Changes in Avast 21.3.2459 Build 21.3.6164:

  • Improved Rescue Disk — added a portable web browser to our Rescue Disk so you can search the web even when Windows isn’t working
  • Fewer distractions — no longer show pop-up messages when your antivirus is open
  • Passive Mode fix — fixed a bug that would sometimes disable Passive Mode soon after it was turned on

Bug-fix and improvement highlights for hardcore fans:

  • Because of an expiring MS certificate for signing drivers, we had to block updates and installations of users with outdated/unpatched versions of Win7 (up to KB3033929). Unless they update their OS, they will stay on 21.2 version.
  • Implemented Countdown (auto-close) of Cyber Capture dialogs
  • Additional Rescue Disk improvements (postponing toolkit installation until MSI installation finishes, adding retries to downloading RCD files, etc.)
  • Fixed cases when both our Firewall and Windows firewall were running simultaneously
  • Fixed issue where the restart dialog didn’t appear in Silent Mode
  • Fixed issues where our uninstall survey was not displayed
  • Fixed issue when the UI didn’t show the correct state of IDP (Behavioral Shield) features
  • Some of those scan optimizations mentioned in our public release notes include: Startup, registry callbacks, behavioral events, on-exec DLLs scanning, identified opportunities to skip some scans, etc.)

Changes in Avast 21.2.2455 Build 21.2.6096:

  • Introducing Hack Alerts — From now on, we’ll warn you if any passwords linked to your email address were compromised in a hack or a leak. (Just sign in to Avast Account within antivirus)
  • New performance report tool — If you encounter any performance issues on your PC and you suspect we’re the culprit, you can now send us a report so we can investigate the issue (Just go to Settings > Troubleshooting > Record a performance problem)

Bug-fix and improvement highlights for hardcore fans:

  • AV DNS finally no longer conflicts with our VPN solution
  • Fixed product toasters that stole window’s focus
  • Arranged for the proper order of dialogs in various alert-dialog flows (for reporting false positives, when the main UI is open, etc.)
  • Fixed an issue where Passwords Protection (a Premium feature) was turned off for some users
  • Fixed some rare cases where user settings weren’t stored properly during product updates
  • Fixed rare problems with WebShield and HTTP/2 HPACK compression

Changes in Avast 21.1.2449 Build 21.1.5968:

  • More informative threat alerts — If you get an alert, click ‘See details’ to see what type of threat it is (e.g., adware, ransomware, scam, etc.) and a brief description
  • Tidier threat alerts — If you ever run into multiple threats at once, you’ll no longer be bombarded with one alert after another. Instead, we’ve combined these into a single alert according to the shield that detected them
  • New detection category — You can now choose to detect or ignore ‘Tools’ like coinminers, game cheats, and key generators as a separate category in your virus scans and core shields
  • Alert ID — Every threat alert now includes a unique ID in the bottom-left corner. If you ever share a screenshot with our support team, this ID will help them to identify your problem
  • Improved PUP detections— We’re now even better at identifying PUPs (potentially unwanted programs that often come bundled with other apps), so we’ve enabled PUP detection by default. (This will be rolled out continuously and not everyone will have it on straight away – so if you want to be in control yourself just go to Settings > Basic protection > Detections.)

Bug-fix highlights for hardcore fans:

  • Fixed compatibility issues with the latest version (2021) of JAWS reader
  • Patched Sandbox escape method (along with silent updates to previous AV versions)
  • Fixed some unwanted merging of old / default avast5.ini configuration
  • Fixed a rare bug that closed the UI when you changed the AV language
  • Silenced some background network scans in case they weren’t required
  • Arranged for a more thorough uninstall (BugReport file is no longer left over)
  • Implemented Remote Access Shield conflict warnings in Passive Mode
  • Fixed an issue where detection dialogs were stuck behind the main UI when opened
  • …and many other fixes and improvements

Changes in Avast 2020 20.10.2442 Build 20.10.5824:

  • Expanded Password Protection – We now protect your passwords in the beta versions of browsers, too. (Chrome, Edge, Firefox, and AVG Secure Browser – Premium Security Only)
  • Rescue Disk improvements – Windows 7 users can celebrate knowing this feature works for them again, and we’ve improved its performance and made sure it properly cleans up related .DLLs for all users
  • Bug stomping – Just the usual bug fixes that keep your antivirus going strong

Fixed bugs:

  • Restart PC dialogue no longer ignores the “Next century” reminder. (Just wait and see…)
  • Fixed driver incompatibility with HVCI (AV installation now works when Windows Core Integrity memory isolation is on)

  • More versatile Password Protection – Along with Chrome and Opera, we now support Microsoft Edge and, our personal favorite, Avast Secure Browser (Premium Security only)
  • Vote for features – Vote for your favorite premium features, or submit your ideas for new ones. Simply go to Menu > About and let us know your preference (Premium Security only)
  • Performance improvements – Your antivirus components should now load even faster thanks to simultaneous loading of our main service and VPS

And some other under-the-hood improvements:

  • Moved Do Not Disturb module to separate “tools” service for better performance
  • Minor accessibility adjustments (e.g., added tray shortcuts, improved confirmation dialogs when disabling shields, etc.)
  • Corrected some issues with Sensitive Data Shield on x86 systems
  • Sensitive Data Shield also now protects manually added files without having to restart your PC
  • Fixed minor bug so Behavior Shield doesn’t duplicate detections already covered by File Shield
  • Fixed a rare case where Firewall would trigger an ask dialog for already stopped processes
  • Fixed a rare case where switching languages could fail
  • Fixed some licensing hiccups with Cleanup and VPN wallet keys when being activated by AV
  • Optimized scanning of QUIC connections
  • …and about 100 others

Here are biggest improvements:

  • Improved accessibility – Our interface is now better suited for impaired users
  • Safer web browsing – Web Shield now supports scanning for threats in Google’s QUIC protocol

  • Better Remote Access Shield – Not only do we now support Windows’ Samba protocol, we’ve also added logs to show all remote connection attempts to your computer. (Avast Premium Security only)
  • Firewall recognizes VPNs – Firewall now knows when you’re using our VPN and won’t classify this as an unknown network. (Avast Premium Security only)

And here are just some of the 100+ issues we also fixed:

  • Stomped a pretty nasty UI bug that made AV pop up randomly
  • Edge case fixed where Password Protection didn’t recognize supported browsers
  • Text encoding of an exclusion created from detection dialog
  • Shredder can now properly shred read-only files
  • Fixed service crashes that happened when uninstalling the Wi-Fi Inspector component

  • Fixed OS boot problems when running smss.exe as virtualized
  • Plugged a memory leak in RegistryChangeWatcher
  • Fixed aswToolsSvc.exe initialization issues upon version update and before OS restart
  • Fixed serviceDLL monitoring and removal

  • Remote Access Shield detection window no longer appears if you’ve disabled its notifications in settings

Changes in Avast 20.7.2425 Build 20.7.5568:

  • Fixed shield statuses – The on/off statuses for Password Protection and Remote Access Shield are now properly reflected in your UI. (Avast Premium Security only)
  • Improved performance – Your antivirus now runs even smoother thanks to tighter integrations with the Windows registry and boot optimizations

  • The incorrect “expired” dashboard status after an upgrade from free to paid [AVG only]

Changes in Avast 20.6.2420 Build 20.6.5495:

New Features:

  • Simplified privacy settings – We’ve updated our privacy settings to make it easier to manage your privacy
  • Payment notification – If for any reason your payment fails during an automatic subscription renewal, we’ll now let you know on the main dashboard

  • Introducing Remote Access Shield – Enjoy even stronger protection against hackers. This new feature lets you choose who can remotely access your computer and lets you block the rest. (Premium Security users only)
  • Ransomware Shield is now free – We’re now offering this feature to Avast Free Antivirus users to maximize their ransomware protection
  • Easier USB drive protection – We’ll now ask you to scan USB drives when you plug them into your computer. (You can also turn this off in your notification settings)
  • Improved taskbar icon – There’s no need to keep your antivirus open during scans. You can now see your scan progress from the Avast taskbar icon
  • Better botnet protection – Web Shield is even better about stopping malware from connecting to malicious servers

Things to note:

  • We are no longer releasing new versions of Internet Security and Pro. Every Pro/IS user updated to 20.5 version will end up on Premium Security to enjoy the full feature-set of paid version.
  • Teaser for our dedicated forum users: We’ve added support for scanning Google QUIC protocol in Webshield, though it’s enabled only for some users at the moment. We plan to full scale it in the upcoming version.

…and from about 110 other smaller or larger tasks, we pick here the fixes of:

  • corner cases when Firewall was consuming too much CPU in correlation with VPS requests
  • Cleanup install detection upon switching to x64 version (Congrats to Cleanup team and sorry when the app was being offered to you even if you had it already)

  • Improved Wi-Fi Inspector – We’ve updated your Wi-Fi Inspector so that it’s a lot more stable
