Step-by-Step Solutions

  • Sort by Recently installed.
  • Uninstall programs you do not recognize or did not intentionally install.

6. Reset Browser Settings

  • Ensure real‑time protection is enabled.

8. Restore From a Clean Backup (If Needed)

  • If the system remains unstable, restore from a backup created before the infection.
