GuardPick snapshot
The short version
Avast and AVG are effectively tied on protection. Avast One Basic offers more free extras; AVG AntiVirus Free is the less cluttered choice. Microsoft Defender is still my default recommendation for careful Windows users who do not need those extras.
Best for
Avast: users who want extra free network and ransomware tools. AVG: users who want a more focused third-party antivirus.
Avoid if
You already use Microsoft Defender comfortably and do not want another app, another set of prompts, or another privacy policy.
Main tradeoff
Avast offers more features, while AVG keeps the decision simpler. Their current independent protection results are the same.
Safer alternative
Microsoft Defender for careful Windows users, paired with browser updates, a password manager, and an offline or versioned backup.
Avast vs AVG is mostly a feature and interface decision, not a malware-detection decision. The latest independent Windows tests put them side by side with the same scores.
That does not make either product bad. It means the honest comparison should focus on what changes after installation: extra tools, prompts, account requirements, privacy terms, and whether replacing Microsoft Defender solves a real problem.

What the 2026 lab results actually show
Lab data context
Independent lab context
Lab data can be useful, but it is one input. It does not replace pricing, usability, renewal clarity, or your actual risk level.
AV-TEST
April 2026
What was measured
Protection, performance, and usability on Windows 11 using current public product versions and default settings.
Result summary
Avast Free Antivirus and AVG AntiVirus Free both received 6/6 in all three categories. Microsoft Defender also received 6/6/6.
What it does not prove
A perfect category score does not promise that every threat will be blocked or that the products behave identically on every PC.
GuardPick interpretation
There is no evidence here for choosing Avast over AVG on protection. Features and user experience should decide the tie.
AV-Comparatives
February-May 2026
What was measured
Protection against 400 internet-borne test cases, with false positives considered in award levels.
Result summary
Avast, AVG, and Norton each recorded a 99.3% protection rate and received the top Advanced+ award.
What it does not prove
A 99.3% result is not a guarantee of future protection. The report also says AVG and Norton use the Avast engine.
GuardPick interpretation
Avast and AVG again finished together. A claim that one has clearly better detection would overstate the evidence.
GuardPick does not run in-house malware tests. Use the named lab month/year to verify the source before treating any result as current.

Where Avast One Basic is better
Avast is the better free choice when you actively want the extra modules. Avast’s current support material lists antivirus scans, File Shield, Web Shield, ransomware protection, quarantine, and browser cleanup in the Basic tier. Some network and email features are limited rather than fully unlocked.
The downside is product breadth. A suite with more visible modules also creates more upgrade paths and more settings to understand. If you only want real-time antivirus, that breadth is not automatically an advantage.
Where AVG AntiVirus Free is better
AVG is the better choice when you want a narrower third-party antivirus experience. AVG says its free product includes real-time detection for viruses, malware, spyware, phishing, and other threats. Its paid Internet Security tier adds mailbox scanning and remote-access controls, while VPN and TuneUp remain separate subscriptions.
That separation makes the free-versus-paid boundary easier to understand. It does not give AVG a detection advantage.
The privacy history needs precise wording
The old draft treated the Jumpshot story as a 2020 news cycle and then speculated about current behavior. The stronger approach is to use the regulator’s final record.
The FTC finalized its Avast order in June 2024. In 2025, the FTC opened a refund-claims process for affected customers. Those are documented facts. Current Avast or AVG practices should be judged from current notices, settings, and future enforcement, not guessed from the historical case.
Marketing vs usefulness
What should decide the install?
Protection scores are tied, so the useful questions are about everyday friction.
More free features
Sounds useful because
Network checks, ransomware controls, and browser cleanup sound like more value.
Reality check
Some modules are limited, and a longer feature list creates more prompts and upgrade paths.
GuardPick take
Choose Avast only if you can name the extra feature you will use.
A simpler interface
Sounds useful because
Fewer modules make antivirus easier to understand.
Reality check
AVG still has a paid upgrade path and separate VPN/TuneUp products.
GuardPick take
AVG wins on focus, not on detection.
Replacing Defender
Sounds useful because
A third-party product may feel more protective.
Reality check
Defender matched both products in AV-TEST's April 2026 categories and is already integrated into Windows.
GuardPick take
Do not replace Defender unless Avast or AVG solves a specific need.
Which one should you choose?
Alternative path
The practical decision
Start with the least complicated option that covers the actual need.
- 01
Default for careful users
Keep Microsoft Defender
It is already included, tested well in April 2026, and avoids another vendor account and upgrade funnel.
- 02
Choose Avast if
You want the broader free toolbox
Avast One Basic is the more feature-rich free package, particularly around ransomware and basic network tools.
- 03
Choose AVG if
You want a simpler third-party antivirus
AVG AntiVirus Free is easier to explain: real-time antivirus first, with premium extras kept in paid products.
Protection is a tie. Pick the interface and feature model you prefer, or keep Defender if neither solves a problem you currently have.
Editorial method
How this comparison was checked
GuardPick compared current vendor documentation, the FTC's final enforcement record, and dated independent Windows lab results. We did not run an in-house malware test.
- 01
Real-world angle
We look at whether the product makes sense for normal Windows users, not only benchmark charts.
- 02
Independent research
When lab data is used, we name the source and date instead of repeating vague marketing claims.
- 03
Pricing check
Intro prices, renewal jumps, trial limits, and cancellation friction are part of the verdict.
- 04
Alternatives considered
Windows Defender and lower-cost options stay on the table when paid software is not necessary.
