IGREG I have to say that my review may have been hasty, it seems to use a lot of CPU at certain times. I am looking into it (Version 1.3.5) | |

VICJOE The lengthy list of viruses/malware on the developer's page is misleading; there are a number of old viruses for OS 9 and the Classic environment, yet this software only works on Intel machines with Leopard, which of course cannot run the Classic environment. (Version 1.3.5) | |

IGREG Have had it installed for several hours now. I have noticed no problems. Uses about 40 MB of RAM for application and a background program. Quick scan was pretty quick. Even the full scan was not too bad, about 45 min for hard drive with about 55 GB of data. No noticeable system impact. Interface is user friendly. It is free for home users. I switched from Intego Virusbarrier, which uses more than twice the RAM and has a weird and confusing interface with the current version. Plus its annual subscription renewal is expensive. (Version 1.3.5) | |

SURFSPIRIT BAD! OK, it was lot faster than ClamXav to scan files, but din't found any of the two virus ClamXav had made alert, I also run Kaspersky via Parallels to the same usb pen, and Kaspersky confirmed the two virus. All the antivirus used their most recente database. ClamXav seems better, you can even easy scan any file or folder by mouse click menus. I also run Sophos aclamed anti virus and the result was the same as iAntiVirus, a shame! Above of all this, I am completely sure my pen was infected because it was used to try to desinfect a friends pc that was full of virus and malware. So if you want an anti Virus for mac so you minimize your friends pcs nightmares, choose ClamXav! (Version 1.3.5) | |

FAHLMAN Because iAntiVirus only scans for Mac viruses it will not find Windows viruses. (Version 1.3.5) | |

SURFSPIRIT Well, then this software is completely useless! Just say at loud the new virus for mac, humm, well, can't remember any, and don't tell me that a program that asks your admin password is a virus! (Version 1.3.5) | |

KOSOVAR1 Apparently the iAntiVirus developer's pricing policy has changed. I used to use a free version of iAntiVirus and it was happy to the download updated virus definitions files. Today, I tried to dp this and the program no longer allows updating unless you install the commercial version. It made me feel GREAT to be able to simply delete iAntiVirus and switch back to the excellent ClamXav antivirus alternative. That program works beautifully, except for being rather slow. I simply set it to scan the 250 gigs of data on my laptop overnight while I sleep. Since functioning viruses, trojans, etc. are EXTREMELY rare on Macs, I really don't worry much about real-time updating and certainly wouldn't waste money on a solution I have to pay-for. I realize now that I only switched to iAntiVirus because the interface was more Mac-like. If ClamXav were given a little facelift, more people would probably choose it or stick to it since it IS the superior product. And, did I mention it is FREE? (Version 1.3.4) | |

PIRX On cleaning my HD I just found 260 MB of ClamAV logs in /Library/Logs! After testing around with everything & sundry, I am back at Intego. (Version 1.3.4) | |

PIRX Well, I had ClamAV running all the while on Tiger, folder sentry on my PowerMail e-mail attachments folder, documents folder and downloads folder. Then, upon finally upgrading to Leopard last week (October 2008), ClamAV instantly warned me about 3 Windows virii, 2 of them in my e-mail attachment folder, one from 2005 and the other one from June 2008, as well as one in the download folder. For some reason I was mighty unimpressed by ClamAVs performance, but it is hard to blame ClamAV, as Intego VirusBarrier and Sophos had also failed in detecting the virii! If there should be an aggressive new virus out there, I reckon that the chance of either aforementioned software on a Mac catching it may be no better than 50/50. Apart from corporate compliance, the point of having AV software running on a Mac is the same as using a condom in real life: To protect yourself against against an unlimited variety of known and unknown infections. If iAntivirus can reliably do that better than the others, then it is a sure winner. (Version 1.1) | |

SULIS "If there should be an aggressive new virus out there, I reckon that the chance of either aforementioned software on a Mac catching it may be no better than 50/50." Actually it's zero. Anti-virus software can only detect a virus of which it's already aware. Any unknown virus is undetectable until the software is updated to recognise it. Since there are currently no known OS X viruses there is - as yet - no good reason to install Mac anti-virus software. (Version 1.2) | |

XENOPHILE A condom doesn't tell you if it "discovers" a virus while your being intimate with your partner, and it blocks all viruses, not just the one's it "knows" about. Also, ClamXav doesn't make using your Mac significantly less enjoyable. Maybe it would be best to leave condoms out of any antivirus software discussion. ;) Sounds like what happened is that when you updated to Leopard, ClamXav somehow updated its virus definitions. Did you reinstall ClamXav? Another possibility is that those viruses were coincidentally added to the definitions around the same time you updated to Leopard. In any event, you should never assume that any AV software removes 100% of viruses from your system. Always handle files based on the assumption that they may be infected. (Version 1.2) | |

SULIS iAntiVirus is nothing like a condom. It won't catch any Mac viruses, either the ones that don't exist or the ones that haven't yet been created. (Version 1.2) | |

EASER If it does act like a condom, will it reduce the pleasurable experience I have of using a Mac? Sorry, I couldn't resist. (Version 1.3) | |

PIRX To clarify my point: We are living in a Windows world. We work with files from Windows users and we forward files by e-mail. Photos, documents, spreadsheets, presentations. As a Mac user you will not notice that you are spreading a virus, unless you apply anti-virus software. And that is the condom function of using AV software on a Mac: You don't have unprotected interaction with the opposite sex. As to the likelihood of virii affecting Macs, I think is is not a question of "if" but only a question of "when". (Version 1.3.2) | |
 | Jan 16 2009 |
SULIS You really shouldn't be forwarding on files of which you know so little but if there's an unprotected Windows machine out there you can be fairly sure that it will already have been infected by a Windows collleague. It's not your job to cripple your own Mac in order to protect Windows users too stupid to have installed their own anti-virus software. (Version 1.3.2) | |
 | Jan 16 2009 |
PIRX "You really shouldn't be forwarding on files of which you know so little": And just how - without anti-virus - can you be sure that the file that you received from your business partner which you need to forward to your supplier does NOT contain virii or mad macros? What you state is like saying "I am immune to HIV, so if I carry it to others it is none of my business". Use condoms, honey, on every conceivable occasion. The statement of crippling your Mac with anti-virus is complete and utter nonsense, we do not need to discuss that further, or do we? (Version 1.3.2) | |
 | Jan 16 2009 |
EASER Well, so far this is proving to decrease the pleasure I get out of my Mac. (Version 1.3.2) | |

HIDDUKEL My post was removed by someone when I pointed out the obvious fact that macs don't need any sort of virus protection... just intelligent thinking. A valid comment, is it not? TRY to get a working virus on a mac. I'll bet you don't have any until you install a program that you paid for to remove them. (Version 1.1) | |

MUDFLAPPER There is some, although not much, malware out there for OSX. Chances are none of us will ever have to deal with viruses, which is wonderful, and one of the many reasons I've always loved Macs so much. However, as a graphic designer, some clients require me to run anti-virus software. And, since our Windows-using friends out there have tens of thousands of viruses to deal with, us Mac users can easily pass these viruses on to PCs, even though our computers are completely immune. (Version 1.2) | |

SHOTGUNWEDDINGS Great another Mac-wannabe-pc-looking POS. Completely useless software for real world use. I'll stick to ClamAV , thanks but no thanks. (Version 1.1) | |

CARLOS85 What kind of comment is this? Judge the software based on the merits of whether or not it does well what it is intended to do, not on your opinion of how useful its real-world application is. (Version 1.1) | |
 | Oct 9 2008 |
CALL ME YO DADDY I think it's your comment that is a POS. Try telling that to the Mac users who were infected by the DNS-Trojan that slowed down their Macs to a crawl. While they were few in number, it still happened. All you have to do is just google "Mac DNS trojan". But what it really sounds like, is that you're either a very miserable person or just having a bad day. Cheer up, you're a Mac user, you have plenty to be happy about. :) (Version 1.1) | |
 | Jan 16 2009 |
SHOTGUNWEDDINGS You missed the point completely. As a Mac user I don't want to see ugly PC looking GUI's That's why I'd rather stick to an alternative ClamAV. Bad day, what's that, never had in my life LOL (Version 1.3.2) | |

FAHLMAN ClamXav has possibly the ugliest UI of any Mac app that isn't X11- or Java-based. (Version 1.3.5) | |
