Antivirus Software for PC Free Download: Backup First

Antivirus software helps detect and block malware on a Windows PC. But if files are already deleted, encrypted, or corrupted, antivirus alone may not restore them. Backups are still necessary.

Use Windows Security First

Windows includes Microsoft Defender Antivirus, firewall, reputation protection, and controlled folder access. Keep Windows Security and updates enabled before testing third-party antivirus tools.

Run a Basic Windows Security Check

1. Open Windows Security from the Start menu.
2. Choose Virus & threat protection and update protection definitions if updates are available.
3. Run a Quick scan first. If the PC still behaves abnormally, run a Full scan or Microsoft Defender Offline scan.
4. Review detected items before removal. Quarantine is safer than deleting unknown files immediately.
5. If files are encrypted, missing, or damaged, do not assume antivirus can recover them. Use backups or recovery tools.

Pick Antivirus Software Carefully

Download antivirus tools only from the vendor's official website or Microsoft Store. Avoid cracked installers, bundled downloaders, and pop-up warnings from unknown websites, because they may add the same malware you are trying to remove.

Back Up Before Virus Removal

• Free Download

Step 1. Open Qiling Backup and choose File Backup for important files or System Backup for Windows rollback.

Step 2. Select user folders, project files, browser profiles, or the full system according to the risk level.

Step 3. Save the backup to an external drive and click Proceed. Disconnect the backup drive after the task finishes to reduce malware exposure.

Conclusion

Use antivirus to prevent and remove threats, but keep a separate backup for recovery. The two tools solve different parts of PC protection.
