Hmm, might be a virus trying to act like it's not. I would suggestion going to this computer tech site

http://www.cybertechhelp.com/forums/

Go into the cycber safety forum, run the highjack log (it is not threat. I used it myself, all it is, is a log of what is running on the program, anyone that has the knowledge to read it will be able to tell you whether or not, it's a virus)

I found out that windows messenger uses a lot of cpu, and tons of memory as well. Since I never use it, I uninstalled it. Just go to add and remove programs,add and remove windows components(on the left), scroll down to Windows messenger, uncheck the box, click next. See if that helps.
