Avira

Avira is a long-established German security company whose software protects computers and phones against viruses, malware, phishing and dangerous websites. It's best known for one of the most complete free tiers on the market — real-time antivirus at no cost — which is how most people first meet it. The paid plans build upwards from there: Avira Prime adds an unlimited VPN, system optimisation tools and priority support across five devices. Think of it as the free-first brand of this comparison: an excellent no-cost entry point, with the paid tier as the optional upgrade rather than the starting requirement.

Very safe — Avira scores well in independent detection tests and reliably blocks malware, phishing and dangerous websites, and the free version runs the same core protection engine as the paid plans. The gaps are commercial rather than protective: the free tier prompts you to upgrade and caps its extras, but the protection itself is sound. It remains one of the most reliable free options on the market.

As a free antivirus, one of the best available: complete real-time protection at no cost with genuinely good detection — the reason it earns a place in this ranking at all. Its limitations are commercial rather than protective: the free version regularly prompts you to upgrade to Pro, the free VPN is capped at 500 MB per month, and it leans on your system slightly more than ESET or Bitdefender do. If you want free protection with a clear upgrade path when your needs grow, Avira is the strongest candidate in this field.

All the mainstream categories: viruses, trojans, worms, ransomware, spyware and adware, with phishing sites blocked before they load. Its engine scans files and downloads in real time rather than only on demand, so threats are caught on arrival — and the same detection engine works in both the free and paid versions.

Three honest ones. The free version markets at you — persistent prompts to upgrade to Pro are the price of 'free'. The free VPN is capped at 500 MB per month, enough for occasional banking on public Wi-Fi and little else. And it has slightly more performance impact than the very lightest rivals, ESET and Bitdefender. On the paid side, Avira Prime starts at US$59.99/yr for the first year and renews at US$104.99/yr — a rise worth diarising, though a 60-day money-back guarantee softens the commitment.

Yes — Avira Free Security is a genuinely free, full plan: real-time antivirus with no expiry date, not a trial. The paid tiers reserve the advanced extras — an unlimited VPN, the full optimisation toolkit and priority support — topping out with Avira Prime at US$59.99/yr for the first year across five devices, backed by a 60-day money-back guarantee. If you only need core protection, the free plan is the honest recommendation; upgrade when the capped VPN and the upgrade prompts start to chafe.

Yes — Avira is a long-established German company with decades in security software and a solid reputation, and its products earn strong results from independent testing labs. Its free tier is among the most widely recommended anywhere — the kind of standing a brand only sustains by staying trustworthy over many years. A dependable European option in this field.
