I have already searched it on net but nothing was satisfactory. Actually, I am not able to run Adobe Pagemaker program until I go to Task Manager and end the Rundll32.exe process. After ending this process only I am able to run Pagemaker and my system also gets fast after killing this process. I have tried Ad-aware also, it diangnoses some critical processes running in my computer but I find them after restring my system even though I would have cleaned them through Ad-aware. Please help me. Ravi

Ok, I'll make sure to stay away from attempting to help you in the future.
Have a good day.

OK if you don't like Need's advice and you have tried EVERYTHING mentioned on the link, then your best course of action would be a complete CLEAN reinstall. TOTAL format of the hard drive and rebuild your OS.
