When deleting data on a computer, the data is only deleted logically and not physically for the time being. This means hackers can restore partially or completely deleted data on a hacked computer.
To avoid sensitive deleted data being recovered, use Avira File shredder to permanently remove the data.
- Open the Avira user interface and click Privacy → File shredder → Next.
- Select the data you want to delete and click Shred.
- Confirm shredding with Yes.
- Close the result list with OK.
