Possible virus, unknown .DLL at startup

Longtime lurker, just signed up recently, but have browsed these forums to fix various issues in the past.
Recently built a new system, only been running it a few days, been tweaking it , removing unwanted startups, etc. Upon running MSconfig i see a randomly named Rundll32.exe that i have no clue where it came from. I've disabled it and it reappears on my startup menu, deleting the dll just invites a newly randomly named dll to take its place. Here is a hijack this log taken about 5 minutes ago. Any help is appreciated.
