When skimming through the info, I found the following ones suspicious, and found some quick links:
http://spywarefiles.prevx.com/RRFAHI.../UZCX.EXE.html
http://www.neuber.com/taskmanager/process/acs.exe.html


Personally, I'd format the whole thing and make a clean install. Then make sure any type of rubbish doesn't come at it, just prevent all these things.
