Help! "wmsetup.dll" MALWARE

[new_man]

I found this strange dll file inside the %temp% directory. result of Google told me that file is malware. So I know that file is dangerous. But I can't remove it. Here is what happened when that malware in actions :
10 mins after computer boot up, there's nothing happen. Everything seem to be normal. But after 10 mins, my network activity is dramatically increased. In fact, I did'nt do anything, even I'm not browsing. Then I trace that,and found my %temp% dir is filled with file '01.gif', '03.gif', and 'xx.gif' (note that 'xx' value is random number). I see on my task manager that there are more than one 'rundll32.exe' proccess are running (two or three and sometimes four process run at the same time). Then I trace that and found these another dll files : c:\windows\apppatch\desktopwin.dll, c:\windows\update.dll, and c:\windows\sysocmgr.dll. I don't know if there are another malicious dll files. Even after that, there are another strange process are running, they are c:\windows\system32\explore.exe, and c:\windows\system32\lenschk.exe. Oh yeah, i forgot, there is iexplorer.exe process, but I didn't open any web browser. And time after time, the computer is getting slow and slower. And finally, it crash, freezing, there's nothing else I can do.
