Protecting over 200 million PCs, Macs, & Mobiles – more than any other antivirus

January 19th, 2010

Avast! Version 5.0 is here!!!

Today is the big day—the day we (and many of you) have been waiting for—we are starting the release of the Version 5.0 products today. This is a pretty complicated roll-out so we are staging it. Today we will be releasing the new products (and the new website) in English and French. Over the next 10 days or so, we will be releasing the products and website in additional languages (German, French, Spanish, Portuguese, Czech, Russian, Polish, Chinese, Japanese, and possibly Korean, and Arabic). Other languages will then be added as we have them available.

Three products (Free Antivirus, Pro Antivirus, and Internet Security) and a new website are being released today. Even though we have expanded our product portfolio, our philosophy of having and promoting a top-notch free antivirus is paramount. This philosophy has enabled us to achieve 100 million users and we are continuing it. As you read through our new website and launch information, you will see that not only is the new free product easier to use and more visually appealing than the old product, it provides even more security protection. And it is still free and free from annoying pop-ups and requests for money.

These products are not minor updates from the existing products. They are all new. Some of the changes—such as the new user interface—are obvious. Some are not obvious at all (such as the new scanning engine). All-in-all we think they are a vast improvement from the current products—modern, light, fast, and very effective. For details, see the product detail pages on the new website.

  1. Avast! Free Antivirus. This is our new flagship product and replaces Avast Home Edition (we changed the name to emphasize the product is free). We focus this product on users that use the internet for web browsing and email. If that is what you do on the internet, this is the product you need. We are very proud of this product and we stack it up against anyone else’s paid antivirus—in fact, we have recently started submitting this product in lieu of our paid products to all of the industry standard tests. Virus Bulletin, one of the most respected journals, recently called this product “….nothing short of a miracle” (see separate blog post). Google selected this product for incorporation in many of their Google Packs. You can download this product here:
  2. Avast! Internet Security. This is our brand-new product and is focused on users that do on-line banking or shopping or that have sensitive data on their computer. We believe that these users need some extra layers of protection and developed this product to provide three more layers. This product takes the free antivirus and adds a 2-way silent firewall, a sandbox, and anti-spam. The firewall ensures that only trusted applications are able to receive or send data across the internet. The sandbox provides a means of executing your browser (or any other application) in a protected environment—thus even if you get infected, the infection does not leave the sandbox and does not harm your computer. And the anti-spam helps you get rid of all that irritating email you receive every day. And, we have made this product attractive to consumer users—a single license can be used on 3 computers in your household. This link will take you to the product and download page:
  3. Avast! Pro Antivirus. This is the update to the old Professional Edition. We focus this product on individuals that want to customize their security and on businesses. It is the same as Internet Security but without the firewall or anti-spam. This allows world-class security using your own personal choice of firewall and anti-spam. Here is how to get this product:

To support these products, there is also a brand new website. Today the website will only be available in English and French. But, as the other languages roll out, the language-specific websites will also.

If you are using a 4.8 product (home or professional editions), the update is pretty painless.  Sometime in the near future, the 4.8 product will tell you version 5.0 is available.  You will have the choice of a free upgrade or a special existing-user offer for the new Internet Security. All you have to do is click which option you want, and you will be upgraded. As we have about 100 million users, these messages will take a month or two to get to all users. If you don’t want to wait for this automated message, you can manually upgrade and get the same special offers by clicking on the homepage banner that asks if you are already a 4.8 user.

As you can imagine, it was a massive effort to release three new products and a new website at the same time. All of our teams have done a great job in making this happen. Development of course developed the new products. But many other teams were also involved—virus lab and research, localization and translation, website development, on-line store, and marketing.

If you are reading this at launch time, we will think of you as we celebrate with the Czech national drink……

    Brilliant news, but would you recommend waiting for update offer or manual installation.

    I only ask because you say there is an upgrade offer for Internet Security, how do we get this offer, and what is the price?

  6. January 19th, 2010 at 18:38 | #6

    Hi Nick. The same offers are available on the website via the banner asking if you already have 4.8

    Great !

    Two small things about the new French website :
    -The favicon is still the old blue orb
    -The French translation of the website is not so great. Missing accents and capital letters, Google translations (if you see what I mean), missing links in the FAQ, …

    Nick, this will actually show up there tomorrow.

  11. January 19th, 2010 at 18:58 | #11

    I don’t see any Avast new website?

    I dont see new site ?

  13. Confused
    January 19th, 2010 at 19:35 | #13

    I’m not able to see any changes on the website. No new logo, latest version of home/pro listed as 4.8.1368… I’ve even deleted cookies before loading the page but nothing…
    Since I can’t see, I’ll ask here; is there/will there be an upgrad possibility to Avast! Internet Security for users who have the Pro Family Pack (1o Pro licenses)?
    And will there be a new version of the WHS version (the current was not able to recognise the beta).

    I don’t see the new Website neither. Where is it? Just asking.

    Hi all,
    Many thanks for the new free Avast antivirus!!
    Very exciting and much looked forward to, although v4 was great anyway… :o)
    Small question: I really like the old blue notification icon and can’t stand the new orange one. Didn’t try the Beta much ‘cos the orange icon was ‘noying!
    I have easily downloaded one of the blue icons. How can I use it and replace the horrid orange and go back to cool blue?!
    I see that I’m not the only one to think in this way, but sorry about such a mini-trivial question. And big apologies if it’s the new Corporate colour!
    Won’t stop me using Avast! stuff!?!
    All the best,

  19. January 19th, 2010 at 20:07 | #19

    The new website looks great! I like how you cleaned it up and clearly explain the difference between the product versions.

    When I uninstalled avast 4.8 with the removal tool and installed the new Avast 5.0, I see that the virus chest is missing, is it integrated?

    Thank you so much… I love the new version… You guys have indeed gone a very long way in terms of developing Avast. In fact, Avast 5.0 is a big leap from 4.8. I love it… Great job Alwil. :)

    If yes then you can download the pro version in multilanguage

    January 19th, 2010 at 22:51 | #36

    How do you mean?

    Boot scan is being worked on, for a later version. IIRC some defferences between the two versions mean some extra programming…

    Its very surprising to find such an effective anti virus absolutely free. Thanks a lot!

  38. January 19th, 2010 at 23:17 | #38

    Wow! The UI is beautiful, and no reboot required after installation is super!

  39. January 19th, 2010 at 23:45 | #39


  40. Thanks for information…
    January 19th, 2010 at 23:55 | #40
