Is ClamWin Free Antivirus safe to download?
The installer comes from a recognised distribution platform rather than alch's own domain. That is normal for this kind of software and not a red flag by itself.
The installer on this page comes with the SHA-256 alch declared, so you do not have to take our word for it: hash the file you downloaded and compare.
What this does not tell you is whether the software itself is any good, or whether you want what it does once installed. A publisher can ship something you would rather not run and the download is still authentic. We answer the question we can measure and leave the other one to you.
If Windows says “Windows protected your PC” when you run it, that is SmartScreen reporting reputation, not a malware verdict — it shows up on perfectly legitimate software from small publishers and on releases that are simply new. The reverse matters more: no warning does not mean the file was checked.

Install ClamWin Free Antivirus with winget
Windows ships with a package manager, and this program is in it. The identifier below is the one Microsoft's repository uses, which is also where the download URL and hash on this page come from.
Install
winget install --id ClamWin.ClamWin --exactUpgrade later
winget upgrade --id ClamWin.ClamWinWhy --exact: without it winget matches on name as well as identifier, and a search that returns more than one package makes it stop and ask rather than install. Pinning the identifier is what makes the command safe to put in a script.
Not installing anything, or getting an error back? The commands that actually come up covers upgrading everything at once, what --include-unknown is for, and why winget can be missing from a machine that should have it.
Old versions of ClamWin Free Antivirus1 with hashes
The version history of ClamWin Free Antivirus, each release with the download URL the publisher declared at the time and the SHA-256 to check it against. Useful when an update breaks something and you need to downgrade to a build that worked.
We do not host any of these files and never re-upload them, which is the difference between this and an old-version download site.

Publishers take old builds offline without warning, so a link here can stop working even though the hash stays correct forever. If you already have the file, the hash is what matters: it tells you whether what you have is what they published.
