ClamXav 2.6.1 with ClamAV 0.98 backend - 7th October 2013
Requires at least Mac OS X 10.6 *
Available in English, Czech, Danish, French, German, Japanese, Korean and Spanish.
If you already have ClamXav 2.x installed, please use the "Check for ClamXav updates" option in the ClamXav menu as it simplifies the update procedure.
*If you're on OS X 10.4 or 10.5, please see below.
A slightly modified version of ClamXav is available in the Mac App Store.
What are the differences between the version of ClamXav available to download here and the version on the Mac App Store?
- The App Store version doesn't contain ClamXav Sentry, so it is not able to watch your computer for new files and scan them as they arrive.
- There is no engine installation phase as the App Store requirements stipulate that everything must be self-contained within the app.
- Virus definition updates are downloaded on a per-user basis.
- Updates to the ClamXav app itself are taken care of via the Mac App Store.
- Mac OS X 10.6 or greater is required.
The exact same version which is on the Mac App Store can also be downloaded here.
Note: The AppStore version is still at v2.3.6 as v2.6.1 is a substantial rewrite and requires a lot of work to bring the AppStore version up-to-speed. It will happen soon.
New versions of ClamXav have a minimum requirement of OS X 10.6, so if you're still using something older than 10.6, please select the correct version below:
For Mac OS X 10.5, download Version 2.5.1
For Mac OS X 10.4, download Version 2.2.1
You should keep checking for virus definitions as you will still receive updates for these for the time being.
The SHA1 checksum can be used to check the authenticity of files you download from this website. To use it, open the Terminal (which is inside the Utilities folder), type
followed by a space and then drag into the terminal window the file you downloaded, hit return and verify that the number returned to you is the same as the one here.
Note, this will not work if you decompress the archive first. You have to do it on the exact file you download from this website.
sha1 for ClamXav_2.6.1.dmg is 96f87257b466b2ac1eb6f5b9e32b83ca92664788
