for some time now files and downloads on my pc have been getting corrupted. It has been selective. The files are still there but they are unusable. I can not copy and paste or print anything. Folders now contain allot of garbage including files I cannot open or if I can they are blank. Folders have been filled with garbage eating up disk space and requiring much time to clean up. I am running Windows 7 ultimate and have Kapersky total protection. I do my best to keep everything updated. I know nothing about script and programming. I tend to learn what I need to as I need to. I have tried the netstat command to identify what is accessing my pc but can only find legitimate programs. I don't think this helps anyway.
