ClamWin Free Antivirus Download FAQ

What is the ClamWin Free Antivirus offline installer?
The ClamWin Free Antivirus offline installer is a full standalone setup file — sometimes called a standalone installer or full setup package — that installs the software completely without an internet connection. Once you have downloaded the setup file, you can run it on any compatible machine, including air-gapped PCs, school labs, and enterprise workstations, without needing to re-download files during installation.
How is the ClamWin Free Antivirus offline installer different from the web installer?
A web installer (also called an online installer or stub installer) downloads the actual program files from the internet during installation, so it fails if your connection drops. The ClamWin Free Antivirus standalone offline installer bundles the full setup inside a single executable — you download it once, save it to a USB drive or network share, and install it anywhere, even without internet access.
Can I use the ClamWin Free Antivirus offline setup on multiple computers?
Yes — that is one of the main advantages of a standalone full setup file. Copy the installer to a USB drive or shared network folder and run it on as many machines as needed without an internet connection. Check the license terms from ClamWin for any per-seat restrictions before deploying to multiple workstations.
