Hi Guys, I need help. I'd just been organising/editing my music and tags (folder location, disc number, track name) etc, and now have strange behaviour. I was moving some mp3s from one big folder into 3 separate sub-folders (Disc 1, 2 and 3). When it got to the 3rd set, I couldn't paste, and have now realised that most of the folders on my computer show as "read only"! Everytime I try and change untick the box/option, it goes straight back!! Arghh. My NOD32 updates expired a couple of days ago, but the Antivirus was still running. I've been meaning to renew it, but I should point out that I hadn't been downloading anything at the time, so didn't have any incoming traffic as far as I was aware. Other abnormalities include being able to edit names of SOME of these sub-folders, but not all. I now cannot edit the name of the "Disc 1" folder, but can with the folder, "Disc 3", which was the most recently created. What's even more strange is the "Disc 3" folder shows as "read-only" and I can also edit the names of the files in the "Disc 1" folder. In case a recent Microsoft Update this evening was the unlikely cause, I did a System Restore. I still have the flaming problem. NOD32 has given me no alerts. Thanks for any help.
