I am running Windows 7 on a recently bought HP PC (AIO-200-Quad). I only have one user name defined on this PC. I have one printer installed, plus Windows Live Mail, IE8, and Office 2010 H&S, and Norton Internet Security 2011.
The appdata/local folder for that user keeps getting new hex folder names (Long names containing Hex digits and dashes, surrounded by curly braces) created in it. From 1 to 3 folders are created each day since the day after this PC was first powered up. All of these folders are empty. I haven't been able to directly correlate it to any specific activity that I'm doing yet, although there is some evidence that Norton scanning for spam e-mails is one of the culprits.
What application(s) or OS function(s) are creating these folders? Can something be set so they are deleted when they are no longer needed? (Disk Cleanup does not delete them) Are they safe to delete directly via Windows Explorer?
