Molebox Launcher fatal error

I recently purchased a Vaio CR410E with Vista pre-installed, and decided to
rely on my school's anti-virus software (Sophos) as my primary anti-virus
program since I have used it before and is vista compatible.

After I uninstalled Norton, I began to get a pop-up in the beginning when i
start windows that says:

Molebox Launcher fatal error!
..DLL corrupt

i've tried everything, from my Sophos anti-virus scanner, to Spybot, to
cleaning up my registry with CCleaner to System Restore, but nothing! Other
forums have proved largely unhelpful, or at least i'm not turning up the
right pages in my search. Does anyone have any advice? It disappeared for a
little bit at some point, but when icame home tonight and turned my laptop
on, the same message popped up.

Hello Mingular,

Go to http://onecare.live.com/site/en-us/default.htm and do a scan

This is Microsoft's free public anti-malware scanning service.

If you have any trouble with this--it can also work from safe mode with
networking--so restarting in that mode may help especially with cleaning.

I hope this post is helpful, let us know how it works ºut.

I use the programs below for Security.
Also, to remove probs is there as well.
