I have To Clearn My PC Virus

Did I tell you that my computer in the office looks terrible now? Hmm...It not the computer looks terrible but is the system itself looks terrible now. I think I am download too much of music from the internet and has brought some virus or Trojan into my computer. I am very worry now, because I scare those virus will damage my company data. I am thinking to subscribe to the NOD32 antivirus software now. One of my blogger friends introduced this software to me; he said this would be good software that can help me to clear all the virus, worm, spyware, and Trojan. I hope it works well and help me to get those things out of my pc.
