How can I undo changes which AVG PC TuneUp has made to my PC?

In rare cases, AVG PC TuneUp updates may cause issues with certain applications on your PC, stop certain files from opening, or slow down your PC. Undo changes by following the steps below:

  1. Click the AVG PC TuneUp icon on your Windows desktop to open the user interface.
  2. Click the Rescue Center icon in the bottom-right corner.
  3. Select the action you want to undo and click Restore.
  4. Click OK to confirm.

Note: the date when the change was implemented is shown to the right of each action. If you are unsure which change caused the issue, we recommend undoing changes which were implemented most recently, or just prior to when you first noticed the issue.

What can I do if a disk check stops mid-progress?

When you Check hard disk for errors and select Thorough analysis, your computer restarts and the disk check runs during startup. In rare cases, the disk check stops mid-progress and may appear unresponsive, typically at around 27%. If this happens, we recommend following the steps below:

  1. Allow up to 2 hours for the disk check to complete.
  2. If the disk check remains unresponsive after this time, restart your PC.
  3. During reboot, you see a prompt to skip the disk check. This prompt appears for 1 second only, so we recommend pressing the SPACE key repeatedly during reboot to skip analysis.
  4. Download the CheckDisk mod tool. This ensures that AVG PC TuneUp does not attempt to continue the disk check next time you start up your PC.
  5. Run the downloaded tool, then click Continue.
  6. The Work done dialog appears.

Disk check during startup is now disabled
