New in version 10.0.2200 Beta 2 (September 20th, 2014)

  • AVAST NG:
  • A hardware based virtualization solution capable of running each Windows process in standalone safe virtualized environment (VM) and fully integrated to your desktop. Each process is executed in its own instance of VM, which means totally isolated from your other applications. This feature is now powering the Avast DeepScreen, resulting in better detection. The technology will also eventually power the Sandbox and SafeZone components (although it does not now).
  • Note: In this beta build, not all detections are 100% operable yet, so I wouldn't recommend using the new DeepScreen for detection testing for now. It will be 100% operable in the next couple of weeks - we will certainly let you know when is the good time to start testing with your malware collections.
  • Note 2: Avast NG can be installed only on physical machine, does not work in VM. It requires HW virtualization enabled.
  • GrimeFighter Free:
  • GrimeFighter will offer free cleaning of junk files and tuning of system settings. These tasks are performed by our Zilch and Torque minions. Other minion functions remain as paid-for features.

New in version 10.0.2021 Beta 1 (August 16th, 2014)

  • The UI hasn't changed a lot, but internally we are delivering you a lot of new for this new major version of AVAST:
  • HTTPS scanning:
  • Now, we are able to detect and decrypt TLS/SSL protected traffic in our Web-content filtering component. We are using our own generated certificates that are added into the Root Certificate store in Windows and also into major browsers. This feature will protect you against viruses coming through HTTPs traffic as well as adding compatibility for SPDY+HTTPS/ HTTP 2.0 traffic. You can tune/disable this feature in the settings section.
  • Home Network Security:
  • Scan your home network for vulnerabilities (wifi status, connected devices, router settings, factory passwords, etc.). This is quite a new approach as we are trying to discover potential problems not isolated on the particular device only, but in the entire network of devices you use or connect to the Internet from.
  • SecureDNS (this feature is active in the paid versions only):
  • We are introducing a new provider which guards against unprotected DNS/DNS hijack on a router/client (including unsecured networks, public ones, etc.).
  • Smart Scan:
  • Integrated all on demand scans into one (Antivirus, Software updates, Home Network, GrimeFighter). One scan, different results and recommendations.
  • New Support System:
  • Easy contact for paid users to submit a ticket with all info included automatically. Improved knowledge base for free users. Help is completely online and is more up to date.
  • General bugfixing:
  • This covers a lot of stability & performance changes in all components (but the main focus was traditionally on the network & engine components).

New in version 9.0.2021 R4 (June 27th, 2014)

  • We've improved the security of the product - e.g security of our processes (guarded by the self defense component), we handle the conditions for the Guest account better, we are very senstitive for any incorrect inputs from the user with a negative impact on the system's security, or, we tuned the import settings functionality not to allow bypassing any protections
  • We've added "resume" support in the setup component, so some of you should notice smoother downloading - depends on a "quality" of your connection (mainly during the program update where the amount of data is quite big)
  • We've included a new antispam library (IS/Premier editions) for better accuracy of our anti-spam module
  • We've put warnings during the installation process if there could be some obvious problems resulting in not 100% functionality after the installation (missing admin rights, insufficient space on disk, etc.)
  • We've added ability to disable promotion popups (in PRO/IS/Premier editions). We strongly believe that our additional products can be valuable for you, but we also respect your will not to be bothered by such offers.
  • We've performed a static analysis of our code resulting in many fixes (but don't worry, nothing was critical, just a small tuning
  • General bugfixing - this covers a lot of stability & performance changes in all components (but the main focus was traditionally on the network & engine components)

New in version 9.0.2020 R4 RC (June 24th, 2014)

  • Improved avastCleaner
  • Tuned text & graphics

New in version 9.0.2019 R4 Beta (June 17th, 2014)

  • We've improved the security of the product - e.g we handle the conditions for the Guest account better, we are very senstitive for any incorrect inputs from the user with a negative impact on the system's security, or, we tuned the import settings functionality not to allow bypassing any protections
  • We've added "resume" support in the setup component, so some of you should notice smoother downloading - depends on a "quality" of your connection (mainly during the program update where the amount of data is quite big)

New in version 9.0.2018 (April 18th, 2014)

  • Includes changes from the previous Beta version

New in version 9.0.2017 SP 1 Beta (April 8th, 2014)

  • Stream Filtering -- fixed stability and compatibility issues, it's running smooth and fast now, so no more browsing problems
  • Firewall -- the firewall should be more stable and with better compatibility with other network applications. we spent a lot time analyzing various dumps you provided to us to increase your confidence level.
  • Android protection - we can protect (if you wish) your Android phones and tablets with avast! Free Mobile Security (through your active Google Account) automatically (during the installation or update).
  • A lot of fixed issues you reported to us

New in version 9.0.2014 R3 Beta 1 (March 7th, 2014)

  • Improved: Browser Cleanup – improved detection and removal of browser protectors, those tools that try to block us from getting rid of annoying toolbars
  • Improved: GrimeFighter – now supporting 12 additional languages and with an advanced console for more control of optimization tasks. Go ahead and fight the Grime

New in version 9.0.2013 (January 23rd, 2014)

  • FIXED: Uninstalling avast might hang at "stopping service: avast! antivirus"

  • Performance and stabilization fixes in Stream Filter - e.g blocking of ajax calls
  • Several firewall fixes - e.g. blocking of Google Earth
  • Stability improvements - several crashes fixed

New in version 9.0.2012 Beta (January 16th, 2014)

  • What was fixed:
  • Uninstalling avast might hang at "stopping service: avast! antivirus"
  • Performance and stabilization fixes in Stream Filter - e.g blocking of ajax calls
  • Several firewall fixes - e.g. blocking of google earth
  • Stability improvements - several crashes fixed

New in version 9.0.2011 (December 17th, 2013)

  • Finally fully rewritten the WebShield so that it now doesn't work as a "transparent proxy" anymore. I.e. no more routing of all HTTP traffic through the AvastSvc.exe process - which should hopefully result in no more conflicts with various firewalls (especially older firewalls that can't handle transparent proxies) and overall improvement in stability and performance. Besides that (and this is really exciting) it allows us to see and detect more threats (the original webshield had some limitations).
  • The Firewall component (in IS and Premier) has also changed dramatically. Made it more compatible with other applications, such as Java and various VPN services.
  • The installer/updater has been improved to allow more reliable installation in case of infected machines. The installer is now protected by the avast self-defense driver from the very beginning, making it harder for active malware to kill it (if you have problems starting the installer in the first place, it may be a good idea to try to rename the executable to a random name first)
  • The changes in the File System Shield's driver should result in faster performance, especially in the copy files and install programs scenarios.
  • We have also beefed up the Browser Cleanup tool to be able to rip off even the more stubborn toolbars and other "PUBEs" (Pontentially Unwanted Browser Extensions
  • Also fixed a whole bunch of bugs reported in the last couple of months. Especially if you encountered a problem with R1, try this new version, chances are that the problem is resolved there.
  • For trialware users, an interactive tutorial that explains all the features of the product in a straightforward, concise manner has been added

New in version 9.0.2010 RC (December 13th, 2013)

  • Fixed reported BSODs related to the WebShield, Networkshield and FW
  • Browser plugin support in IE11
  • USB rescue disk creation sometimes fails (WinXP)
  • Added localizations

New in version 9.0.2009 Beta 1 (December 3rd, 2013)

  • GrimeFighter -- performs a scan to identify ways to speed up, clean up, and better protect your PC. GrimeFighter will run the scan and show you where you can improve the performance of your PC. It then sedates your PC and performs all of the cleaning functions. This need feature is a result of our acquisition of Jumpshot earlier this year.
  • SavePrice -- we added a new function to the browser plugins that helps you save money when you are shopping online. It finds better prices for items you are searching for. At the moment, Chrome, Firefox, and Safari are supported. Internet Explorer should be supported in the near future.
  • avast! tutorial -- for users who run avast! trials, a tutorial is now available explaining all the great things avast! can do to protect your PC
  • Stream Filtering -- a completely rewritten function that is part of the new Web Shield launched in v2014. The three main components of Stream Filtering are a rewritten scanner, new kernel mode inspection techniques, and a new HTTP parser. All of these functions lead to more effective detections of threats
  • Firewall -- most importantly, the previous issues with Java have been solved. The firewall should be more stable and with better compatibility with other network applications

New in version 9.0.2008 (November 11th, 2013)

  • Fixed issues with Metro apps (after update to Win 8.1)

New in version 9.0.2006 (October 16th, 2013)

  • Protection-related features and improvements:
  • New DeepScreen technology allows avast! to make more intelligent decisions about new/unknown files. DeepScreen is a successor of AutoSandbox, now upgraded with some additional new technologies such as dynamic binary translation and dyna-gen announced earlier.
  • New Hardened mode for stricter lockdown scenarios. This is a new mode that is recommended especially for novice users (such as your grandmas): it automatically blocks execution of binaries that would normally be deepscreened (Moderate level) or even allows only execution of programs that are well-known to FileRep (Aggressive level). In a way, it brings the whitelisting concept to the consumer AV space.
  • Improved cloud scanning features and crowdsourced analysis of suspicious items. This includes new, optimized mechanism for collecting data from our sensors.
  • Continuously streaming update (CSU) technology for up-to-minute detections. This is not entirely new for v2014, but we now have really buttoned up the whole streaming update infrastructure to allow for reliable, uninterrupted service. We’re currently doing 350-400 updates a day, which equals to one update in roughly every 3.75 minutes, 24x7, 365 days a year. Streaming updates can now also carry more types of definitions than before.
  • Improved cleaning of malware. This applies to standard malware as well as rootkits and file infectors.
  • Other new features:
  • All-new web browser plugins featuring comprehensive security ratings, protection against malware, phishing and typosquatting sites and Do-Not-Track (DNT) functionality for improved anonymity on the Internet. The DNT functionality doesn’t rely on the DNT HTTP headers; instead, it uses a proprietary technology that cannot be overridden by the servers.
  • All-new SafeZone for more secure online shopping and banking. Users can now switch back and forth between SafeZone and the regular browser with a single click. Also, online banking sites can be automatically opened in the SafeZone.
  • Rescue disk - allow users to create a bootable CD or flash disk with Avast on it. Great for cleaning.
  • Other improvements:
  • A new, streamlined user interface for simplified navigation and more user comfort. The new UI is actually much simplified, and it’s probably the biggest change since version 5.0. We have also redefined the shields to the total number of three (File Shield, Web Shield, Mail Shield) and tweaked the action buttons (tiles) on the home page so that they’re now fully configurable.
  • Control and manage all protected devices directly from the Avast console. That is, the my.avast.com account is perfectly integrated in the UI to allow for management of all your devices running Avast.
  • Dramatic reduction in product size (full installer < 60MB, compared to today’s 120MB) and memory footprint. By default, install is done through a new stub installer though (which has the advantage of always installing the most up-to-date version).
  • Faster scanning thanks to optimized scanning engine (raw [in-memory] scans of EXE files are about 2x faster, while scans of text contents (e.g. web pages and scripts) are up to 10x faster).
  • Completely rewritten setup/updater that makes the installation and upgrade process faster, easier and more reliable
  • Firewall has been redesigned from scratch to allow for better compatibility with latest Windows, better performance and full support for IPv6 (although its UI hasn’t really changed).
  • New licensing system allows for much easier management of product licenses. The system relies on activation codes, and these can be added seamlessly by simply clicking a link.
  • Various improvement in the Software Updater and Browser Cleanup tool.
