Antivirus by key: ESET NOD32, Avast, Dr.Web and Malwarebytes — one year or perpetual
On a digital-goods marketplace an antivirus is a regular activation key: you pay, get a code and enter it in the program’s settings; the installer comes from the developer’s official site. The catalog lists several such offers — one-year ESET NOD32, Avast Premium Security and Dr.Web Security Space keys and several Malwarebytes options — let’s see how they differ.
ESET NOD32: internet security for a year
ESET NOD32 Internet Security (newer releases ship as ESET Home Security Essential) is a classic internet-security suite with real-time protection against viruses, trojans and spyware. The ESET NOD32 Internet Security — 1-year key (1 PC) listing covers one computer for one year. Key terms from the seller: the key is entered inside the app only (not via the ESET website or portal), must be activated within 48 hours, and the term can be 1–20 days short of a year — the promo key cannot be linked to a personal ESET Home account. Windows XP, 7, 8 and 8.1 are not supported.
Avast Premium Security: internet security for a year
Avast Premium Security is another classic internet-security suite by key: virus and ransomware shields, blocking of fake and phishing websites, and tools for safer online shopping. The Avast Premium Security — 1-year key (1 device) listing is a licensed key for one year and one device; unlike ESET, delivery is instant — the key is shown in your browser right after payment and copied to your e-mail. Download the Avast app from the developer’s website and enter the purchased key during activation. The seller does not specify regional activation terms — ask before buying if that matters to you.
Dr.Web Security Space: a Russian antivirus for a year via a key file
Dr.Web Security Space is an all-round antivirus from a Russian developer for Windows: protection from viruses, ransomware and network threats, a firewall, parental controls and link checking. The Dr.Web Security Space 12 — license key listing is version 12.5, valid until 12 February 2026. The activation format differs from ESET and Avast: you receive not a key string but a key file (.key) via a direct link right after payment, plus installation instructions. The license type is Shareware: the keys are public and activate via the key file. There are no regional restrictions and no extra activators are required; the platform is Windows only.
Malwarebytes: anti-malware in three formats
Malwarebytes is a specialised anti-malware tool: it blocks malicious software, ransomware and malicious sites, cleans up an infected computer, and often works alongside a primary antivirus. The catalog has two listings:
- Malwarebytes Standard — subscription or perpetual key — dated subscription keys (up to January 2027) and a perpetual LifeTime option, activated in the app’s license settings without signing in. Dated plans also cover macOS and Android; LifeTime is Windows-only and activates in app version 4.6.17, with the latest version installable on top.
- Malwarebytes Premium — perpetual licence for 1 PC — a License ID and a key for the official version 4.6.x on one Windows PC; no account binding, no regional restrictions on activation. The key is incompatible with version 5 — the 4.x client is installed from the seller’s link.
- Malwarebytes Premium — lifetime activation key — another perpetual option for Windows: a key in ID and KEY format with a lifetime license as stated by the seller, region-free activation and instant delivery. Per the listing, the key activates up to version 4.6.xx, after which the app can be updated to the current version. Account access is not provided; before reinstalling the OS or moving to another PC, deactivate the key in the app and activate it again.
A one-year key or a perpetual license
A dated (subscription) key is valid until a specific date and updates normally for the whole term; once it expires, you need a new key.
A perpetual license is a one-time purchase with no renewals — but “perpetual” refers to the license, not the program version: both Malwarebytes perpetual keys are tied to the 4.6.x branch, with update terms described on the card. If you want the latest version at all times, pick a dated key; to cover one PC once, the perpetual format saves on renewals.
And a Standard-card condition: deactivate the subscription before reinstalling the OS — the seller guarantees one activation, otherwise license access is lost.
