Shut Down troubles..

this may seem a little vague, but whenever i try to shut down my pc i get a popup telling me that *something* is shutting down, it doesn't have a name, just says that it's shutting down...or it's frozen. i end up having to reset the machine to get it to shut down. i'm also having trouble getting some programs to work (VEO-for my cam and WinAmp just to name two.) i've run SpyBot, but the only thing it found was something called "Purity Scan"...

here's my HJT log...i'm just curious if there's anything funky on it. thanks in advance for Your help
