This comment applies to malicious software ('malware') that's installed unwittingly by the victim of a network attack. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the victim's computer. That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user, but internally Apple calls it 'XProtect.' The malware recognition database is automatically checked for updates once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
That statement may cause some Apple users to argue or walk away, but 2017 has so far seen more Mac malware and adware than ever before. In 2012, the Flashback Trojan infected 600,000 Macs.
The following caveats apply to XProtect. It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets (see below.). It only applies to software downloaded from the network. Software installed from a CD or other media is not checked. Starting with OS X 10.7.5, there has been another layer of built-in malware protection, designated 'Gatekeeper' by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't actually been tested by Apple (unless it comes from the Mac App Store), but you can be reasonably sure that it hasn't been modified by anyone other than the developer.
His identity is known to Apple, so he could be held legally responsible if he distributed malware. For most practical purposes, applications recognized by Gatekeeper as signed can be considered safe. Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following.
It can easily be disabled or overridden by the user. A malware attacker could get control of a code-signing certificate under false pretenses, or could find some other way to evade Apple's controls. For more information about Gatekeeper, see.
Beyond XProtect and Gatekeeper, there’s no benefit, in most cases, from any other automated protection against malware. The first and best line of defense is always your own intelligence. All known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called 'trojan horses,' which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and the malware attacker. If you're smarter than he thinks you are, you'll win. That means, in practice, that you never use software that comes from an untrustworthy source. How do you know whether a source is trustworthy?.
Any website that prompts you to install a “codec,” “plug-in,” 'player,' 'extractor,' or “certificate” that comes from that same site, or an unknown one, is untrustworthy. A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim.
(Some reputable websites did legitimately warn visitors who were infected with the 'DNSChanger' malware. That exception to this rule no longer applies.). Pirated copies or 'cracks' of commercial software, no matter where they come from, are unsafe. Software of any kind downloaded from a BitTorrent or from a Usenet binary newsgroup is unsafe. Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website.
If it comes from any other source, it's unsafe. Java on the Web ( not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was never a good idea, and Java's developers have had a lot of trouble implementing it without also creating a portal for malware to enter.
Past Java exploits are the closest thing there has ever been to a Windows-style 'virus' affecting OS X. Merely loading a page with malicious Java content could be harmful. Fortunately, Java on the Web is mostly extinct.
Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a specific task, enable Java only when needed for the task and disable it immediately when done. Close all other browser windows and tabs, and don't visit any other sites while Java is active. Never enable Java on a public web page that carries third-party advertising.
Use it only on well-known, password-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the address bar with the abbreviation 'https' when visiting a secure site. Follow these guidelines, and you’ll be practically as safe from malware as you can be. Never install any commercial 'anti-virus' or 'Internet security' products for the Mac, as they all do more harm than good, if they do any good at all. If you need to be able to detect Windows malware in your files, use the free software ClamXav — nothing else. Why shouldn't you use commercial 'anti-virus' products?.
Their design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere. In order to meet that nonexistent threat, the software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance. By modifying the operating system, the software itself may create weaknesses that could be exploited by malware attackers. ClamXav doesn't have these drawbacks. That doesn't mean it's entirely safe. It may report email messages that have 'phishing' links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them.
Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application. ClamXav is not needed, and should not be relied upon, for protection against OS X malware.
It's useful only for detecting Windows malware. Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else. A Windows malware attachment in email is usually easy to recognize.
The file name will often be targeted at people who aren't very bright; for example: ♥♥♥♥♥♥♥♥♥♥♥♥♥♥!!!!!!!H0TBABEZ4U!!!!!!!AVI♥♥♥♥♥♥♥♥♥♥♥♥♥♥.exe ClamXav may be able to tell you which particular virus or trojan it is, but do you care? In practice, there's seldom a reason to use ClamXav unless a network administrator requires you to run an anti-virus application. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services.
Disable any services you don't use in the Sharing preference pane. All are disabled by default.

The best anti-virus for Mac is Mac OS version 10.12.5 if you want to use a 3rd party anti-virus for here the findings on these forums is you would get better results re-enacting Robert DiNeros role as Al Capone when he beats up that guy with a baseball bat, with you as Capone, your computer as that guy and a sledge hammer as the baseball bat. Seriously they all screw up OS X and they don't work, you would better spend your money giving it to drug addicts and telling them they can only buy more drugs with it. It certainly isn't a virus. Maybe if you post an EtreCheck report, we might be able to offer some suggested solutions. I suggest you use the program created by Etresoft, a frequent contributor.
It will provide a snapshot of your system which we can analyze to possibly determine the cause of your problem. Please use copy and paste as screen shots can be hard to read. On the screen with Options, please open Options and check the bottom 2 boxes before running. Click “Share Report” button in the toolbar, select “Copy to Clipboard” and then paste into a reply.
This will show what is running on your computer. No personal information is shown. You have to be joking?! Virus and Adware don't exist in the Mac world? Why does Apple update for Security Problems if they don't exist? Why does Apple support AntiVirus and Adware protection on the App Store most of these apps are free. What is the financial incentive for creating and distributing them?
Why do these apps warn you of and block the download or remove these malicious items from your drive? Why is it that after these items are removed from your Mac that it suddenly works again like it is supposed to? Kathy this is a dangerous world for Macs and PCs.protect yourself! There are no viruses that can attack Mac.OS X.
So, anti-virus programs are selling a cure for a disease that doesn't exist. And they are renowned for borking Mac systems.

A Mac can pick up malware but not if you just use common sense. You really have to actively invite some malware in for it to happen. That means downloading and knowingly giving your password for it to download. Mac provides all the protection you need with SIP (System Integrity Protection).I This also includes XProtect which has malware definitions updated when Apple finds a new threat and scans your Mac invisibly. The Malware Removal Tool (MRT) introduced in El Capitan will remove commonly found recent malware that the user has somehow managed to already install. It runs at every reboot.
Ars Technica Keep your security set to “App Store and identified developers” Don’t download software from third party sites.If you use torrents, don't. Torrents are a good way to pick up malware because it can hitchhike in on a download package and you’ll never know it. Safari pop-ups are different and easier to deal with. In Safari 9.1 and later just close the window. For earlier versions force quit and hold the shift key while restarting Safari. Finally, do not get fooled by products that claim to clean, virus check or optimize your Mac.
If you do happen to download malware you can use to get rid of it. Malwarebytes was developed by one of our own colleagues here in ASC. It gets rave reviews and is about the most proven anti-malware software for Mac. The statements here support with overwhelming evidence the AV development for Mac uses concepts that are outlined by Microsoft Windows. Since OS X/Mac OS is not a Microsoft product and a litany of other findings the conclusion of the majority of volunteers here is that using a 3rd party Mac Anti-Virus package is not advised at this time and should be avoided for a number of reasons. The evidence here is gleaned from citing these forms and other forums as I have volutneered several thousand hours to Mac owners experiencing a variety of issues.
In addition I have also been active in Corporate IT for large corporations and worked predominantly Macintosh Computers, but I also have extensive Windows, Windows Server and Unix training. Currently there are none (e.g Zero) variants of an actual OS X/Mac OS virus in the wild found by any credible securities lab in the world. That may change tomorrow, however it's still the case now. 3rd party Mac AV products, this includes all 'Windows' credible titles and items sold in the App Store have not had the extensive testing as they have had with Windows development. 3rd party Mac AV products have had a fraction of development time by a fraction of developers. Some 3rd party Mac AV products are compiled from Windows code despite the fact OS X/Mac OS is not a Microsoft product and does not rely on the same components to be exploited.
3rd party Mac AV products hae never been tested with an actual Mac variant if one were to exist so its ability to deal with it is in question. 3rd party Mac AV products have been repeatedly found not to remove the most basic of adware and malware from Macs when a system scan shows they are present and those infections are found. In this event many of us suggest Etrecheck and/or Malwarebytes for Mac as neither of these products stay resident and their functionality is for removing adware/malware when it is already present and can be detected. However as stated these titles do not interfere with OS X because they are not designed to run interference with OS X/Mac OS. 3rd party Mac AV products have a history of false positives that can cause sever damage to OS X/Mac OS by erroneously detecting working components as compromised then causing the system to fail. 3rd party Mac AV products should not be used to protect Windows systems as their ability to compromise working files and not detect actual compromised files could cause futher problems with a Window solution that generally has far more flexibility due to years of development from knowledgable Windows developers. 3rd party Mac AV product developers do not work along side Apple developers as they often do with Microsoft developers.
Microsoft goes to great lengths to describe what their securities patches fix, Apple does not disclose their fixes to anyone. Keeping your Mac up-to-date is the single best software policy against possible attacks at this time. Smart browsing habits are invaluable to limiting any system, Mac, Windows or Other, from being attacked by malicious software. If you are habitually going to websites or using software that offers pay-for content for free expect the likelihood of any system being compromised is a far higher possibility then when you avoid that. All 3rd party Mac AV products can and will interfere with OS's ability to maintain itself. They have been cited on these forums as causing serious problems running in OS X/Mac OS ranging from slowdowns to outright kernel panics that freeze the OS and loosing any work you did not save. The forums are writhe with posts from a variety of users on different Mac computers and variants of OS X who have repeatedly had issue.
In fact no post here with an issue was not resolved when the 3rd party Mac AV product was removed, either by itself or another fraud product. I'm gonna knock you out!
Momma said knock you out! Johnbear1952 wrote: The best I have seen for AntiVirus and Adware is AntiVirus Thor that you can get on App Store. Antivirus Thor is a scam app. I've actually tested it against a bunch of malware and adware samples, and it detected none of them. It has already been removed from the App Store once over this, and it is detected as a potentially unwanted program (PUP) by Malwarebytes. Don't use any anti-virus software from the Mac App Store. A very high percentage of all such software on the Mac App Store right now is scam software.
