Hi all,

New beta version is here: AVAST 2015 R3 Beta 1 (build number 2015.10.3.2219)

  • Grimefighter is now redone and called Cleanup.
    - runs without need of reboot
    - much faster
    - free for beta testers
    - runs on more devices (better compatibility)
  • Improved Windows 10 compatibility
  • Ability to check compatibility issues with other antivirus software
  • Host-based intrusion prevention system (HIPS): an installed software package which monitors a single host for suspicious activity by analyzing events occurring within that host
  • StreamFilter with Secure DNS is now available also for Windows XP/Vista
  • NG is not using Volume Shadow Copy Service anymore
  • Beta version will now be updated automatically once new beta version released

Known issues:

  • SafeZone not working
  • Scheduler for Cleanup doesn't work
  • Sandbox doesn't work on Windows 10

Please test the following scenarios:

1. Run Cleanup either via Scan->Scan for performance issues or via Smart Scan, clean your HDD, optimize registry
2. Try to run Cleanup on machines where GrimeFighter couldn't run in past
3. Install Avast on the latest public build of Windows 10
4. Install Avast on machine where is already running some other antivirus - you should get some warning during installation
5. Run Smart scan on machine with more antiviruses, smart scan should show you some compatibility warning with offer to remove the other AV (currently we detect just some AVs). If detected try to uninstall them.
6. Try browsing on https sites + turned on SecureDNS on machines with Windows XP or Vista
7. Play with it as much as you can and please report any problems you find ;-)

How to install:

1. If you have installed some beta version before you can update it to this latest version via Settings->Update->Program.

2. Or you can download and install from here:

How to provide feedback
Please for specific issues set a new topic in the Beta section ( For general open discussion feel free to use this thread.

Avast cleaner:

It should be possible to install this version on top of your existing avast! installation (all settings should be preserved).

To report BSODs, crashes or any other none trivial problems please use new SupportPackage generating tool.

Instructions how to use it can be easily found:

We are looking forward for your feedback!

Thank you
Avast team

Host-based intrusion prevention system (HIPS): an installed software package which monitors a single host for suspicious activity by analyzing events occurring within that host <-- is this new ? I'm using Avast Free and I didn't notice this :/

and read your status, in the next update? ok, but behavior shield need some improvements because have a lot of problems like in your post.

I think they have a big gun in stock for their 2016 versions :)

Like automatically generated Dyna-Gen sigs or something else like that
if you think that... I hope that 2016 version come witha lot of improvements in detection and block suspicious files.
it's time to polish its technology like dyna-gen and others...


Level 18
I think that HIPS consolidates all others technologies and improve detections results, cloud response much more faster...its good for all,for the avast company and for their users:)

Well seems fine to incorporate HIPS which totally very complex and needs a train eye user, good thing if they will incorporate decision making based alert on which users answer on those pop ups as reference basis.


Very good news for Avast users :) I hope it will be implemented in free version.
Avast will be best "real" antivirus solution :)

Browser Protection, Software updater, Remote assistance, SecureLine, Cleanup(GrimeFighter), Rescue Disk, Browser Cleanup, Home Network Security and secure virtual machines :)

A lot of bloatware, but they have finally made GrimeFighter compatible with Windows 8 or higher. I will try the Beta with only File and Web Shield, the rest isn't needed for minimum protection.

Bundled Skype offer, even in the BETA Program.



Staff member
And since when was that more important during a BETA product phase?

Please test the following scenarios:
0. Install the Skype offer during installation.
Avast sells products to businesses as well as customers, it's not their only source of revenue. Once again, it's a free product.
