Is Avg Free For Mac

Mac users often ask whether they should install 'anti-virus' (AV) software. The usual answer is 'no.' That answer is right, but it may give the wrong impression that there is no threat from what are loosely called 'viruses.' There is a threat, and you need to educate yourself about it.

The free AVG AntiVirus protects against Mac, Windows, and mobile malware, but that's about all, and its antiphishing component tanked in our hands-on testing. $71.99/Year at AVG. AVG offers an inclusive list of features for both the free and premium paid versions of its antivirus software on its website. The AVG review of free features includes the following: Antivirus protection against viruses, spyware, and malware; Protection for both Mac and Android devices; Access to the AVG.

1. This is a comment on what you should—and should not—do to protect yourself from malicious software ('malware') that circulates on the Internet and gets onto a computer as an unintended consequence of the user's actions.

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 computer, or who has been able to take control of it remotely. That threat is in a different category, and there's no easy way to defend against it. AV software is not intended to, and does not, defend against such attacks.

The comment is long because the issue is complex. The key points are in sections 5, 6, and 10.

OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.

2. 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. Internally Apple calls it 'XProtect.'

The malware recognition database used by XProtect is automatically updated; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.

The following caveats apply to XProtect:

☞ It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.

☞ It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.

As new versions of OS X are released, it's not clear whether Apple will indefinitely continue to maintain the XProtect database of older versions such as 10.6. The security of obsolete system versions may eventually be degraded. Security updates to the code of obsolete systems will stop being released at some point, and that may leave them open to other kinds of attack besides malware.

3. Starting with OS X 10.7.5, there has been a second 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 been checked for security by Apple unless it comes from the 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. That may not mean much if the developer lives in a country with a weak legal system (see below.)

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 simply ignore the consequences of distributing codesigned malware.

☞ An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.

Apple has taken far too long to revoke the codesigning certificates of some known abusers, thereby diluting the value of Gatekeeper and the Developer ID program. Those lapses don't involve App Store products, however.

For the reasons given, App Store products, and—to a lesser extent—other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. 'Sandboxed' applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. Sandbox security is based on user input. Never click through any request for authorization without thinking.

4. Starting with OS X 10.8.3, a third layer of protection has been added: a 'Malware Removal Tool' (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is effective against known threats, but not against unknown ones. It notifies you if it finds malware, but otherwise there's no user interface to MRT.

5. The built-in security features of OS X reduce the risk of malware attack, but they are not, and never will be, complete protection. Malware is a problem of human behavior, not machine behavior, and no technological fix alone is going to solve it. Trusting software to protect you will only make you more vulnerable.

The best defense is always going to be your own intelligence. With the possible exception of Java exploits, 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 Internet criminals. If you're better informed than they think you are, you'll win. That means, in practice, that you always stay within a safe harbor of computing practices. How do you know when you're leaving the safe harbor? Below are some warning signs of danger.

Software from an untrustworthy source

☞ Software with a corporate brand, such as Adobe Flash Player, doesn't come directly from the developer’s website. Do not trust an alert from any website to update Flash, or your browser, or any other software. A genuine alert that Flash is outdated and blocked is shown on this support page. Follow the instructions on the support page in that case. Otherwise, assume that the alert is fake and someone is trying to scam you into installing malware. If you see such alerts on more than one website, ask for instructions.

☞ Software of any kind is distributed via BitTorrent, or Usenet, or on a website that also distributes pirated music or movies.

☞ Rogue websites such as Softonic, Soft32, and CNET Download distribute free applications that have been packaged in a superfluous 'installer.'


☞ The software is advertised by means of spam or intrusive web ads. Any ad, on any site, that includes a direct link to a download should be ignored.

Software that is plainly illegal or does something illegal

☞ High-priced commercial software such as Photoshop is 'cracked' or 'free.'

☞ An application helps you to infringe copyright, for instance by circumventing the copy protection on commercial software, or saving streamed media for reuse without permission. All 'YouTube downloaders' are in this category, though not all are necessarily malicious.

Conditional or unsolicited offers from strangers

☞ A telephone caller or a web page tells you that you have a “virus” and offers to help you remove it. (Some reputable websites did legitimately warn visitors who were infected with the 'DNSChanger' malware. That exception to this rule no longer applies.)

☞ A web site offers free content such as video or music, but to use it you must install a “codec,” “plug-in,” 'player,' 'downloader,' 'extractor,' or “certificate” that comes from that same site, or an unknown one.

☞ You win a prize in a contest you never entered.

☞ Someone on a message board such as this one is eager to help you, but only if you download an application of his choosing.

☞ A 'FREE WI-FI !!!' network advertises itself in a public place such as an airport, but is not provided by the management.

☞ Anything online that you would expect to pay for is 'free.'

Unexpected events

☞ A file is downloaded automatically when you visit a web page, with no other action on your part. Delete any such file without opening it.

Avg Free For Mac

☞ You open what you think is a document and get an alert that it's 'an application downloaded from the Internet.' Click Cancel and delete the file. Even if you don't get the alert, you should still delete any file that isn't what you expected it to be.

☞ An application does something you don't expect, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.

☞ Software is attached to email that you didn't request, even if it comes (or seems to come) from someone you trust.

I don't say that leaving the safe harbor just once will necessarily result in disaster, but making a habit of it will weaken your defenses against malware attack. Any of the above scenarios should, at the very least, make you uncomfortable.

6. 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 always a bad idea, and Java's developers have proven themselves incapable of 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, client-side Java on the Web is obsolete and 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. Forget about playing games or other non-essential uses of Java.

Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. 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 padlock icon in the address bar when visiting a secure site.

Stay within the safe harbor, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself.

7. Never install any commercial 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.

Why shouldn't you use commercial AV products?

☞ To recognize malware, the software depends on a database of known threats, which is always at least a day out of date. 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.

☞ Its 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, 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.

☞ By modifying the operating system, the software may also create weaknessesthat could be exploited by malware attackers.

☞ Most importantly, a false sense of security is dangerous.

8. 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.

An AV app is not needed, and cannot be relied upon, for protection against OS X malware. 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:

London Terror Moovie.avi [124 spaces] Checked By Norton Antivirus.exe

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.

9. 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.

10. 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 can be as safe or as dangerous as you choose to make it. The greatest harm done by security software is precisely its selling point: it makes people feel safe. 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.

Developer(s)AVG Technologies
Stable release

19.3.3084 (March 11, 2019; 19 months ago[1])

6.17.2 (March 15, 2019; 19 months ago[2]) [±]
Operating systemWindows XP and later, macOS, Android
TypeAntivirus software

AVG AntiVirus (previously known as AVG, an abbreviation of Anti-Virus Guard) is a line of antivirus software developed by AVG Technologies, a subsidiary of Avast.[3][4] It is available for Windows, macOS and Android.


The brand AVG comes from Grisoft's first product, Anti-Virus Guard, launched in 1992 in the Czech Republic. In 1997, the first AVG licenses were sold in Germany and the UK. AVG was introduced in the US in 1998.[5]

The AVG Free Edition helped raise awareness of the AVG product line.[6] In 2006, the AVG security package grew to include anti-spyware as AVG Technologies acquired ewido Networks, an anti-spyware group. AVG Technologies acquired Exploit Prevention Labs (XPL) in December 2007 and incorporated that company's LinkScanner safe search and surf technology into the AVG 8.0 security product range released in March 2008. In January 2009, AVG Technologies acquired Sana Security, a developer of identity theft prevention software. This software was incorporated into the AVG security product range in March 2009.

According to AVG Technologies, the company has more than 200 million active users worldwide, including more than 100 million who use their products and services on mobile devices.[7]

Avg Antivirus Free For Mac

On 7 July 2016, Avast announced an agreement to acquire AVG for $1.3 billion.[8]

Platform support

AVG provides AVG AntiVirus Free for Windows, AVG AntiVirus for Mac for macOS and AVG AntiVirus for Android for Android devices. All are freemium products: They are free to download, install, update and use, but for technical support a premium plan must be purchased.

AVG stopped providing new features for Windows XP and Windows Vista in January 2019. New versions require Windows 7 or later; virus definitions are still provided for previous versions.[9]


AVG features most of the common functions available in modern antivirus and Internet security programs, including periodic scans, scans of sent and received emails (including adding footers to the emails indicating this), the ability to repair some virus-infected files, and a quarantine area (virus vault) in which infected files are held.


The patent pending LinkScanner technology acquired from Exploit Prevention Labs and built into most AVG products, provides real-time updated protection against exploits and drive-by downloads. LinkScanner includes: Search-Shield – a safe search component that places safety ratings next to each link in Google, Yahoo! and MSN search results; plus Active Surf-Shield – a safe surf component that scans the contents of a web site in real-time to ensure it's safe being opened.[10] Concerns regarding web analytics have made LinkScanner a controversial component (see 'LinkScanner concerns' below).

LinkScanner concerns

When AVG 8.0 was first released, its LinkScanner safe search feature was shown to cause an increase in traffic on websites that appear high in search engine results pages. Since LinkScanner disguises the scans as coming from an Internet Explorer 6 browser when it prescans each site listed in the search results, we site usage logs showed incorrect and overinflated site visitor statistics. The prescanning of every link in search results also caused websites to transfer more data than usual, resulting in higher bandwidth usage for web site operators and slow performance for users.[11] AVG initially said that site administrators would be able to filter the LinkScanner traffic out of their site statistics, leaving the problem of excess bandwidth usage still to be solved.[12] Pay-per-click advertising was not affected by the increase in traffic.[13]

AVG Online Shield

AVG Online Shield is a feature designed to check files and ensure that they are safe. AVG Online Shield also ensures the safety of exchanging files via instant messengers and VoIP clients.[14]

In response to complaints, AVG announced that as of 9 July 2008 'Search-Shield will no longer scan each search result online for new exploits, which was causing the spikes that webmasters addressed with us',[15] releasing a new build on that date that applies a local blacklist, then prefetches and scans only those links clicked on by the user.[16]


As of 2014, there are numerous reports dating back to 2012 that the AVG SafeGuard Toolbar installs itself without the consent of the user, as a side effect of installing other applications. The toolbar program appears to cause significant RAM issues and can be considered an intrusive potentially unwanted program (PUP). Once installed, the AVG toolbar is virtually impossible to remove. The toolbar uninstaller does not function, instead re-installing the add-on if manually removed. Consequently, many discussions and blog posts have described complex procedures for removal of the AVG toolbar, each with very mixed results.[17][18][19][20][21][22]

In September 2015, AVG announced that it would start tracking users for profit, analyzing their data for sale to the advertising industry. This measure received criticism from consumers, the press and security industry, as many users intended to use the software in order to protect themselves from spyware and would not expect the functions of spyware to be 'hidden' in security software.[23]

In December 2015, the AVG Web TuneUp Google Chrome extension (automatically installed with AVG AntiVirus) was revealed to contain multiple critical security vulnerabilities.[24] Most notably, Chrome users' browsing history could be exposed to any website, cookies from any site the user has visited could be read by an attacker, and trivial cross-site scripting (XSS) issues could allow any website to execute arbitrary code (as another domain).

The XSS vulnerability allowed a user's mail from '' to be read by any website, or financial information to be read from the user's online banking site. The AVG team fixed this by only allowing '' and '' to execute these scripts. Despite this remediation, attackers could leverage any of these attacks if an XSS vulnerability was found on the AVG sites. As of April 2016, Web TuneUp was still not available for download from the AVG website.


AVG Antivirus Free 2012 was selected as PC Magazine Editors' Choice in the free antivirus category.[25] AVG AntiVirus Free 2015 received the Editor Choice badge of SoftChamp.[26]
