DEREKCURRIE  At this point in time it is important to note that ClamXav is over a year behind in its definitions of Mac malware. It is able to detect and remove Trojan OSX.RSPlug.A, discovered in September 2007. However, malware definitions for more recent Trojans are not built in. Specifically, there are no definitions for Trojan OSX.RSPlug variants B through E, Trojan OSX.Lamzev.A or OSX.Trojan.PokerStealer. Therefore, I consider it practically pointless to use it to detect and remove Mac OS X specific malware.

I am attempting to find a source for the missing definitions in order to have them provided to the Clamav developers. Wish me luck.

Meanwhile, as usual, ClamXav is a very good free anti-malware program for detecting and removing Windows specific malware.

An alternative FREEWARE anti-malware program for Mac OS X is iAntiVirus from PC Tools. It ONLY runs on 10.5 Leopard, but is entirely up-to-date.

Of the commercial anti-malware programs for general use, I only recommend Intego VirusBarrier, despite its cost. For business/enterprise users I recommend Sophos Anti-Virus.

I attempt to discuss current Macintosh security concerns at my blog:

(Version 1.1.1e942)

TRANCE  must uncheck both the checkboxes in the logfiles for it to work or you get errors like:

"Problems with internal logger

Can't open Library?logs/clamXav-scan.log in append mode (check permissions!)"

Scan Ended Unexpectedly. Error num: 62"

It also crashes one out of every two times you start a scan  
(Version 2.0.1)

KOBALT  Excellent, Mark! Thanks for this ever improving app - we may think we're pretty safe on our MacOSX platform, but it's only a matter of time ...  
(Version 2.0e95.2)

JRWHO  Tried looking on the web for the dev's contact info, couldn't find it. So I went on to the forums to try to contact him, and the forum never sent me a conformation email. Seems hard to contact the dev so I thought I'd try to get his attention from MU. I have a couple of requests for the app…  
(Version 1.1.1e942)

JCRAIG  Update includes version 0.94.2 of the scanning engine. Installed without a hitch. Excellent program from a developer who deserves your financial support. No amount is too small, Mark does a great job keeping this "free" program up-to-date; all that hard work has to be worth something.  
(Version 1.1.1e942)

XPLICIT  Quite an interesting approach to label a beta release with a normal version number.  
(Version 2.0.3)

GBBOB  This is a great program and of corse you cannot beat the price. BUT, it is a CPU HOG. When Clam Sentry is running in the background, it eats anywhere from 60 to 85% of the CPU and I am running a 2 gig G5 Tower with 3 gigs of RAM. It even causes my Mac to momentary freeze when i am in zoom mode and I hate turning it off because it has found malware and other software on my Mac that i did not download. The program does work well but it is just too much of a CPU pig. I went to Activity Monitor and it was at the top of the list eating 60 to 85% of the CPU load. I know the app is free and is even used in LCC and SLCC but there has to be a way to reduce the CPU demand. Please fix this major flaw in what could be a great virus software. End of Line...  
(Version 2.0.2b)

STRYCH9  Same for me on 10.5.8 G4 PPC Dual 1.25, works or crashes for the same file, try several times until an update...  
(Version 2.0.1)

YOUNKINT  2.0.1 crashing every time. Removed engine and ALL related ClamXav files, including cache files and prefs. Reinstalled everything. No dice. Still crashing every app start. 10.5.8 PPC QuickSilver and 10.5.8 PPC PowerBook. Both well maintained.  
(Version 2.0.1)

ZANGIEF  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.)
