If you have lost use of your computer after using Driver Updater with Windows7 here is a likely fix.
Here is what we finally found to fix the issue. Found on wikiHow. If your computer is operating satisfactorily there is little reason IMO to update old drivers especially if the updates are also old.

Problem: Avast Driver Update may have corrupted my pc device drivers. Completely locked out of my computer
Sign-In screen with no cd/dvd drive, usb drive, mouse, or keyboard functions except for the Esc key,
Enter key and the 4 Arrow keys.
Fix: Repeatedly tap or hold down the F8 Key simultaneously when you press the computer “Start” button.
This will take you to the “Safe Mode” screen. Above the 3 Safe Mode options you will see the
words “Repair Your Computer”. Use the “Arrow Key” to highlight the “Repair Your Computer” option,
then press the “Enter Key”. This takes you to “System Recovery” to select your country and select the
name of your computer, i.e., hp elite 8200, then click “Next”. This will bring up the "Start Repair/System
Recovery/Command" options. First, I used “Start Repair” and discovered that Avast Driver Update had
corrupted 11 drivers, so I did a System Recovery using the last recovery date before the Avast Driver
Update quickly restoring all functions and files. The above Wiki website explains these steps by showing
the windows with helpful step explanations. It brought my Windows 7 Professional computer back to life.
The Avast technicians tried to help but their several suggestions did not work. The tech’s last email
advised “I have a hardware problem!” Well, no longer… I fixed it myself with Wikihow and some prior
experience using System Recovery! Good Luck.
