It depends on what virus or malware your Mac is infected with. Common malware and viruses can be easily removed by antivirus applications. Some are harder to deal with, such as bootkits which infect the boot sectors of your Mac and viruses that target your Mac’s Extensible Firmware Interface or EFI (equivalent to BIOS in Windows OS). The wicar.org website was designed to test the correct operation your anti-virus / anti-malware software. The name 'WICAR' is derived from the industry standard EICAR anti-virus test file, which is a non-dangerous file that all anti-virus products flag as a real virus and quarantine or act upon as such.By being able to execute a test virus program safely, the end user or network.

Who needs the Anti-Malware Testfile

Version of 7 September 2006
If you are active in the anti-virus research field, then you will regularly receive requests for virus samples. Some requests are easy to deal with: they come from fellow-researchers whom you know well, and whom you trust. Using strong encryption, you can send them what they have asked for by almost any medium (including across the Internet) without any real risk.
Other requests come from people you have never heard from before. There are relatively few laws (though some countries do have them) preventing the secure exchange of viruses between consenting individuals, though it is clearly irresponsible for you simply to make viruses available to anyone who asks. Your best response to a request from an unknown person is simply to decline politely.
A third set of requests come from exactly the people you might think would be least likely to want viruses „users of anti-virus software“. They want some way of checking that they have deployed their software correctly, or of deliberately generating a „virus incident in order to test their corporate procedures, or of showing others in the organisation what they would see if they were hit by a virus“.
Reasons for testing anti-virus software
Reasons for testing anti-virus software
Obviously, there is considerable intellectual justification for testing anti-virus software against real viruses. If you are an anti-virus vendor, then you do this (or should do it!) before every release of your product, in order to ensure that it really works. However, you do not (or should not!) perform your tests in a „real“ environment. You use (or should use!) a secure, controlled and independent laboratory environment within which your virus collection is maintained.
Using real viruses for testing in the real world is rather like setting fire to the dustbin in your office to see whether the smoke detector is working. Such a test will give meaningful results, but with unappealing, unacceptable risks.
Since it is unacceptable for you to send out real viruses for test or demonstration purposes, you need a file that can safely be passed around and which is obviously non-viral, but which your anti-virus software will react to as if it were a virus.
If your test file is a program, then it should also produce sensible results if it is executed. Also, because you probably want to avoid shipping a pseudo-viral file along with your anti-virus product, your test file should be short and simple, so that your customers can easily create copies of it for themselves.
The good news is that such a test file already exists. A number of anti-virus researchers have already worked together to produce a file that their (and many other) products „detect“ as if it were a virus.
Agreeing on one file for such purposes simplifies matters for users: in the past, most vendors had their own pseudo-viral test files which their product would react to, but which other products would ignore.
The Anti-Malware Testfile
The Anti-Malware Testfile
This test file has been provided to EICAR for distribution as the „EICAR Standard Anti-Virus Test File“, and it satisfies all the criteria listed above. It is safe to pass around, because it is not a virus, and does not include any fragments of viral code. Most products react to it as if it were a virus (though they typically report it with an obvious name, such as „EICAR-AV-Test“).
The file is a legitimate DOS program, and produces sensible results when run (it prints the message „EICAR-STANDARD-ANTIVIRUS-TEST-FILE!“).
It is also short and simple – in fact, it consists entirely of printable ASCII characters, so that it can easily be created with a regular text editor. Any anti-virus product that supports the EICAR test file should detect it in any file providing that the file starts with the following 68 characters, and is exactly 68 bytes long:
X5O!P%@AP[4PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*
The first 68 characters is the known string. It may be optionally appended by any combination of whitespace characters with the total file length not exceeding 128 characters. The only whitespace characters allowed are the space character, tab, LF, CR, CTRL-Z. To keep things simple the file uses only upper case letters, digits and punctuation marks, and does not include spaces. The only thing to watch out for when typing in the test file is that the third character is the capital letter „O“, not the digit zero.
You are encouraged to make use of the EICAR test file. If you are aware of people who are looking for real viruses „for test purposes“, bring the test file to their attention. If you are aware of people who are discussing the possibility of an industry-standard test file, tell them about www.eicar.org, and point them at this article.
Download Anti Malware Testfile
In order to facilitate various scenarios, we provide 4 files for download. The first, eicar.com, contains the ASCII string as described above. The second file, eicar.com.txt, is a copy of this file with a different filename. Some readers reported problems when downloading the first file, which can be circumvented when using the second version. Just download and rename the file to „eicar.com“. That will do the trick. The third version contains the test file inside a zip archive. A good anti-virus scanner will spot a ‚virus‘ inside an archive. The last version is a zip archive containing the third file. This file can be used to see whether the virus scanner checks archives more than only one level deep.
Test For Virus On Mac
Once downloaded run your AV scanner. It should detect at least the file „eicar.com“. Good scanners will detect the ‚virus‘ in the single zip archive and may be even in the double zip archive. Once detected the scanner might not allow you any access to the file(s) anymore. You might not even be allowed by the scanner to delete these files. This is caused by the scanner which puts the file into quarantaine. The test file will be treated just like any other real virus infected file. Read the user’s manual of your AV scanner what to do or contact the vendor/manufacturer of your AV scanner.

How to delete the test file from your PC
We understand (from the many emails we receive) that it might be difficult for you to delete the test file from your PC. After all, your scanner believes it is a virus infected file and does not allow you to access it anymore. At this point we must refer to our standard answer concerning support for the test file. We are sorry to tell you that EICAR cannot and will not provide AV scanner specific support. The best source to get such information from is the vendor of the tool which you purchased.
Please contact the support people of your vendor. They have the required expertise to help you in the usage of the tool. Needless to say that you should have read the user’s manual first before contacting them.
Do you own a Mac? If so, you might have the common perception that they’re more secure from internet threats than Windows PCs. Unfortunately, this isn’t the case. The truth is that Macs have historically not been targeted by hackers as frequently as Windows systems, simply because there were fewer to attack, so it didn’t make financial sense for the bad guys.
But this is changing: as Macs become more popular, cyber-criminals are increasingly turning their attention towards the platform. That’s bad news for Mac owners.
According to some estimates, Mac-specific malware soared 270% in 2017 over the prior year. Threats are still not as widespread as on Windows PCs, but you only need to get hit once and it could have a serious impact: leading to the loss of precious files and pictures, identity theft, or even locking you out of your machine altogether.
With that in mind, we’ve put together this blog, briefing you on things you need to know: where some of the main risks are for Mac owners, and how you can keep your machine and data safe from harm with Trend Micro.
A helping hand
Fortunately, there are some built-in protections to help keep your Mac safe from internet threats. For one, its operating system is based on the Unix platform, which is more secure by design than Windows. However, no OS is completely impervious to vulnerabilities and threats. That’s why Apple has added a few features to improve security. These include:
XProtect: A built-in malware scanning tool that works in the background. If you try to open a file – for example, by opening an email attachment from an unrecognized sender, or downloading an app – it will check the file against a blacklist of known malware and flag anything suspicious. The tool requires no user interaction to work; it’s on by default and shouldn’t slow your Mac down.
However, its list of malware is not exhaustive, and there are many threats in the wild which have never been seen before, and so could bypass this filter. Its effectiveness could also suffer if you don’t keep it up-to-date by upgrading to the latest macOS version.
Gatekeeper: This is a built-in tool that prevents users from downloading unapproved Mac apps. When you’re on the official Mac App Store this isn’t an issue, of course. But if you’re on a third-party marketplace, there could be malware-laden applications masquerading as legitimate software. If the app hasn’t been digitally signed and approved by Apple, Gatekeeper will alert the user. Your Mac’s password protection helps here too, for gatekeeping purchases and free downloads.
Sandboxing: Approved macOS apps also contain a “sandboxing” feature which ensures they’re isolated from the critical parts of your machine. This provides further security in case they are hijacked by attackers.
Anti-phishing: Phishing attacks are commonplace today. They often aim to trick the recipient of an email into clicking on a malicious link or will take you to a specially crafted site where they ask for log-ins, financial and other personal data. The site could also download ransomware, to lock your files or Mac, until you pay the price. Apple’s Safari browser has built-in anti-phishing technology to spot some of these sites.
Plug-ins: Certain third-party technology platforms can also introduce extra risk to Mac users. That’s why macOS is designed to block plug-ins such as Adobe Flash Player, Silverlight, QuickTime and Oracle Java if they aren’t updated to the latest, most secure version.
FileVault 2: This feature offers full disk encryption to keep your data protected in the event that a hacker tries to access the information on your machine.
MacOS threats on the rise
However, despite these protections, the bad guys are getting more determined and advanced in how they target macOS users. There was an estimated 29 percent increase in vulnerabilities on the platform reported in 2017, while Mac malware samples have skyrocketed (see the chart below). Hackers are adept at exploiting software flaws to spread malware which could steal your data, snoop on your internet browsing, flood your screen with annoying ads, and, as ransomware, even lock you out of your machine completely.

Reports also suggest US users are more affected by macOS malware than any others. A quarter of all global threats affecting the platform are aimed at them.
Here are just a few recent threats affecting Mac users:
Meltdown/Spectre: Billed as one of the most serious cyber-threats in recent memory, these processor flaws could allow sophisticated hackers to read your Mac’s memory. The result? Although there are no reports of these vulnerabilities being exploited as yet, the potential is there for attackers to steal any data that has been stored on your machine.
Word macro viruses: For a long time confined to the PC space, these threats also affect Mac users. Macro programs embedded into Word and other documents can contain malware. If they’ve been enabled to automatically run this could land you in trouble, downloading info-stealing malware, ransomware and more.
Fruitfly: Discovered in 2017, it’s thought the Fruitfly malware could have been circulating for as many as 13 years. It’s designed to capture screenshots and webcam images and infect other devices on the same network. Dubbed “creepware,” it’s thought the program lifted millions of images from infected computers.
OSX/Ransom: Again discovered in 2017, OSX/Ransom-A (popularly known as MacRansom), the ransomware follows the now-familiar pattern of encrypting your files, then threatens you with the message that if you don’t pay the ransom within 7 days, even the cybercriminals who created the malware won’t be able to decrypt your files.
Test For Virus On Mac
OSX/MaMi: One of the first threats of 2018, OSX/MaMi is designed to route your internet traffic through malicious servers, where the attackers can steal your log-ins and other sensitive information.
MacDownloader: This malware was first discovered hidden in a fake Adobe Flash update. If a user clicks through they’ll be told there’s adware on their machine and asked for their Mac password. Divulging it will allow the hackers to steal your usernames, passwords, PINs, credit card numbers and more.

Trend Micro Antivirus for Mac
The good news is that there are third-party tools available to help you enhance the built-in security of your Mac to boost protection against these rising threat levels. The truth is that while Apple does a good job of providing as much protection as it can, security is just one of the things that Apple’s focused on. Security vendors like Trend Micro are laser-focused on one thing only: threat protection for users and businesses. Trend Micro works around the clock to develop advanced protection, not just against current threats but also to reduce the risks posed by previously unseen web and social network threats, phishing emails, and ransomware.
Trend Micro Antivirus for Mac is just such a tool. Leveraging our industry-leading Smart Protection Network and the latest machine learning technology, it’s designed to keep scams out of your inbox, block malware, prevent you from visiting dangerous sites and much more.
