That means preventing the download, installation, or execution of malicious software.
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.
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.
