worms
1

I think I found a virus on my PC:

Windows Vista Business
32 bit
Service Pack 2

I tried running various scan with Kaspersky, Avast, TrenMicro HouseCall and other anti-virus programs, but none of them report
any infection.
The problem seems related to a file:

bjerde.dll

located in:

C:\Users<user>\AppData\Local

which reports itself as:

Cyberlink PowerDVD software

a software which I never installed on my PC.
If I remove the file after some short time ir reappears, probably because I found in the registry (HKCU:Run)
the value:

rundll32.exe “C:\Users<user>\AppData\Local\bjerde.dll”,Startup

which has the value:

Ytecupiyepeteroq

as program name.
A search on the web for the dll name or the program name produces no results.
The DLL seems also to create exe files in:

C:\Users<user>\AppData\Local\Temp

which periodically ask for user account verification to be ran (sorry but I deleted those file without recording the names).
I was able to reboot the PC in Linux and remove the file (bjerde.dll) so that is not executed anymore,
but I do not really know if my PC is safe any more!

Has anybody any information on that DLL?

Thank you very much.

Download Malware bytes and run a scan with there program. Post log when complete.

Also with running a scan with numerous different anti virus software were you sure to uninstall the previous one prior to attempting a different anti virus program?
EDIT: Forgive me for those are online scanners.
