FAQ
Is free antivirus enough in 2026?
For many users, yes—especially with safe browsing habits and regular updates. The latest independent lab evidence shows several free engines at top protection levels. If you need extras (VPN, password manager, identity monitoring, parental controls), consider a paid suite.
Can I run two antiviruses together?
Avoid running two real‑time antiviruses simultaneously. Use one real‑time AV and keep Malwarebytes Free as a second‑opinion cleaner.
What about Mac and mobile?
Bitdefender, Avast/AVG, and Avira offer Mac and mobile apps. iOS relies more on sandboxing and App Store checks; still, browser + phishing protections help.
