Rundll 32
I have been wanting to contact a few organisations, but whenever I try to send my message I get a window opening wanting me to run" Windows host process (Rundll32)". I gaggled it, but I couldn't make head nor tail of it. Can anyone give me a simpletons guide to what it does. I particularly want to avoid giving anyone access to my computer for advertising/spam by running this programme. Is this safe to use?
