Frequently Asked Questions from Customers

Yes, Bitdefender is considered one of the most secure and reliable antivirus programmes on the market.
It regularly achieves top scores in independent tests (such as AV-TEST and AV-Comparatives) for malware, phishing and ransomware detection, and is available for Windows, macOS, Android and iOS.

Here are the key points that make Bitdefender a reliable choice:

  • Very high malware detection rate

    • Detects and blocks viruses, Trojans, spyware, ransomware and zero-day threats.

    • In independent tests, it often achieves results close to 100% in real-world protection.

  • Multi-layered real-time protection

    • Advanced Threat Defense: analyses application behaviour and blocks suspicious activity (e.g. encryption attempts typical of ransomware).

    • Web Protection & Anti-Phishing: blocks malicious websites, dangerous links and phishing pages before they can harm you.

    • Advanced Firewall: adds a layer of protection to your home or business network.

  • Extra features for sensitive operations

    • Bitdefender SafePay: secure environment for home banking and online payments, to reduce the risk of data theft.

    • Ransomware protection with recovery (on Windows): blocks encryption attempts and, in some cases, allows you to restore your files.

  • Frequent updates

    • The security engine updates automatically several times a day, so you are also protected against new and emerging threats.

  • Low impact on performance

    • Much of the processing is done in the cloud: on modern PCs, Bitdefender is lightweight and unobtrusive, even during scheduled scans.

As with any software:

  • No antivirus can guarantee 100% security, but Bitdefender is among those with the highest level of protection.
  • On very old or low-performance PCs, it may be a little heavier, especially with all features enabled, but it is generally manageable with the right configuration.
  • Some features (e.g. VPN included) have traffic limits or are more basic than dedicated external solutions.

Overall, in terms of reliability and security, Bitdefender is considered a top-of-the-range choice in the antivirus sector.

When you purchase Bitdefender from Mr Key Shop, in addition to the security of the product itself, you also have the guarantee of a reliable purchase channel:

  • 100% original and verifiable Bitdefender licences.

  • Immediate digital delivery via email with original activation key, secure link to download the software, step-by-step instructions for installation and activation.

  • Secure payments (including PayPal and other secure methods).

  • Free technical support in Italian and English in case of problems with download, installation or activation.

  • 100% digital model: no physical boxes, with a lower environmental impact.

If you purchase it through Mr Key Shop, you also have the certainty of a genuine licence, secure download links and free assistance throughout the activation process.

Bitdefender is considered one of the best antivirus programmes available, both in independent laboratory tests and in user reviews. It offers very high protection, many extra features and a user-friendly interface, suitable for both beginners and advanced users.

Bitdefender's main strengths

Excellent protection

  • Near-perfect detection of viruses, malware, ransomware, phishing, and zero-day threats.
  • Often achieves the highest scores in independent tests (AV-TEST, AV-Comparatives, etc.).

Full suite of features (in paid versions, e.g. Bitdefender Total Security)

  • Advanced firewall

  • Webcam and microphone protection

  • Safepay for secure payments and home banking

  • Vulnerability scanning, anti-spam, parental control, anti-tracker, password manager, etc.

Light impact on the system

  • Many analyses are handled in the cloud, so Bitdefender does not slow down your PC too much during normal activities.

  • Scheduled scans are usually manageable even while you are using your computer.

Easy to use

  • Clear dashboard, automatic profiles (work, gaming, movies), guided settings for non-experts.

To install Bitdefender, you need two things:

  1. A valid licence (activation key or code)
  2. A Bitdefender Central account (free)

At Mr Key Shop, you will receive via email:

  • the Bitdefender licence key
  • a secure link to download the software from the official source
  • step-by-step installation and activation instructions

1. Preparing for installation

  • Check your email from Mr Key Shop: you will find the licence key and the secure link to download Bitdefender.
  • Uninstall any other antivirus software: it is recommended to remove other security software to avoid conflicts.
  • Check your internet connection: Bitdefender downloads additional files and updates during installation.

2. Log in to Bitdefender Central

  • Log in with your Bitdefender account or create a new one by entering your email address and password.
  • Once logged in, go to the “My Subscriptions” section.

3. Add the Bitdefender licence purchased from Mr Key Shop

  • In Bitdefender Central, click on ‘Activate code’.
  • Enter the licence key received from Mr Key Shop.
  • Confirm: the subscription will be linked to your Bitdefender Central account.

4. Download and installation on PC (Windows / Mac)

  • From Bitdefender Central, click on ‘Protect this device’.
  • Select the product (e.g. Bitdefender Total Security) and then ‘Download’.
  • Open the downloaded file (.exe on Windows, .pkg/.dmg on Mac).
  • Follow the on-screen instructions and accept the terms and conditions, wait for the add-ons to download, and then complete the installation.
  • Once finished, log in to the programme with your Bitdefender account: activation will be automatic thanks to the associated licence.

5. Installation on other devices (PC, Mac, Android, iOS)

If your Bitdefender plan covers multiple devices:

  • From Bitdefender Central, select “Protect other devices”.
  • Send the installation link via email or scan the QR code from the device you want to protect.
  • Open the link on the device, install the Bitdefender app and log in with the same account: the licence will be recognised automatically.

6. After installation: what to do

  • Run a first full scan of the system.
  • Check that real-time protection, firewall and web protection are active.
  • If you have purchased a full version (e.g. Total Security), also configure:parental control, Safepay for home banking and online payments, and any VPN included in the plan.

A valid Bitdefender activation code can only be obtained through reliable channels: the official Bitdefender website, authorised retailers and specialised stores such as Mr Key Shop, which sell original licences that can be legally activated through Bitdefender Central. Always avoid unknown websites or offers that are ‘too good to be true’, as the risk of invalid or revoked keys is very high. I have already purchased Bitdefender but cannot find the code: where can I retrieve it?

If you have already purchased a licence and cannot find the activation code, check the following:

  • Order confirmation email

  1. Check all folders: Inbox, Spam, Promotions, Junk.
  2. The code is often in the confirmation email with a subject line similar to ‘Order Confirmation’ or ‘Bitdefender Licence’.

  • Bitdefender Central account

  1. Go to central.bitdefender.com and log in with the same email address you used for the purchase.
  2. In many cases, the licence is already linked to your account and you can manage the product without manually entering the code.

  • Customer account on Mr Key Shop (if you purchased here)

  1. Log in to your personal area on Mr Key Shop.
  2. Go to the orders section: you will usually find both the activation code and the download link for the product.
  3. If you have any doubts, you can contact free support by providing your order number and email address.

To avoid ending up with a Bitdefender code that does not work or is deactivated, be wary of:

  • keys sold on unknown websites or without clear company details;

  • offers of ‘lifetime’ licences at ridiculously low prices;

  • private sellers on auctions and marketplaces (e.g. random ads, anonymous accounts).

Can't decide? Here's how to choose your digital shield in 2026 based on your habits:

  • Choose Bitdefender if: you are looking for an antivirus that does not affect game frame rates or rendering speed in AutoCAD. It is unbeatable for automated protection (Autopilot mode) and defence against SMS phishing thanks to Scam Copilot.
  • Choose Kaspersky if: you want granular control over privacy and Dark Web Monitoring. It is the ideal solution if your priority is total protection for children (Safe Kids) and advanced digital identity management.

No. Thanks to Bitdefender Photon™ technology, the antivirus adapts to your hardware specifications. If you are using heavy software such as Office 2024 or rendering programmes such as AutoCAD, Bitdefender modulates the scan load so as not to affect performance, ensuring maximum fluidity even on older devices.

In the Standard versions (such as Antivirus Plus or Total Security), Bitdefender includes a VPN with a limit of 200 MB of daily traffic per device. If you want to browse without limits, download large files anonymously, or stream content, we recommend the Bitdefender Premium Security plan, which includes unlimited VPN.

It is one of the most important innovations of 2026. Scam Alert actively monitors SMS, WhatsApp messages and system notifications on your Android or iOS smartphone. If you receive a fraudulent (phishing) link, Bitdefender instantly blocks it before you can even click on it, protecting your bank account and personal data.
