  if u r using norton antivirus then it really slows down the processing speed as there are multiple options apart from scanning the drives.u can give a try to Zone Alarm.It will basically help u concerning the security while using the internet.

  Hi Shikhar,
  
  An A/v will typically scan your machine and files for infections and virus. So it translates into a lot of disk i/os. If you check out that metric in your task manager you will understand what I am talking about.

  Parneet, I understand and appreciate your interest for the Virus / Anti Virus threads (I have noticed that all your posts goes to Virus / Antivirus thread.). However, there is no use of digging such an old thread. So in place of digging down old threads, you can start a new thread with explanations of your views about that problem.
  
  No offence means, please.
