Antivirus for Mac OS X Maverick - Apple Community

If Java is installed, disable it — not JavaScript —in your browsers. Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-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. The rest of this comment concerns what you should not do to protect yourself.

Never install any commercial "anti-virus" AV or "Internet security" products for the Mac, as they are all worse than useless. If you need to be able to detect Windows malware in your files, use one of the free security apps in the Mac App Store—nothing else. This technique is a proven failure , as a major AV software vendor has admitted. Most attacks are "zero-day"—that is, previously unknown. Recognition-based AV does not defend against such attacks , and the enterprise IT industry is coming to the realization that traditional AV software is worthless.

Malware is downloaded from the network; it doesn't materialize from nowhere. In order to meet that nonexistent threat, commercial AV 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. An AV product from the App Store, such as "ClamXav," has the same drawback as the commercial suites of being always out of date, but it does not inject low-level code into the operating system.

That doesn't mean it's entirely harmless. 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. It's useful, if at all, only for detecting Windows malware, and even for that use it's not really effective, because new Windows malware is emerging much faster than OS X malware. Windows malware can't harm you directly unless, of course, you use Windows. Just don't pass it on to anyone else.

A malicious attachment in email is usually easy to recognize by the name alone. An actual example:. You don't need software to tell you that's a Windows trojan. Software may be able to tell you which trojan it is, but who cares? In practice, there's no reason to use recognition software unless an organizational policy requires it. Windows malware is so widespread that you should assume it's in every email attachment until proven otherwise. Nevertheless, ClamXav or a similar product from the App Store may serve a purpose if it satisfies an ill-informed network administrator who says you must run some kind of AV application.

It's free and it won't handicap the system.

The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have all the disadvantages mentioned in section 7. 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. As a Mac user, you don't have to live in fear that your computer may be infected every time you install software, read email, or visit a web page. But neither can you assume that you will always be safe from exploitation, no matter what you do. Navigating the Internet is like walking the streets of a big city. It's as safe or as dangerous as you choose to make it. The greatest harm done by security software is precisely its selling point: They may then feel safe enough to take risks from which the software doesn't protect them.

Nothing can lessen the need for safe computing practices.

Desktops Speciality level out of ten: See these Apple articles: From user Joe Bailey comes this equally useful advice: The facts are: There is no anti-malware that can detect everything targeting the Mac. Internet popups saying the FBI, NSA, Microsoft, your ISP has detected malware on your computer is intended to entice you to install their malware thinking it is a protection against malware.

Some of the anti-malware products on the market are worse than the malware from which they purport to protect you. Be cautious where you go on the internet. Only download anything from sites you know are safe. Avoid links you receive in email, always be suspicious even if you get something you think is from a friend, but you were not expecting. If there is any question in your mind, then assume it is malware. Reply Helpful Thread reply - more options Link to this Post.
