Avast Driver Updater Screen flashing

Got a message to update 6 drivers and did so.

After updating, got another message that said had 5 more.

Clicked to update and screen started flashing.

Had to shutdown computer as it kept giving messages

that it was updating 39 drivers. Restarted computer and

went to uninstall, Asked to Repair or uninstall.

Picked repair. Said it repaired but screen still flashes when trying to update.

Picked uninstall and uninstalled program but didn’t check the box to remove files and logs that wouldn’t allow

you to restore a driver. Reinstalled program, but it didn’t solve the flashing issue.

Wanted input as to checking the box to uninstall everything. Can anyone answer that question as that is what I am

thinking to do next.
