I use Windows 7. I have 8 gig of RAM. Something eats that memory rapidly whenever I open my video folder. I have run anti-virus scan and Spybot S&D, which didn't find anything, but I think I have determined what it is. I discovered that a Youtube video there is a problem. It will not delete or allow any change to be made, such as relocating or renaming. No other file presents that problem. When I open the video folder, the folder goes into a state of continuous loading. When I try to delete that video, the video goes into a state of continuous loading to the recycle bin without ever deleting. Meanwhile, my RAM drops very rapidly so that if I use the computer for only a few minutes, it is so low that I have trouble even shutting down. Closing the vieo folder doen't help, the loading continues. The video is at - don't download it ! I used Firefox Download Helper, got the Medium MP4 version of the video. The thing is only 13.7 mb. What is wrong with it and how do I get rid of it?
