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

avast! – The most downloaded free antivirus in 2010

To provide free antivirus security means making the product available for people to download.  Obviously, the number of downloads is then a good indication of how popular the product is (well, it needs to be taken with grain of salt… there is more to it than just one number … but it’s a good indication, nonetheless ;-))

First, we got a note from CNet a week or so ago that avast! was the 2nd most-downloaded antivirus on in 2010 (behind AVG).  Moreover, avast! has the highest editors’ and users’ ranking, which naturally put smiles on our faces. is the single biggest downloading site in the world, so to be second there is a great achievement. (BTW, all the best to AVG for the top spot and we hope we will switch places with them this year ;-))

Yesterday, a story from PC World popped-up via the alert notification… advising users “…looking for high-quality free software…“ to check out the “…best-reviewed and most-popular program…”. Yes, avast! Free Antivirus is their TOP choice and download for 2010.  Thank you, PC World!

Btw, both articles are here:,1660-order,4/files.html

That got me thinking:  how did we do overall in 2010? is the biggest and PC World is certainly influential, but there are more downloading sites out there.  Aside from, we monitor and have the stats for:,,, in France, in Italy, in Germany, in Poland, in Russia, and in Brazil, and several others in smaller countries.

In total, we did really well in 2010! Combining all downloads from the sites we measure,  avast! is the MOST downloaded free antivirus with a total of 141,320,488 downloads.   AVG came second with 132 million, followed by 105 million downloads of Avira.

Not a bad year ;-)

    There may not be partying in Brno and Prague (and the UK for that matter), when they see those numbers. Of course, in the end, it is the installed base that’s important. Free SW has no switching costs and is disposable pz so it’s what is on the pc and/or laptop at the end of the day that’s important. Even more important to the shareholders, what’s the cash flow? Are those free people generating revenue? Are they converting to a paid product. Craig Kensek

    seriously, the most downloaded? I always thought that what matters are the registered versions of your programme, that means, that users are actually “using” the software, not just they download, try and uninstall…

    @john dear
    Indeed. We do track the number of registered avast! users and the number of users who use the product. I will write a full post on that. But of course we don’t have the same info for the other brands. So, everthing else being equal the downloads are a good indication.

    Avast ask me to download the latest Avast free antivirus, what i deed. One week ago.
    But my Notebook Inspiron 8200, Intel P3 500 KB memory, Windows XP got unuseful.
    None other software could run.
    You should warn what is the minimum configuration required.
    The only solution was to uninstall Avast antivirus latest version,

    @Ricardo F.
    Ricardo, the minimum system requirements are listed on our website ( ) and should be well sufficient for your needs – assuming – you indeed have Intel p3 with 500 MB RAM not 500 KB.
