I have noticed that in My Documents I have a folder called My Chat Logs. Inside this there are folders named after the current months. All of the chat logs are in Notepad format. Some of the chat logs can just be opened, but I have recently noticed that some of them have an extra icon beside them and they are now encrypted. If I try to open these it asks for a password. I have no idea what the password would be as my partner and I have not set one up. No one else could have set it up either as it is a private laptop. Any suggestions? The chat logs are all ones from MSN Messenger.
