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

avast! 5 is coming… soon!

After a long time of keeping everything in secret, I’m glad that I can now disclose some preliminary information about the upcoming avast! version 5. The first thing to note is that the product is coming relatively soon. Namely, we’re currently planning to release it this October.

The product will be offered in three flavors: a free AV (that will supersede avast! 4.8 Home Edition), a paid AV (successor of avast! Professional Edition) and a full Internet Security suite. As usual, all customers (or users) with a valid avast! subscription will get a free upgrade to this new version.

The free AV will, of course, contain all the features from the existing Home Edition, plus a couple of new extras (I’ll be sharing more details on the blog as time goes by). The paid AV now includes a new virtualization module as well as all the features from the free AV and features previously exclusive to avast! 4.8 Pro. And finally, the suite adds an antispam and firewall module and will thus provide you with a complete, worry-free protection.

All three products will share the same antivirus engine (e.g. all of them will still have exactly same detection rates) that has been substantially improved and optimized. It may sound like a cliché, but it’s a fact: the new engine can detect more viruses, while actually consuming less resources.

The performance optimizations were not confined to the AV engine only; the program now uses various tricks to feel as light as possible and to not interfere with your work in any way. For example, we have radically improved the time it takes the computer to boot, making the slowdown imposed by avast! almost unnoticeable. I’ll be very interested in getting some feedback from you on this one (as soon as you get a chance to test it – please read on).

Starting with version 5, avast! now officially supports heuristics (proactive detection), although between me and you, many of the stuff has already been present in the previous versions – but we haven’t marketed it in any way. Also, detection of Potentially Unwanted Programs (PUPs) has been added. Additionally, version 5 includes a new code emulator (or in fact, a dynamic translation module, to be technically correct) that will be of great help e.g. when unpacking malware samples packed/protected by unknown packers (as is the case pretty often).

All three products also feature a new user interface which has been completely redesigned for this new version. We’re abandoning the dual (simple vs. enhanced) UI model and replacing it with a single comfortable console, designed for both novice and experienced users. I’m attaching a couple of screenshots to give you an idea of what the product actually looks like.

The beta testing of avast! 5 will start in a couple of weeks (roughly by the end of July / beginning of August), so if you are interested to give it a try, please check back soon as I’ll be posting the details here on the blog as well as on our forums.

    I currently use Avast! PRO, i have no problems at all with it. I am a pretty advance user, atleast enough to know whats rogue and not. i am really looking forward to avast 5.0 and its firewall! I might not do beta testing though. but when it comes out in October i am gonna download right away, no doubt! i am currently beta testing iobit security 360(beta 2.2,Antimalware). it works really great with avast so any other users of Avast i recommend it with Avast(of course). IObit security uses normal protection, and DOG detection(Digital Original Gene) so avast and that make a great combo! Please check out iobit security at

    It is a great news for all the avast users all over the globe either the free one or the paid one. Avast has become one of the essential household anti-virus solution all over the world. The most important thing is that it supplies the free one without any problem of trial key or any disturbing pop-up boxes for upgrade. With version 5 there is a new sleek design user interface that is as beautiful as of any paid anti-virus solution with some of the new additional features like the in-built firewall and an anti-spam engine. With all these new capabilities i am sure that the customers of Avast will doubles in coming years. We will also see that it will touch the 80 billion mark in few years with the boost of version 5. In my view what i have found after using avast is that every thing is fine in it’s place in Avast except the user interface which i say the most ugly user interface any free or paid anti-virus program gives. In Avira and AVG free version is quite beautiful. But now i think after this most beautiful user interface Avast is getting in near future will make it the most used product in case of downloads or registration. It will create a new beginning in the history of anti-virus industry and quickly become the market leader in the field of inbound and outbound cyber security solutions. I am sorry for calling the user-interface of presant edition ugly but i think you will understand me sir. Avast is not only your product but a user-friendly product of millions. What i have said is a feedback from an Avast user. So don’t take it in any other way.

    There has always been native x64 support.
    Quoted from the avast! pro information page:
    Support for 64-bit Windows

    avast! Home/Professional now fully supports the 64-bit Windows platform. ALWIL Software is anticipating massive growth of this platform, as Windows XP 64-Bit Edition will support up to 32 GB of RAM and 16 TB of virtual memory, enabling applications to run faster when working with large data sets. Applications can preload substantially more data into virtual memory, allowing rapid access by the 64-bit extensions of the processor. This reduces the time for loading data into virtual memory or seeking, reading, and writing to data storage devices, making applications run faster and more efficiently.

    Regular (32-bit) antivirus applications are unable to operate correctly on the 64-bit Windows platform, because they rely on 32-bit kernel-mode drivers. The latest version of avast! uses native 64-bit drivers, delivering the same level of protection as the 32-bit Windows environments. The installation package is the same for 32-bit and 64-bit versions – the setup program automatically detects the operating system it is running on and installs all necessary files. You may find more information on avast! Antivirus and Windows x64 Edition page.

    Having been a Avast free Home user for some time I am more than satisfied with its performance. It has proved itself for my needs over Norton & I have recommended it to contacts in Brasil & China. A contact in China is currently using the Home edition with entire satisfaction.
    I am looking forward to the new Avast 5 to see what additional features it will give me. Looke like a cuestiion of the best being better. Three cheers for that

    I’m excited for the avast!5 release! i’m really impressed with avast’s performance in my computer, and i’ve been using it for quite some time. i think the version 5 will have a better look/interface and can block more viruses than ever…

    avast is really the best AV software!!! Congratz!!!

    I seriously hope the Home Edition of Version 5 won’t have the Firewall and Anti-Spam tabs and when you click on them it’ll be like “OMG PAY RIGHT NOW” or something. That only will make me replace Avast with Microsoft Security Essentials.

    I am just bitting my nails with nervousness waiting for August – just a few days now. I hope we will be autamatically ubdated for full version of Avast 5 after we finish bete accessment. I had a problem with an antivirus sight bug that Avast 4 did not block. It inserted a message in Windows search pages saying the web sites had viruses & to buy there AV. Microsoft was aware of this site but haver not blocked it.

    By the way the site to block which inserts a contaminated site message is http://suspicious – domain – in an effort to force buying their AV. Can U block it. It took me a day to removeit

    Avast will receive more stars when reviews are made

    Hi, I have always in my reviews given Avast five stars (out of five possible) and so does also many Avast users who writes reviews at different download sites. Avast users usually loves Avast more than other users loves their brands of antivirus software.

    Technical journalists who writes reviews does not generally to the same extent, I believe, give Avast quite as many stars as it users does (generally, maybe three stars or four stars out of five). Not that they are more correct in their judgement than its users are, actually I believe in the opposite as I myself, as I wrote, gives it five stars.

    Now with this new interface and heuristics capabilities implemented (heuristics already unofficially implemented in version 4.8) technical journalists will give it better marks or grades. This because heuristics will by time (which has already begun happening) increase Avasts detection capabilities even more and technical journalists are also very aware of this feature named heuristics. Many journalists also think that Avast layout is a bit awkward (I love, though, the radio player), but now all this will change and Avast will generally get as many stars as Nod32, Kaspersky, Bitdefender etc that is four or five stars out of five possible. Journalists will not have any other choice.

    I want to add that my points are only made regarding Avast Home Edition and Avast Professional Edition and not the new Security Centre as its reviews depends on how well it will function. Avast Home Edition and Professional Edition are already by its users, I suppose, tested as a lot of the features are already implemented.

    Less than one month ago I extended for one year the licence for Avast Pro 4.8.
    Very bad decision! I experience every day failures of your software (i.e. not working with the stop signal on the icon..), that requires to go “repairing” it.
    Moreover, few minutes ago at the end of a scanning, I read in some rows of the final report this funny diagnosis in italian ..questo file è una bomba a decompressione..! that is..this file is a decompression bomb!!! I can appreciate jokes in the proper places, but I hope you undestand that I must ask you a recovery action or the full licence refund. Thanks a lot for a ready reply.

    I didn’t mean to offend anybody with my opinion… I just feel that this new 5.0 appears rather complicated. I am sort of stuck with 5.0 because I paid for 2 years of Professional 8.4! If it at least supports skins like black vibe by szcraftec from Sasha Zivanovic-Craftec, then I’ll be alright. But this new one is somewhat revolting… What happened to the cool blue spinning “a” amd “i” as well as a cool design? Design always plays an important factor to casual users. If it doesn’t look attractive… I will go for the competitor. To me all anti-virus are equal… It really comes down to the look. Thus, explains why I am STILL using NetScape. The prettiest darn browser ever! I am looking forward to avast 5.0 if it supports more choices and better features and cool design for the screen! Thank you and smile!

    This is not a comment but a comply. I renewed the licence for Avast 4.8 Pro few weeks ago. When I power up the PC Avast is stopped and I have to go repairin or updating it. Moreover yesterday the report after a virus scanning was amazing:…in italian I read “il file è una bomba decompressa..!” that is “file is a decompressed bomb…! That’it really! In the past I appreciated your software but now I’m here to ask you a repairing action. Thank you a lot
