If you really have all that lot open, of course your PC is going to run slowly!
C: Program Files\QBU\QkOnBtn.EXE - do you know what this is?
C: program files\zango\zango.exe
apdproxy.exe
BearShare.exe
All these 3 are nasty, or potentially nasty.
Get Spybot, Adaware and ewido - all free anti-malware - and run them.
Then start cleaning out all the crap! Most of the stuff that autoloads is not necessary.
BTW, the scan is dated 19 Jan - either your PC is running VERY slowly or it's taken you more than 4 months to decide to do something about all this.
