I have some more than 100 exe files in a folder. I have enough RAM(4GB). Every other tasks in my system works just fine when I open this particular folder the the explorer doesn't respond. I scanned the folder and my system for virus. I don't have virus [as per result by McAfee, Kaspersky and Windows defender]. I have no clue what may be possible cause for this?

probable guess would be bad sectors –  Sathya Dec 11 '12 at 6:37
@Sathya: Just got a new hard drive. 2 days ago only. –  NewUser Dec 11 '12 at 6:38
doesn't mean new hard drives can't contain bad sectors –  Sathya Dec 11 '12 at 6:40
how to check for bad sectors? –  NewUser Dec 11 '12 at 6:41
Do you have McAfee, Kaspersky and Windows Defender all running at the same time? Maybe that is what is causing the slowness. It's generally considered not to be a good idea to be running more than one virus checker at the same time. –  dangph Dec 11 '12 at 8:07
