PowerReg Scheduler V3.exe and msmsgs.exe question

Hello people,
The other day I did a virus scan with avg and it found a trojan on my pc. It fixed it but I still did another full system scan with spybot, adaware and Avg in safe mode with system restore switched off just to be on the safe side. All results came back negative and I also ran CClean. However today I thought I'd do a HijackThis scan. It listed a couple of things I wasn't to sure about one of which being PowerReg Scheduler V3.exe and msmsgs.exe. I did a google search on both of them and one website said that V3.exe was adware but I couldnt find out for sure if msmsgs.exe was genuine or not. As i'm not too sure how Hijackthis works I was hoping one of you friendly people could take a look at my logfile and tell me if everything is ok?. Just let me know if you can and i'll attach the file. Any help will be much appreciated!

 

I followed the steps in the link you gave me and I think everything related to powerreg has now been deleted.

msmsgs.exe is located in C:\Program Files\Messenger\msmsgs.exe on my pc. Is this good or bad?.

Thanks for your help.
