Hi all,

I have Vista Ultimate.

In my E drive, all the folder names are vanished.
I can see the names on the Details Pane, but not on explorer.

I can see the names of all the subfolders though.
here's the screenshot:

this seems to be the work of some malware. Update your AV and go for a through scan

I have the latest version of avast, fully updated.
I ran a full system scan, but no virus was found.
