I tried safe mode and am able to create folders there but not in normal mode. I scanned my pc using Norton antivirus and also tried sfc/scannow.Yet i am unable to create folders in normal mode in the desktop.When I try to create folders elsewhere (in other drives) I am able to do so. It is only in the desktop that I am unable to create folders. And if you say it is a virus then what precautions should I take and what should I do further to rectify the problem? I am using a licensed Norton 360 software that has worked wonderfully so far and has protected my pc from virus and malware for the past 3 years. This is the first time I am getting a problem.
