ClamXav is a free virus checker for Mac OS X. It uses the tried, tested and very popular ClamAV open source antivirus engine as a back end.
I hope you like and use ClamXav a lot and that it helps keep you and your friends/colleagues virus-free. Although I'm providing ClamXav for free, I am increasingly spending more and more time developing it and would really appreciate if you would consider making a donation please. All donations (no matter how small) are gratefully received and would be a huge incentive to help me work on future versions of ClamXav, but more importantly
What's New
Version 2.2.2:
Updated ClamAV engine to 0.97.2
Fixed an issue where virus definition files may end up with wrong permissions after an update
Fixed window placement bug on Mac OS X 10.7
Fixed Spanish translation error in the scheduling preference pane
Updated engine remover for LaunchAgents
Mac OS X 10.4 users should NOT download this update
I've never had any problems with any version of the app on any version of OS X (Only been using since Tiger, so I still consider myself a n00b!). It has caught nothing on he machine _I've_ had since then, but it has on machines owned by my wife, and some of my friends.
Love the interface, and doesn't unduly slow down my April 2008 MacbookPro.
Had to give it 5's! It found Worms in eMails I trashed cause they did not look like anything I should get. I told a friend about ClamXav and they found a Trojan in there computer that was from Facebook!! Well. It is free and does a great job. Make sure to always update Definitions before each use.
ClamXav is nice because it's "free," but it certainly doesn't run on Mac OS X free of problems. This was the first antivirus I tried on my Mac w/ Lion, which was based on suggestions by others. However, I ran into all sorts of problems when running scans.
The first thing I noticed is that running a scan renders my computer useless. ClamXav slowed my computer way down, and that's saying a lot because my MacBook Pro is new. Frustrating, to say the least.
Secondly, I decided to add some exclusions to see if that helped ease the lag caused by this software. After running a few more scans, I found that ClamAV is ignoring all exclusions that I have put into the exclusion list.
For example:
.jpg
.jpg$ (as a regex)
These exclusions are "enabled," but I dont understand why then it still scans every singe .JPG file on my computer. Is this a bug? I'm not sure. But I do know its very annoying.
Thirdly, I found ClamXav's user interface to be confusing and more of a hassle to deal with than what I initially expected. I'm sorry to say it, but this software is bad. So I uninstalled.
I decided to download ClamXav after getting frustrated with Sophos. I'm scanning my entire HD right now--130 GB--and it's halfway done after only twenty minutes or so. It's pretty bare-bones, but there's no need to have bells and whistles on something like an AV. Overall, a good download:)
For peace of mind ClamXav is a must have. Runs in background with no problems on Lion. Easy to set up watched folders and virus definitions are updated daily. Scanning engine is also being continually improved by Dev. Just get it.
Works perfectly fine for me under OS X 10.7.1 Lion. Not sure what issues others are having. Perhaps boot into the Lion Recovery partition and perform a permissions repair in Disk Utility... then try again.
I actually like the interface as well as the database that calmvax has, it actually found some infected files which other programs didn't !!
But the only thing is that i noticed were, it use a huge amount of CPU usage and my macbook pro start gets hot and the fans gets spinning faster in order to balance the temperature.
ClamXav STILL DOES NOT WORK IN LION! I have uninstalled and reinstalled v. 2.2.1 twice, but it still gets stuck in the loop of demanding that I download the latest virus definitions, but it already has them, so it insists that I quit. It just won't run.
Here's the Alert text: "Please download the latest virus definitions before continuing." This is presented with 2 buttons: Quit & Update Now, each of which leads you back to the other in an unending loop.
@Robertcoogan
"Probably best to wait for an update.
The world won't end in the meantime."
How can ya be sure that the world won't end?
Fukushima nuclear radiation poisoning the world,
Wars in the middle and near east,
World's financial/economic systems coming apart.
Civil unrest in more and more countries,
Human nastiness everywhere,
and ad infinitum.
Maybe it's time for the world to come to an end, hmmm?
That would be poetic justice, I'd say!
I used this nice soft a long time, but it started not working for me anymore for some months.
When start this app (ClamXav 2.0.7) the window will appear: "Alert. Please download the latest virus definitions before continuing." When I press "Update Now.", the app will tell that "Definitions already up-to-date", and all starts all over again with "Alert. Please download the latest virus definitions before continuing". So endless loop...
The similar (not to say exactly the same) problem started with previous version where choosing "Update Definitions" gave "Starting update… Update Finished", but actually the database wasn't updated, and a reason "sudo: no tty present and no askpass program specified" was displayed.
i can't find anything to explain why when i scan my hard drive it quits unexpectedly with options on screen to relaunch etc, i have looked through developers site and forum and can't find some sort of explanation....has any one else had this problem i can't work out why it has suddenly started to do this ONLY to scans involving my HD everything else works fine...
Have had and loved ClamX for years. Donated several times. Recently (finally) updated to Snow Leopard from 10.4.11. Updated to ClamX 2.0.6. For whatever reason cannot complete virus definition updates. Starts then stops, then I get an 'error 54' code. Then a request to try again (ad infinitum) Have uninstalled and re-installed both the program and engine several times, along with posting on the ClamX forum, but so far no luck. Also no luck tracking down what the error codes mean. Wondering if anyone here has any ideas how to get this unstuck?
The URL of the ClamX Forum - as noted above - is :http://markallan.co.uk/BB/viewforum.php?f=1
BTW - my problem is resolved. It appears it was a firewall problem in the hotel I was staying at and working out of. When I returned home, all worked fine.
This is really a good anti-virus app on mac and the most important to me is that it's totally free :P
However,i've got the problem that it'll scan my removable disks automatically even though i have the option ''scan inserted disks'' unchecked,this adds about 60% cpu usage,so it just becomes kinda hot there...
Anyone here could help me out,hopefully?thanks you guys
ClamXav 2.0.6 crashes when invoking the settings menu while antivirus signatures (.cvd) are updating. Sending crash report to Apple OKed...
This behaviour is reproducible.
First time ever installation of ClamXav, Mac OS X 10.6.3, all updates.
You have to go to ClamXav in your menu bar and open ClamXav's drop-down menu, then click on 'Launch ClamXav Sentry'; its icon will then appear in your menu bar.
Have you tried updating the definitions in ClamXAV before starting it? It was giving me an error that it couldn't find the ClamAV engine until after I did that.
Error 52?
I've been using ClamXav for quite a while now, without difficulty. I am running OS 10.5.8. on an intel core duo iMac.
After upgrading to 2.0.5 I am unable to "update virus definitions."
I get this:

I've tried uninstalling and going back to the older version.... no change....anyone help?
I also went to the clamX site, but didn't get any ideas from there.
Thanks;

OK, all's well.
I did the uninstall that comes with the package and that uninstalled the engine. After a re-install (with a new engine) all works as it should.
I do have to say that I love this app and kudos to the developer.
I have a PC for work and the virus detection on that one is just so boring.
Clam stuff like this is just such a hoot.... "I will quarantine infected files
..." Shades of "Hal." LOL!
I had been using an older version of ClamXav (2.01) and noted it was no longer starting up (it looked like it but was not). I downloaded the newest version 2.03 215.
Now it won't scan and gives me an error message "immediately" to a folder that no longer exists relating to where viruses had been kept with 2.01.
The Message is: ERROR: '"/Volumes/OneTouch4/Virus for ClamXav/"' doesn't exist or is not a directory
I had the same problem after doing the same upgrade as you.
Solution (lucky guess, worked for me): unistall the program completely - I used AppCleaner for that. Re-install and it should work.
My guess, there's some incompatibility in the old plist.
I haven't experienced this issue, but I wanted to point out that if the problem is with a preference file, you can just delete it without uninstalling the rest of the application. The plist file will be automatically recreated the next time you launch the application.
The UI in the screenshot looks nice. Too bad I can't get past the "No warranty" dialog. Click OK, the app hangs for a couple seconds and crashes. Mac OS X 10.5.8, running on an iBook G4 (because I'm cheap like that, or maybe I just don't want to spend money on a new laptop. Whatever.)

If the way that you try to start Sentry is additional to (or different from) the method that's offered within ClamXav, then you may expect a problem.
