Hard Drives have disappeared from Disk Management

My hard drives have disappeared from Disk Management. Not sure when.
Only the DVD drive remains in the list.

Drives are still visible in Windows Explorer.
Drives work normally.

Windows Explorer >> http://i494.photobucket.com/albums/rr303/lyleisaacs/Explorer.jpg

Computer is set up as dual-boot Windows 7 32bit and Windows 7 64bit on
separate partitions.
Only the 32bit version has this problem.
I signed in as another user (Admin) and result was the same.


A TDSS rootkit virus appears to be the culprit.
Computer started hijacking Google page and sending me elsewhere.
Kaspersky firewall detected the internet traffic.
None of the antivirus programs (AVG, Avast, Kaspersky, McAfee) detected the infection.
Rootkit removal tools failed and left me with an invalid (no key) copy of windows.
Fresh install of Windows 7 fixed my problem.
