Hi,
Covered - here are some pointers:
http://www.symantec.com/security_response/writeup.jsp?docid=2007-042306-2226-99&tabid=3
Navigate to and delete the following registry entries:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies
\Explorer\Run\"WinFile" = "%System%\drivers\Invalid.exe"
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies
\Explorer\Run\"DataAccess" = "%Windir%\Invalid.exe"
(The above two entries were not found in my registry but by resetting
the values of the following two, my "Drive letters" became operable
again.
"Recycler.exe" is a bug, it would seem, & can be "carried by anything
moved by a data pen".)
Restore the following registry entries to their previous values, if
required:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies
\Explorer\"NoDriveTypeAutoRun" = "95"
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer
\Advanced\Folder\Hidden\SHOWALL\"CheckedValue" = "0"
Exit the Registry Editor.
