What software did you download?
Where did you download it from?
Do you access internet through a wireless router or are you wired?
What anti-virus do you have?
(CPU is only a small part of a PC)

then you will need 3 logs which is detailed in the link. remember to post those 3 as the specialists will need it to help you. but if you can do one thing for me, open task manager: ctrl + alt + del and under "Processes" do you see Rundll32.exe ? if you do, msg me because i've been trying to study these viruses for a while

Just so you know...as long as a user is running Windows, rundll32.exe is expected to be a running process.

sorry, i meant if there are multiple

It's also fairly common to have multiple instances.  I currently have two running: one being used by my nVIDIA graphics card, and one being used by my Creative webcam.  The trick is to use a program such as Process Explorer to see where the file is and what is using it.
