im just trying to find out what is spyware and stuff. i read that rundll32.exe can be really harmful if its not what you think it is. and i have three copies of this exe running right now? someone wanna fill me in here and how to check if its spyware or not?

if you would like to check you whole cpu I suggest these two FREE anit-spyware, and anti-virus software programs:

Spybot – http://www.safer-networking.org/en/mirrors/index.html

AVG Free – http://free.grisoft.com/ww.download?prd=afe

Just boot in safe mode and run those two scans
