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

avast! Free Antivirus – yes, it’s that good

New Zealand’s state MetService website was hijacked by malware (apparently a fake antivirus) during a particularly high time for traffic, according to a news article. The article has prompted more than 100 comments in the first day, mostly from understandably upset site visitors who may have picked up the malware on their computers.

Here, however, I just want to show you one comment, as it’s nice to see this sort of feedback in the real world. It’s no secret that we typically offer our free version in tests against our competitors’ paid-for versions, but even the results from independent testing facilities don’t feel as rewarding as  feedback like this from our user community:

Fortunately for those MetService users who were not using avast!, they can install it now and run the avast! boot-time scan — and that should do the trick. ;)

    Woah proud to be an avast user for quite a long time.long live avast!!

  • Stavrius

    Dear avast developers. I use NOD32 Antivirus for my PC. If you are as good as you say you are, can you please ensure me that I’d have nothing to lose if switch it to Avast Free Antivirus? Thanks

  • Jason Mashak

    I’m not a developer here, but I’ll respond the best I am able.

    ESET (maker of NOD32) is a good company. They’re based a few hours east of us, in Bratislava (Slovakia). Strangely enough, AVG is between us, based in Brno (Czech Rep). All three of our companies, all based in the former Czechoslovakia, typically lead in independent antivirus tests.

    As an American who moved here to Prague in 2006, I can tell you that there’s something about the mentality of the region that makes our security solutions more effective than those of many other companies. You could say it’s an incredible sense of practicality – i.e., complex theoretical approaches are fine, but the real question is does it really work? Compare it to the mentality of the American Midwest, where so many immigrants from this region have settled during the past century.

    If you had written that you use one of the more popular security ‘bloatware’ products that often come pre-installed on people’s computers, it would be easier to answer your question with a clear ‘yes, you are correct – you have nothing to lose and much to gain’. ;)

  • Deeptam

    I shifted from NOD32 to avast….Avast is way too better than NOD32..I like its faster scan rate & boot-time scan..

  • freddie

    good ol’ avast! its served me well

  • Rahul

    love you avast! It’s been 3 or more happy years since i’ve been using it. :)

  • Dave

    I’ve been using Avast for years and have never had a virus. I’ve tried numerous other packages on other computers, but all have disappointed in one way or another (letting threats through, slow scans, eating system memory, conflicting with other programs, etc). Avast just seems to blow the competition out of the water! Everyone at Avast offer one heck of a pat on the back for their continuing excellent work!

  • Stavrius

    @Jason Mashak
    Jason, thanks for your respond.

    Well, I’m Greek so I know quite good the region of the former Czechoslovakia. It’s not far away from here. :)

    Anyway, I got your point. Thanks again for answering.

  • coolmario88cp

    Avast has protected my computer from many viruses. Avast Anti-Virus is AWESOME! :)

  • Reece

    Avast is a really good free antivirus program and you really got nothing to loose it saves alot of avast users from viruses and comes with voice effects which you dont see in virus programs alot.

  • Stavrius

    Hey Deeptam , as you already know, NOD32 is very light and fast antivirus software. This is actually my only concern about switching to Avast free. If it’s at least as fast and light as NOD32, then I guess I’d give it a try.

    Thank you Reece!

  • ilikeavast97

    i like avast!,it always secures my computer while being on internet.only had one major problem,but i fixed that myself.Avast! is a very good free anti-virus.. if teh free one is this good,what would the premium be :o

  • JC

    I tried many antiviruses but did not find better than Avast – and believe me, it is not only because I am Slovak….@Jason Mashak

  • http://N/A Don

    I tried the free version of Avast for a year and loved it so much I upgraded to the paid version and have been keeping up the subscription ever since.
    I’m a big fan of try before you buy and Avast proved itself right off the bat!
    I recommend it to everyone who asks me what anti-virus software they should get!

  • Pereira

    Avast is the best!!! i have used almost all other anti virus programme but nothing compares to avast…. talk of simplicity and performance…. i will rate avast 100 over 100…

    m using this in a smaLL CITY in India.. I used 2 buy paid softwares, bt no use.. keep it up 4 ever

  • Richard

    We have been using Avast now for many years, and love it, zero hassle, zero infections, and often use it to clean up our customers infected computers too. Its way better than AVG and NOD32 by miles…

    AVG has long cause a lot of other applications to stop working and NOD32 is just far too complex for average users to even figure out, and neither are as effective as avast! Avast rules…

  • yanita

    yes the great avast is true free fast antivirus

  • freeware-antivirus


    I have also used Avast Anti-virus, its really good protection.


  • shre54321

    i wanted to see lord ganesh pictures on the net yesterday and i used google for that clicked on the third link and avast! blocked the site and came up saying that it blocked JS-Redirector-DC….good job avast!

    I used many antivirus softwares and Last was Nod32. But Avast is better than all other antivirus softwares. I have been using avast for last 5 to 6 months. I find it realy good. I used 3 avast products. free antivirus, avast pro and internet security. These all are good and better than others.

  • LunarWolf

    Actually, I still think Kaspersky is better than avast. Here are my reasons :

    1. Kaspersky self defense is superior compare to avast’s. Look at the test done by Malware Research Group. Kaspersky have been consistenly scoring 100% in their test. Not sure is bias or not as Dr Web also score similarly high as Kaspersky. Both are Russian products.

    2. Kaspersky heuristics is better than avast’s. Look at AV comparatives Retrospective/Proactive Test. Not only that, Kaspersky performance in Whole Product Dynamic Test also speaks of the result itself.

    3. Kaspersky’s response time to the threats I submitted to them is faster than avast’s. Avast takes I think 3 days. Kaspersky in a matter of hours.

    4. Kaspersky have real time cloud analysis of unknown malicious file (2011 version onwards. Didn’t see it in earlier version). Say a computer which have Kaspersky install didn’t have the signature for a particular malware, but Kaspersky Virus Lab have identify it, the computer which have Kaspersky install will warn the user that Kaspersky Security Network (their cloud system) have mark the file as dangerous and the system is protected. That is the most impressive feature I have seen in Kaspersky. I admit, I was blown away.

    5. Kaspersky is a Russian company. Russian programers are known as one of the best in the world.

    Kaspersky have slip in the 2011 version where their detection rates drop and stuff like that but they bounce back with their 2012 version.

    But I am still a avast user. Why?

    1. avast prove itself that it is one of the best in its class. Not the best yet, but maybe in the future.
    2. avast is free.
    3. avast is catching up with Kaspersky. :D

    Any time you run more than one computer security program you take a risk, as each is specifically designed to do a job, but not necessarily specifically designed to be compatible. On the particular compatibility you’re asking about, the best source of info would be our avast! Forum members, many of whom help us a great deal in optimizing avast! features and functionality:

    Typically, any time a new browser version is released, many plug-ins that do not yet work with them are fixed within a few days and an update is sent automatically to users. If you are still having problems after a few days, check the avast! Forum or our Support page

    I like reading testimonials like this from repair techs, as they’re the ones who have “seen it all.”
