Two folder trees (that I'm aware of) appear to be empty. Naturally they're the core shares for the system. When looking at them in Windows Explorer the root folder shows without the + sign indicating the presence of sub-folders, and clicking on that folder nothing appears in the right pane.
A right click on the folders shows that data are there, but it's simply not visible.
After running an AVG scan 61 occurrences of 2 things were found and removed: Worm/Autorun.inf, Trojan Horse Dropper.Generic7.CMLQ
Update - it looks like all folders have been set to Read Only and the ones I asked about originally have also had their System attribute turned on. If I turn off hide protected OS files I can see the folders and their contents but can't change any attributes
OS is Windows Server 2008 R2 Standard SP1
Any help please?
