New beta version – build 26.2.10761

Hello everyone,

there is a new beta version ready - build 26.2.10761.

Release notes

[+] What is New (Windows)

Installer & Updates

  • Smoother upgrades and migrations: Installing or upgrading suites now handles older versions and multiple installed tools more reliably, reducing error dialogs and repeated restarts.
  • Cleaner uninstall experience: Uninstall flows have been simplified, with clearer final screens and fewer legacy questions or surveys.
  • Use of latest setup interface: The installer now uses the most recent interface package during setup, so even fresh installs benefit from current visuals and behavior.

Shopping & Subscriptions

  • In‑app cart auto‑fill: The in‑app cart can now auto‑fill details where appropriate, making it faster and easier to complete purchases.
  • Smarter upsell and inbox tiles: Product tiles and inbox counters have been refined so that recommendations, trial information, and “add device” prompts show only when they are truly relevant.

Protection, Scanning & Engine

  • Improved detection windows: Security pop‑ups and detection dialogs were refreshed so that what was found and what to do next is easier to understand.
  • Stronger unpacking and archive support: The engine has been hardened across many archive and installer formats (ZIP, RAR, CAB, DBX mail stores, DMG/HFS images, Python and script installers, and various executable packers). This improves stability on damaged files and helps ensure more content is actually scanned.
  • Safer driver and kernel integrations: Several security checks and “unload” behaviors were added to low‑level drivers, so protection can react more safely to system changes and diagnostic tools.
  • More precise DNS and encryption handling: Network protection now better understands modern DNS and encrypted connection patterns, improving compatibility while keeping inspection and blocking effective.

Privacy, Browser & Identity

  • Unified privacy settings: Privacy‑related settings have been aligned across different parts of the app, so similar options look and behave consistently.
  • Improved browser extension experience: Integration with Avast/AVG secure browsers and standard browsers was updated so that extensions install and register more consistently with the security suite.

User Interface & Experience

  • Dark theme and visuals aligned with design system: Dark and light themes, dialogs and icons have been updated to follow a consistent design system across Avast and AVG on Windows.
  • Customizable window layout: The app responds better to resizing and layout changes, improving usability on different display sizes and resolutions.
  • Clearer troubleshooting options: A new “hardware network acceleration” toggle and other advanced settings make it easier to try performance‑related adjustments without guesswork.

Cleanup & Tools

  • Extended support tooling: Standalone support tools now cover more modules and configurations, giving support teams better information when diagnosing issues.
  • Improved orphaned‑file cleanup: When installations are interrupted (for example by a restart), the installer now cleans up more of its temporary files without touching active installs.

[✓] What Was Fixed (Windows)

Installer & Uninstall

  • Correct product names on final uninstall screens: The final uninstall screen now consistently shows the correct product name, even on machines where multiple products were installed.
  • Uninstall dialogs that stayed open or closed too fast: Cases where “setup finished” or repair dialogs closed immediately or behaved unpredictably have been fixed.
  • Migration from older setups: Installing newer suites over older setup technologies now requests and handles required restarts more cleanly, avoiding confusing error codes at the end of setup.
  • Registry and activation bookkeeping: Registry values that track which standalone apps are part of a suite migration have been corrected so suite license information is stored consistently.

Uninstall Surveys & Flows

  • Removed obsolete uninstall surveys: Legacy uninstall surveys that no longer provided value were removed, simplifying the uninstall flow.
  • Working privacy links in uninstall surveys: “Privacy Center” links in uninstall surveys now open the correct page.
  • Fixed scrollbars and layout in password dialogs: Password‑protected uninstall dialogs no longer show unnecessary scrollbars or clipped content.

App Interface & Messages

  • Clearer error and status text: Multiple messages and notifications were simplified to make it clearer what happened and what action, if any, is needed from the user.
  • Theme and color inconsistencies: Several theme‑related issues (such as dialogs not respecting design‑system colors) were corrected for a more consistent look.
  • Safer handling of missing or empty data in UI reports: The app and backend now avoid sending or accepting empty UI‑report payloads that previously caused hidden errors.

Reporting, Telemetry & Logging

  • Fixed “400” errors from event reporting: Telemetry events with missing or invalid fields are now filtered or corrected before sending, reducing failed requests and log noise.
  • Removal of bad cached events: Events that the backend permanently rejects are now removed from the cache, preventing repeated retries.
  • Improved shutdown and restart logging: When Windows is shutting down while the installer engine runs, this is now logged as a specific event, simplifying later diagnosis of interrupted installs.
  • More accurate configuration signature checks: Cases where downloaded configuration files produced spurious signature‑verification errors have been mitigated with better validation and logging.

Engine & File‑Format Handling

  • Safer unpacking of archives and packed executables: Many boundary checks and error paths were corrected across packers and archive handlers to prevent out‑of‑bounds reads/writes and to fail cleanly on corrupted data.
  • Correct handling of big‑endian and large files: Several places where sizes or offsets could be misread on certain architectures or for very large entries were fixed, preventing truncation or mis‑scans.
  • More reliable mail‑store and database processing: Logic used for mail stores and database‑like formats was corrected so messages and records are not silently skipped when headers are unusual but valid.
  • Better certificate and signature parsing: Signature‑verification routines now handle edge cases in ASN.1 and certificate chains more robustly, avoiding sporadic verification errors on malformed signatures.

Performance, Stability & Crashes

  • Reduced crashes in uninstall and setup UI: Rare crashes in the setup UI during uninstall or complex flows have been addressed.
  • More robust memory‑allocation handling: Components now react more safely when system memory is low, returning clear errors instead of crashing or silently dropping work.
  • Improved handling of extreme or malformed input: Decompression and script‑parsing routines were hardened so that deliberately malformed content is more likely to result in a clean error rather than instability.

Cleanup & Tools

  • Improved installer cleanup of temp folders: When previous installs left behind temporary content, new installs are now better at cleaning it up without interfering with active products.

[!] Known Issues (Windows)

The following issues are known at the time of this release. Some apply only to specific configurations or product combinations.

Installer, Updates & Modules

  • During change operations, different temporary folders may be created than expected, which can make log review more complex but does not affect the outcome of the operation.
  • After certain suite installs, an unexpected language ID may appear in internal configuration files; the app UI language itself remains correct.

Network Protection

  • In a few environments, firewall rules can lead to a temporary black screen when specific Windows apps are used, indicating an overly strict block rule.

Browsers, Extensions & Web Protection

  • Avast and AVG secure browsers may not always appear in certain “Extensions” or “Browsers” lists inside the app, even though they are installed and protected.
  • The Brave browser may be missing from some browser‑listing views and require manual checking.
  • In rare situations, websites may not load correctly when a web‑filtering component is installed but disabled, due to how traffic is still intercepted at a low level.
  • Some bank or dark‑theme tutorials and overlays do not perfectly match the current tile layout or theme, leading to minor visual mismatches.

UI, Themes & Interaction

  • Some settings tabs and dialogs do not automatically scroll or resize to keep content fully visible when opened from deep links.
  • Instant summary panes in certain feedback experiences may sometimes fail to load until retried.
  • Various tiles and overlays in dark layouts may not fully match the current design system, especially in tutorial or education screens.

Performance & Stability

  • Under heavy use, some users report high cache usage or multiple browser processes for privacy‑focused browsers, which can impact perceived performance.
  • Rare crashes have been seen in components that scan or manage web certificates; these are under investigation.
  • In some environments, auto‑update may be turned off after installation, requiring users to re‑enable it manually in settings.

Firewall & Remote Access

  • Firewall blocked‑packet logs may not always list every blocked connection, even though the firewall is actively blocking suspicious traffic.
  • For some unmanaged small‑business environments, Remote Access Shield does not record all connection attempts in its UI, even though blocking still occurs according to rules.

Enjoy this beta!
We are looking forward to your feedback.

AVG Team

The update mentions that dark and light themes are now aligned across Avast and AVG on Windows. I assumed the AVG beta would include the light theme too, but it’s not available. Is this expected behavior?
