Bitdefender and AVG delivered an exact tie in AV-TEST’s August 2026 Windows 11 evaluation: each reached 6/6/6 for protection, performance and usability. That means the deciding factor is not a headline lab score but the tier you need. AVG Antivirus Free covers core malware, phishing and unsafe-link threats at no charge, while Bitdefender Free is a basic Windows antivirus with an optional Premium VPN upgrade. Paid products add broader web, ransomware, privacy, device and bundled-tool features, but their prices and renewal terms differ.
For a single Windows PC that needs baseline protection, either free product can be reasonable. Choose AVG when its free phishing, download and attachment safeguards meet your needs; choose Bitdefender when you specifically want its Windows free client or plan to move to a broader paid, multi-device subscription. Compare the exact product version, device allowance and renewal price before purchasing.

Neither wins outright. The products tie in the latest cited Windows 11 laboratory test, while their free and paid tiers serve different purposes.
| Question | AVG | Bitdefender |
|---|---|---|
| What is free? | AVG Antivirus Free, with malware, phishing, unsafe-link, download and attachment protection plus real-time updates | Bitdefender Free, a Windows antivirus using the company’s core technologies; Premium VPN is an optional upgrade |
| What was tested by AV-TEST in August 2026? | AVG Antivirus Free 26.6 and 26.7 | Bitdefender Total Security 27.0 |
| Protection, performance and usability score | 6, 6, 6 (18/18) | 6, 6, 6 (18/18) |
| Paid expansion | Internet Security; Ultimate bundles Internet Security, Secure VPN and TuneUp | Total Security, a paid product tested in the comparison, with broader subscription features and multi-device positioning |
| US device figure stated in the evidence | 10 devices for Internet Security and Ultimate | Not stated |
The practical split is simple: AVG Free is more explicit about the protections included in its no-cost tier, whereas Bitdefender’s free product is described primarily as a Windows antivirus. Paid plans should be judged by their included controls and the total cost after the introductory term, not by the free-versus-paid label alone.
#1 Best Overall
How did Bitdefender and AVG score in AV-TEST’s August 2026 test?
They received identical category scores. AV-TEST lists AVG Antivirus Free versions 26.6 and 26.7 and Bitdefender Total Security 27.0 with 6 points for protection, 6 for performance and 6 for usability—18 points out of a possible 18 for each product.
| Product and version | Protection | Performance | Usability | Total |
|---|---|---|---|---|
| AVG Antivirus Free 26.6 | 6 | 6 | 6 | 18/18 |
| AVG Antivirus Free 26.7 | 6 | 6 | 6 | 18/18 |
| Bitdefender Total Security 27.0 | 6 | 6 | 6 | 18/18 |
AV-TEST says products reaching at least 17.5 points receive its “TOP PRODUCT” award, so all three listed entries clear that threshold. The result is a dated snapshot of the specified Windows 11 builds, not a guarantee that every future update or platform will perform identically.

1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitchesA separate April 2026 AV-Comparatives performance report gives an important qualification: its results apply only to the specific versions listed, and vendors offer different feature sets and different numbers of features. In other words, you cannot transfer a score from Bitdefender Total Security to Bitdefender Free, or from a tested AVG build to every AVG edition, without checking the tested name and version.
What does AVG Antivirus Free include?
AVG’s free tier is aimed at everyday Windows threats rather than a complete privacy or maintenance suite. AVG describes it as protection that stops viruses, spyware and other malware, blocks unsafe links, downloads and email attachments, and receives real-time security updates.
- Malware defense: viruses, spyware and other malware are the core coverage.
- Web and message checks: unsafe links, downloads and email attachments are blocked.
- Live updates: the product is designed to receive real-time security updates rather than relying on occasional manual downloads.
- No bundled VPN or TuneUp entitlement is stated: those tools appear in the separate Ultimate bundle, not in the free-product description.
That scope can be enough for a user who wants a no-cost real-time antivirus and already has separate privacy, backup and performance habits. It does not establish that every premium network, ransomware or privacy control is present in the free edition; those boundaries are why AVG sells Internet Security and Ultimate.
What does Bitdefender Free include?
Bitdefender Free is presented as a free Windows antivirus built on the company’s core technologies. The product information also presents Premium VPN as an optional upgrade, so VPN service should not be assumed to be included in the free antivirus itself.
The Tool Desk
Outbyte PC Repair FREEClear out junk files and repair common Windows errorsFree Scan →Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →- Platform: the free product is specifically described for Windows.
- Protection model: it is a basic antivirus product using Bitdefender’s core technologies.
- VPN boundary: Premium VPN is an upgrade path, not a stated component of the free antivirus.
The available product description does not give a device count or promise the same feature list as Total Security. If you need coverage for phones, Macs or several household PCs, inspect the paid subscription’s current platform and device terms instead of assuming the free Windows client scales across them.
What is the difference between AVG Free and AVG Internet Security?
AVG says Internet Security includes every feature in AVG AntiVirus Free and adds premium protections. The US store listing identifies a 10-device plan and names Wi-Fi verification plus unsafe-site and phishing protection among the paid offering’s protections.
| Capability | AVG Antivirus Free | AVG Internet Security |
|---|---|---|
| Core malware protection | Included | Included, because the paid edition includes the free features |
| Unsafe links, downloads and attachments | Included in AVG’s free description | Included, with premium protections added |
| Wi-Fi verification | Not stated as part of the free description | Listed by AVG’s US store |
| US device allowance | Not stated | 10 devices |
| VPN and TuneUp | Not stated | Not part of the Internet Security name; both are listed in Ultimate |
There is an apparent overlap in the wording around phishing and unsafe sites: AVG’s free product already advertises blocking unsafe links, while the paid store listing also names unsafe-site and phishing protection. Treat the paid layer as an expanded or premium implementation, and verify the current feature description in your region before paying solely for that label.
What does AVG Ultimate add?
AVG Ultimate is a bundle rather than simply a higher malware-detection setting. AVG’s US store describes it as Internet Security together with Secure VPN and TuneUp for 10 devices.
- Internet Security: the paid antivirus and its premium protections.
- Secure VPN: a privacy tool bundled in the Ultimate plan.
- TuneUp: a performance and maintenance tool bundled in the same subscription.
- Ten-device coverage: the US listing applies the bundle to 10 devices.
Ultimate makes sense only if you would otherwise buy or use both a VPN and a maintenance utility. If you want only antivirus controls, Internet Security avoids paying for tools you may not use.
How does Bitdefender Total Security differ from the free product?
Total Security is the paid Bitdefender product represented in the August 2026 AV-TEST comparison. The editorial evidence characterizes paid Bitdefender plans as adding broader web, ransomware, privacy and multi-device capabilities, but it does not provide a complete current feature matrix or a universal device count for every market.
Rank #3
- Broader protection scope: paid tiers are positioned beyond the basic free Windows antivirus, including web, ransomware and privacy-oriented controls.
- Multi-device positioning: the subscription is intended for more than one device, subject to the plan’s current terms.
- Version-specific scoring: the perfect AV-TEST score belongs to Total Security 27.0, not automatically to Bitdefender Free.
- Renewal disclosure: Bitdefender explains that discounts compare first-term and renewal pricing and provides renewal notifications.
Before checkout, open the plan’s regional page and record the supported operating systems, number of devices, first-term price, renewal price and auto-renewal setting. Those details determine whether Total Security is a better value than AVG Internet Security or Ultimate for your household.
Which antivirus has the lower long-term price?
AVG’s US store provides concrete first-year and renewal figures; the supplied Bitdefender plan information describes subscription pricing and renewal notifications but does not state a comparable dollar amount. Therefore, a fair price comparison must show AVG’s published figures and leave Bitdefender’s amount to the checkout page for your region.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
| Plan | First-year price shown by the US store | Renewal price shown | Devices | What is included |
|---|---|---|---|---|
| AVG Internet Security | $59.88 for the first year | $99.99 | 10 | Free-tier features plus premium protections, including the listed Wi-Fi and web safeguards |
| AVG Ultimate | $59.88 for the first year | $149.99 | 10 | Internet Security, Secure VPN and TuneUp |
| Bitdefender Total Security | Not stated in the supplied plan information | Not stated; Bitdefender explains that discounts compare first-term and renewal pricing | Not stated | Paid subscription with broader feature and multi-device positioning |
AVG’s first-year figures are introductory prices displayed for the US market in 2026, not permanent rates. The renewal amounts are the recurring prices shown alongside those offers. A low first term can become the more expensive choice after renewal if you do not need the bundle, so calculate at least two years of ownership before deciding.
For either vendor, read the renewal notice and account billing page before the first term ends. Save a screenshot or receipt showing the plan, device count and renewal amount; store pages and promotions can change by country and date.
Is AVG Free good enough in 2026?
It is a defensible choice for a Windows user who wants real-time malware protection, phishing and unsafe-link blocking, download and attachment checks, and does not need a bundled VPN or maintenance suite. Its 6/6/6 AV-TEST result in the cited August 2026 Windows 11 test confirms strong performance for that tested build.
Move to a paid product when one of these requirements applies:
Recommended Free Tools
- You need coverage for several devices under one subscription.
- You want premium network or web controls beyond the free description.
- You need a VPN or maintenance utility bundled with antivirus.
- You specifically require paid-plan privacy or ransomware features.
- You want a vendor’s broader support and subscription management rather than a basic free client.
A free antivirus is not a substitute for operating-system updates, browser updates, backups and cautious handling of unexpected links. The lab score measures the tested product; it does not remove the need for those safeguards.
When should you choose Bitdefender instead?
Bitdefender Free is the more direct fit when you want a Windows-only free antivirus built on Bitdefender’s core technologies and may later add Premium VPN. Total Security becomes relevant when you need a paid, broader subscription and its current device and platform terms fit your household.
Choose Bitdefender Free when
- Your priority is a basic Windows antivirus rather than a bundle of utilities.
- You prefer Bitdefender’s product ecosystem or may add its Premium VPN separately.
- You are comfortable checking each paid feature instead of assuming free and paid editions are identical.
Choose Bitdefender Total Security when
- You need the paid product tested as version 27.0 in the cited AV-TEST result.
- You want broader web, ransomware, privacy and multi-device capabilities.
- You have confirmed the current renewal price and supported devices in your market.
Which plan fits common household situations?
| Your situation | Most sensible starting point | Why | Check before installing |
|---|---|---|---|
| One Windows PC, no VPN requirement | AVG Antivirus Free or Bitdefender Free | Both have a free path; AVG states more specific web and attachment protections, while Bitdefender is a basic Windows client | Confirm that the free installer offers the controls you expect |
| Several devices needing one subscription | AVG Internet Security, AVG Ultimate or Bitdefender Total Security | Paid plans are the relevant tier; AVG’s US listings state 10 devices | Verify operating systems and exact device limits |
| Antivirus plus VPN | AVG Ultimate or Bitdefender with its Premium VPN upgrade | Ultimate explicitly bundles Secure VPN; Bitdefender presents Premium VPN as an optional upgrade | Compare VPN limits, renewal prices and whether every device is covered |
| Antivirus plus maintenance tools | AVG Ultimate | TuneUp is included with Internet Security and Secure VPN | Do not pay for TuneUp if you will not use it |
| Lowest recurring cost after a promotion | Free tier, or the paid plan with the lower verified renewal | AVG’s listed renewals differ substantially between Internet Security and Ultimate | Use the renewal figure, not the first-year discount, in your calculation |
How do you switch from one antivirus to the other safely?
Install only one product’s real-time engine at a time. A clean changeover reduces conflicts, duplicate notifications and performance problems.
- Record your subscription details. Note the product edition, activation account, device allowance and renewal date before removing anything.
- Update Windows and back up important files. Antivirus software cannot recover files that were never backed up.
- Remove the old antivirus. In Windows 11, open Settings > Apps > Installed apps, select the existing antivirus, choose the uninstall option and restart when prompted. If the vendor supplies a separate removal utility, use it only from the vendor’s official support channel.
- Download the replacement from its official product page. Avoid installers bundled with search tools or unrelated utilities.
- Complete the installation and allow definition updates. Keep the computer connected until the first update and initial scan finish.
- Run a full scan. Quarantine anything detected, then restart if the program requests it.
- Check Windows Security. Confirm that one real-time antivirus is active and that firewall and security notifications are not being silently disabled.
- Review renewal settings. Verify the plan name, number of protected devices and the next billing amount in the account portal.
If the new installer says another antivirus is still active, restart once and remove the old product’s remaining entry. Do not manually delete security-driver files; use the vendor’s supported cleanup process.
What should you watch for with performance and upsell prompts?
The cited AV-TEST result gives both AVG’s tested free builds and Bitdefender Total Security a perfect 6 for performance and usability, so neither has an evidence-based disadvantage in that test. It does not measure every interface, notification or promotional message a user may see after installation.
During the first week, check whether scans run when you are working, whether browser protection blocks legitimate sites, and whether upgrade notices interrupt routine tasks. Record the exact version and edition when reporting a problem; AV-Comparatives warns that performance findings apply only to the listed versions. A prompt to buy a VPN or premium module is not proof that the free antivirus is malfunctioning—verify which feature generated it and whether you actually need that feature.
How should you interpret “perfect” antivirus scores?
An 18/18 score means the tested build achieved the maximum points across AV-TEST’s protection, performance and usability categories. It does not mean every product in the same brand family received the same test, nor that the score applies to macOS, Android or a later Windows build.
- Match the product name exactly: AVG Antivirus Free is not AVG Internet Security, and Bitdefender Total Security is not Bitdefender Free.
- Match the version exactly: the cited entries are AVG 26.6/26.7 and Bitdefender 27.0.
- Match the operating system: the comparison is for Windows 11.
- Use current release notes and plan pages for features, because laboratory protection scores do not describe billing, VPN limits or device coverage.
What is the final decision rule?
Start free if your needs are limited to baseline Windows malware and web protection. AVG Free is the clearer fit when its stated phishing, unsafe-link, download and attachment controls cover your use; Bitdefender Free is the straightforward alternative for a basic Windows client. Pay only when you need the added controls, multi-device coverage or bundled VPN and maintenance tools, then compare the second-year renewal—not just the promotional first term.
Frequently Asked Questions
Can AVG Free protect email attachments?
Yes. AVG’s free-product description specifically includes blocking unsafe email attachments, along with unsafe links and downloads. Keep your mail app and operating system updated as an additional safeguard.
Can I run AVG and Bitdefender together for extra protection?
Do not run two full real-time antivirus engines simultaneously. Remove or disable the existing product before installing the replacement, then confirm in Windows Security that only one real-time provider is active.
Why can two products from the same company have different test results?
Independent tests are tied to a named edition and build. A score for Bitdefender Total Security 27.0, for example, does not automatically describe Bitdefender Free, and AVG 26.6/26.7 results do not cover every AVG edition.
Does AVG Internet Security include the VPN?
The cited US plan descriptions place Secure VPN in AVG Ultimate, which also includes TuneUp. Internet Security is the antivirus plan; check the current regional listing if a VPN is essential to your purchase.
What should I do when my introductory antivirus price is about to renew?
Open the account billing page before the renewal date and verify the next charge, device count and auto-renewal setting. Compare that recurring amount with the free tier and competing paid plans before allowing the subscription to continue.
