Free antivirus and malware-removal tools: official download checklist

Basic check order

1. Start from the antivirus vendor domain or official store path rather than an infection warning popup, coupon page, or generic cleanup portal.
2. Decide whether you need a one-time malware-removal scanner, real-time antivirus, browser protection, or managed endpoint security.
3. Check whether Windows Security or a company-managed endpoint tool is already active before installing another real-time scanner.
4. Review free-versus-paid feature boundaries, renewal prompts, support channels, business-use terms, and uninstall options before rollout.
5. Document the official download page, installer publisher, review date, alert owner, and device offboarding plan.

Cautions and operating tips

• Two real-time antivirus tools can conflict, slow devices, or create confusing quarantine results; pair a primary protection tool with occasional scanners only when policy allows it.
• Scareware often uses urgent infection wording, fake support numbers, or remote-access pressure even when it imitates a real security brand.
• For work devices, the best answer may be to keep the managed endpoint tool and use approved cleanup or escalation procedures instead of adding a personal-free antivirus.
