Antivirus Software
Antivirus software detects and responds to malicious files and activity. Choose a product by the devices you need to protect, the controls you want to manage and the features included in the exact edition.
What to compare
- Device coverage: confirm which platforms and how many devices the license covers.
- Protection features: distinguish file scanning from web filtering, firewall controls and other extras.
- Administration: compare notifications, scheduled scans and management across multiple devices.
- Evidence: assess protection and performance using dated, reproducible tests for the relevant edition.
Check your existing protection
Windows Security includes Microsoft Defender Antivirus and Windows Firewall. Adding a third-party product is a feature and management choice; built-in protection should not be dismissed without evidence. Check the active protection status before changing applications.

Keep protection and recovery separate
Security software does not replace a backup. Maintain recoverable copies of important files, keep applications updated and review alerts. A wider feature list does not establish better detection quality.
Some catalog entries describe older product names. Confirm the vendor documentation for the edition you intend to use rather than assuming that a familiar family name guarantees current availability.
