When deleting data on a computer, the data is initially only deleted nominally but not physically. This means hackers can restore partially or completely deleted data on a hacked computer.
To avoid sensitive data being recovered, use Avira's File shredder feature to permanently delete the data.
1. Open the Avira user interface and click Privacy → File shredder → Next.
2. Select or drag and drop files you want to delete, and click Shred.
3. Confirm shredding with Yes.
4. Close the result list with OK.
