I currently using a Sony laptop with window vista home premium. Few days ago, my laptop started to have some malware called Antimalware doctor and Your protection so, i tried spyware doctor to remove it but it didn't seem to work so i had to remove it in regedit area. Luciky, the malware removed but my whole system is down. I can hardly start my laptop in a normal mode as I can't get into the login screen. But, even after the winsow started up, none of the program were able to open up after about 10 mins and the program openned were soon not responding , including the task manager. So is there anyone know what's the problem is and how can i fix this?
