Avast Business Antivirus 19.3
« on: April 09, 2019, 05:25:08 PM »

Avast Business Antivirus version 19.3 has just been released today (9th April 2019).

This release contains new improvements and bug fixes to our Avast Business Antivirus client.

Client Updates

Avast Business Antivirus 19.3 will be available for new installations on April 9, 2019. All existing devices with Avast Business Antivirus 18.8 or lower will start the automatic upgrade to 19.3 at a later time.

If you wish to upgrade your devices to 19.3 prior to the automatic upgrade, then you can create a new Task (Update device – Program update task) from your console.

A system reboot will be required, however, the user can postpone the reboot. There will be no forced reboot of devices.

This new Antivirus version will be available for client devices connected to our Avast Business Cloud/On-Premise consoles and un-managed version.


We now offer a 64-bit version of our Avast Business Antivirus client. Some benefits to this include:
-   Faster boot time
-   Reduced size of VPS files
-   Reduced installer file size
-   Faster scanning of mapped files
-   Support ARM64 build in the future

- Redesign of the Smart Scan UI
- We’ve hidden some new advanced settings— just search for ‘geek:area’ in your settings
- A safer UEFI - Anti-rootkit scan now protects your UEFI (unified extensible firmware interface)
- We’ve updated the look of our Custom Scans screen
- We’ve simplified our settings screens and even added direct links from our feature screens to their settings
- We’ve added a search bar to our settings to make it easier to find what you need
- Our Firewall’s network detection is now better than ever

Bug Fixes

• Remote Deployment will now display over 1000 devices from Active Directory
• Fixed high CPU usage on Windows 10 devices
• Improved the syncing speed of our tray icon
• Made our Outlook plugin work again on x64 systems running x86 Outlook
• Thawed out an annoying UI freeze some of you were experiencing
• Possibility to edit exceptions
• Fixed our boot-time scan
• Made sure our UI loads correctly ("white UI" problem)
• Fixed a bug for our users in Russia where Passive Mode sometimes turned on for no reason
• Boot-time scan results can now be found in scan history
• Fixed improper arrangement in our Web Shield detection (threat type and URL were switched)
• Settings can now be backed up and restored again (recommended for un-managed devices)
• Behaviour Shield exclusions now accept additional character form
• Default network is now set to Public in Firewall
• avastsvc.exe will no longer delete local proxy information

I just updated few servers and workstations. Everything is OK except for one computer with 32-bit Windows 7 Pro, where UI service did not started. Uninstall and reinstall fixed it.

After update, several machines on the network have an issue.   Avast keeps scanning the tmp file folder under Program Data.   The popup is very annoying and occurs every 30 seconds or so.   I have been unsuccessful at stopping the popup, even after trying Silent Mode, adding exclusion to that folder, stopping Self Defense Mode, restarting machines, using auto fix feature, rerunning update......Any suggestions to stop this would be much appreciated.
