It looks like a virus to me. I have certain number of video files stored in my hard drive. I want to get rid of them, but when I delete it, I receive a error that cannot delete the file access denied. I have around 4 accounts in the system. I am a bit confused to find which one is limited. So I checked in Control Panel > User Account. In that I can see my account is Admin. So I have the full rights to delete files. But why I am not able to do the same. I had downloaded this video through a software on my system. I am using Windows Vista Ultimate. I tried to check the File Properties where ample of time it is marked as Read Only or locked. But those things were not available. What should I do to delete the files. I hope this issue only lies with the video files that I have, now with others. Thanks.
