Official download site and source

[Lukas_25]

Hello,
what is official site for downloading avast free antivirus? When I searched "avast" in Chrome browser and google page, I get two different links.

1. link)
https://www.avast.com/cs-cz/lp-ppc-hp?ppc=a3&gclid=EAIaIQobChMI_4irgbOT4AIV1TLTCh0eLQtPEAAYASAAEgICXvD_BwE&gclsrc=aw.ds
When I click to download, I´m redirect to https://www.avast.com/cs-cz/download-thank-you.php?product=FAV-PPC&locale=cs-cz&ppc=a3

after automatic download I get "avast_free_antivirus_setup_online_a3a.exe" (7,1MB) from https://install.avcdn.net/iavs9x/

2. link)
https://www.avast.com/cs-cz/index#pc
When I click to download, I´m redirect to https://www.avast.com/cs-cz/download-thank-you.php?product=FAV-ONLINE&locale=cs-cz

after automatic download I get "avast_free_antivirus_setup_online.exe" (0,2MB) from https://bits.avcdn.net/productfamily_ANTIVIRUS/insttype_FREE/platform_WIN/installertype_ONLINE/build_RELEASE

I donť understand what is difference between these files. Thank you

I think that both files are ONLINE installler.

Pondus provided the main link to installers above:

Online installer = 6.0 MB
Offline installer = 334 MB (Avast Free)
Avast clear exe = https://www.avast.com/uninstall-utility

Antivirus vendor uninstallers:  https://support.avast.com/en-ww/article/11/#artTitle

the smaller one 0.2MB is the latest one online installer, better handles different OS and OS architecture. at the end both of them will do the same, install Avast Free Antivirus, the difference might be just in the amount of data downloaded during installation.
