    How to tell if Windows host process (Rundll32) is malware or not?

    Greetings,

    I am in need of some assistance about the Windows host process (Rundll32). Just today as I was looking through my icons in my taskbar on my standard account, I noticed that there was a process labeled “Windows host process (Rundll32)” and I don’t remember ever seeing it before (if not maybe once). But after doing some research, I did the following:

    1.) I did a search in my Disk Drive and noticed that the only Rundll32 files on my computer were the ones that are with my amd processor, the default windows location files, and Malwarebytes Pro.

    2.) I have done numerous full, quick, and flash scans with Malwarebytes Pro and Microsoft Security Essentials but nothing is detected.

    3.) I have tried going into safemode, but it still appears in the list,

    4. I logged on into the Administrator account, and noticed that the process labeled “Windows host process (Rundll32)” is not on the list anywhere (I only use the Administrator account for installing programs only, nothing else. I use a standard account for everything else).

    5.) After reading some research, I noticed that it could be some of the programs I have installed on my computer that maybe using it. However; I can not determine which ones it could be. Here is the list of the programs I have installed and what the taskbar looks like.

    6.) I viewed my running processes in task manger and it does not appear.

    Although the icon has not appeared at all or gives me notifications, it still worries me. So is this a virus that’s harmful to my computer? Please let me know.

    Thank you so much for your assistance. 🙂
