In a hush-hush operation last night I installed a USB sniffer that seems to have deleted or deactivated the usb drivers on my Windows 7 box. Even after a restart not a single usb slot works. So obviously all my usb drivers are broken.
What can I do now? Don't have a manually created restore point. Does Windows 7 DVD System Restore help?
Or are there some tools with which I could restore drivers or important system files?
