Typically Avast is pushing the online installer (avast_free_antivirus_setup_online.exe) which is really small (about 5 MB) but requires an Internet connection to complete the installation as the biggest part is downloaded during the installation process. Sometimes you need to get Avast on a computer without the Internet connection and that’s why you need to download the offline installer (avast_free_antivirus_setup_offline.exe) in full size which takes almost 300 MB.

Avast offers standalone installers for all their product from antivirus family (Free Antivirus, Pro Antivirus, Internet Security, Premier) to Cleanup or SecureLine.

Offline installer contains the exact version of Avast as an online installer but you can transfer it to a USB disk and install basically anywhere. Even though the computer doesn’t have an Internet access it could get infected (for example when you transferring data from USB sticks, CDs or DVDs) and that’s why you need Avast Antivirus protection. All Avast offline products are fully compatible with Windows 10, 8, 8.1, 7, Vista and XP (32-bit or 64-bit).

My name is Paul and I love Avast since the Home Edition v4.8 (2008). I am recommending it to all my friends, but I realized they don't know how to use it. So I started this site in order to help others getting maximum from this awesome antivirus. Feel free to contact me via Facebook, comments below or this form.

    I have multiple computers with a metered internet connect. We need to update the virus definitions once and then push them to each computer. Do you need to download the full package (270MB) for each update?

      No. You only need a pen drive to transfer the Standalone installer between computers
