Few days ago my pc was seriously affected

Few days ago my pc was seriously affected with malware and i thought my computer was dying, taking it's last breath. So i was downloading trial version anti-virus to see which one was the best. There at that time i came across Doctoantivirus. After using 7 antivirus i installed the trial version of Doctoantivirus. After scanning the computer i was astonished to see the outcome. It was like my computer was reborn, now it work as fast as lightning. http://www.slideshare.net/JoanWilliam/doctoantivirus-a-musthave-protection-for-computers
