Possible Infection: Four Instances of rundll32.exe, Nothing Detected by MBAM Pro?

[Valor]

I have two instances of rundll32.exe on my computer, I am aware that rundll32.exe is an essential Windows component, but the location is not.

One of the rundll32.exe's is in C:\Windows\SysWOW64

Another is in C:\Windows\System32

Another is in C:\Windows\WinSxS\x86_microsoft-windows-rundll32_31bf3856ad364e35_6.3.9600.16384_none_6ca51616c6842822

The last one is in C:\Windows\WinSxS\amd64_microsoft-windows-rundll32_31bf3856ad364e35_6.3.9600.16384_none_c8c3b19a7ee19958

 

Keep in mind I am running Windows 8.1, I am very scared this is a possible infection. I checked my Task Manager the other day and saw two instances of rundll32.exe, both running NVidia software, so I figured it was not a problem until I opened the file location. I have been taught that rundll32.exe is only under System32, I could be wrong. I've scanned with many programs(Avira, Malwarebytes, MBAR, McAfee Anti-Rootkit) and no detections, please respond quickly so my mind can be at peace, cheers!

I meant four instances in the post, sorry.

These are locations for the - let's say - backup copies of legitimate system files.

 

Please stick within one topic. I'm closing this one.
