In some cases, your browser may automatically download and launch the installer for this malicious software. Delete the installer immediately using the steps below. Malware also installs a login item in your account in System Preferences.

Removal of the login item is not necessary, but you can remove it by following the steps below. User should exercise caution any time they are asked to enter sensitive personal information online.

How to recognize a virus on Mac

Information about products not manufactured by Apple, or independent websites not controlled or tested by Apple, is provided without recommendation or endorsement. Since you can encounter threats by visiting compromised or malicious websites, receiving virus-laden attachments, or accessing USB drives with malware, good AV software should scan on a continuous basis unless you configure it otherwise.

And ideally, files identified as malicious should be quarantined into a special storage area managed by the AV software, with the option to automatically delete files known to be malware or repair normal documents that also carry devious payloads. Great AV suites also will monitor the filesystem for certain kinds of changes.

Ransomware—which is malware that will rapidly encrypt user files like documents and mailboxes and then delete the originals—has become a huge moneymaker on other platforms. Detecting this pattern and halting it before any files are unavailable should be possible without an anti-malware system knowing the specific innards of a ransomware virus.

Sophos, our top pick, includes this feature in the Home Premium version of its update. Other vendors, like Avast and Trend Micro Antivirus, offer an alternative feature that allows you to whitelist programs allowed to manipulate files in specific directories.

Good antivirus software should also use minimal computational resources. Beyond these primary features, an easy-to-navigate interface and extra features are worth factoring into your decision. Some AV software are full-fledged suites that offer additional options like backup service for essential files, a password manager, parental controls, anti-tracking and privacy modes or options, a more advanced firewall, and the blocking of Potentially Unwanted Applications PUAs.

Each software package is evaluated creating a clean installation of macOS Mojave, cloning it for each AV product, and then booting separately into each one to install a different package. In addition to visiting malicious websites, downloading known malicious software, and even running said malware, we also reference the most recent reports from two labs that regularly cover macOS malware: These laboratories test AV software against sets of known malware as well as products that are grouped as potentially unwanted applications like adware.

Because the testing effectively looks at a combination of virus databases and behavior, they remain good gauges even after many months.

When an antivirus software package lacks a rating from a known security research lab, we do more extensive testing with real malware. Finally, while we gave props for a lot of different features and behaviors, we marked products down if they lacked any or all of the following:. First, an antivirus product may upload the complete text of files flagged to the cloud, where it can be analyzed by separate tools hosted there. This practice is normal and sensible: Some malware can detect when a running process may examine it, and will then engage in subterfuge.

Antivirus software makers also can access their massive databases to examine files with characteristics that trigger their algorithms—certain elements that match known malware. As a result, security researchers discover new viruses, worms, Trojans horses, and the like. Where appropriate, we noted privacy policy issues in individual reviews. Second, this software may also rely partly or entirely on cloud-based checks of URLs, malware, and the like. Companies vary on their disclosure of such policies, and may not let you opt out of this kind of sharing.

We note issues in each review as available. In some cases, you can opt out of this information gathering. Sophos Home Premium has the most extensive and up-to-date approach to fighting malware at an unbeatable price. The end goal for both is the same: MacOS High Sierra versions The virus was found by Cybereason to be hidden in cracked versions of Adobe Photoshop and Microsoft Office that are popular on torrent sites.

It targets Mac users with social engineering methods such as malicious emails and website pop-ups.

MaMi is also capable of taking screenshots, downloading and uploading files, executing commands, and generating mouse events. Since it arrived on the scene in April , Apple has revoked the developer certificate and updated XProtect, however, it remains one to look out for. X-agent is classic malware capable of stealing your passwords and iPhone backups and taking screenshots of sensitive data. While its name suggests it could be a useful app, MacDownloader is a very nasty piece of malware programmed to attack the US defense industry.

By clicking on the alert and entering your admin password, MacDownloader lifts sensitive data, including passwords and credit card details, and sends it to a remote server. It was bundled in with the torrent client Transmission version 2. Once document and data files are encrypted, KeRanger demands payment in bitcoin for the malware to be removed.

The Goto fail bug was a bit of an embarrassing one for Apple in that the security flaw was as a result of its own doing. The flaw put communications sent over unsecured Wi-Fi the hotspots you use at the mall and in coffee shops at risk, allowing hackers to intercept passwords, credit card details, and other sensitive information. Apple has since patched the issue on macOS, but it certainly makes you think twice about how you browse the web on your MacBook in a public place. In January , it was announced that there was a flaw in Intel chips used in Macs, giving rise to the dastardly duo of Meltdown and Spectre.

The Meltdown and Spectre issues take advantage of a modern CPU performance feature called speculative execution. Speculative execution improves speed by operating on multiple instructions at once—possibly in a different order than when they entered the CPU. To increase performance, the CPU predicts which path of a branch is most likely to be taken, and will speculatively continue execution down that path even before the branch is completed.

If the prediction was wrong, this speculative execution is rolled back in a way that is intended to be invisible to software. The Meltdown and Spectre exploitation techniques abuse speculative execution to access privileged memory—including that of the kernel—from a less-privileged user process such as a malicious app running on a device. Meltdown and Spectre affects all Mac systems, but Apple insists there are no known exploits currently impacting customers. The flaw, which was discovered by software developer Lemi Orhan Ergin, allowed anyone to gain root access to a system by leaving the password field blank and trying multiple times in a row.

Scary thought, huh?
