Although your device may not strictly require an antivirus app, having one can significantly enhance your overall security posture.
How can I recover my data after a virus removal?
Recovering data after a virus removal largely depends on whether you performed a factory reset and what kind of backup you had in place. If you created backups using Samsung Cloud or Google Drive before the infection occurred, you can easily restore your data once the virus has been removed. Simply navigate to the backup settings within your Samsung account and follow the instructions to restore your files and settings.
If you did not back up your data prior to the virus infection and your files were deleted during the removal process, recovery can be more challenging. You might consider using third-party data recovery software, although success rates vary. Always remember to consider regular backups of your important files in the future to prevent data loss from similar incidents.
