avast! Free Antivirus for Mac version 9

Avast For Mac
Free Avast Internet Security

Avast Internet Security is the basic version, a step up from the Avast Free Antivirus. However even this basic level software packs a lot of utilities. Avast’s support was responsive and helpful when I had an issue connecting my online account with my software, and the help and documentation on the website is very well laid out and clear. Avast tied with Kaspersky Internet Security for Mac, Sophos Home for Mac and Norton Security, which also all scored 99.17 percent, and did better than Avira Free Antivirus for Mac, which stopped.

Pros
Certified by one independent testing lab. Free. Speedy full scan. Network security scanner. Password manager. Website rating. Active Do Not Track.
Cons
Poor scores in phishing protection test. Password manager includes only basic features. SiteCorrect feature did not work in testing.
Bottom Line
Avast Security (for Mac) delivers effective malware protection along with unusual bonus features. It tanks our antiphishing test, but this free utility is still worth a look.

For years, Mac users basked in the mystique of virus-free computing. It wasn't true, alas, and as time goes on we see more and more Mac-specific malware attacks. The situation may not be nearly as bad as for Window or Android, but prudence still dictates that you install antivirus protection on your Macs as well. Avast Security offers Macs protection against malware along with advanced features including a password manager and a network security scanner, all for a cost of exactly nothing.

Installation went quickly, though I did find I had to separately activate the password manager and the Online Security browser extension from the Tools page. You'll also find Avast's SecureLine VPN on that page, but it's not free like the others. When you click to activate, you get a choice of signing up for $2.99 per month or starting a 30-day trial.

The product's spacious main window features a large status indicator centered in an otherwise-empty white region, with a menu down the left side. It's a very different appearance from Avast Free Antivirus on Windows, which uses pops of purple and green on a dark gray background.

Pricing and OS Support

Review Avast Internet Security Free For Mac

Like Bitdefender and Kaspersky, Avast supports macOS versions back to 10.9 Mavericks. If you have an antique Mac that for some reason can't even run Mavericks, consider ESET Cyber Security (for Mac), ProtectWorks, or ClamXAV (for Mac) all of which support versions from 10.6 (Snow Leopard) on. At the other end of the spectrum, Avira, Trend Micro, and Symantec require macOS 10.11 (El Capitan) or better.

Like Sophos and Avira, Avast offers full antivirus protection for free. Avast Security Pro (for Mac) costs $59.99 per year for one license or $69.99 for three. The Pro edition adds ransomware protection and real-time notification when new devices connect to your network. The free edition is strictly for non-commercial use; in a business setting, you must pay up.

Good Malware Protection Scores

When reviewing a Windows antivirus utility, I report how it scored with four independent antivirus testing labs. The very best products earn top scores from all four labs. But even if no test results exist, I can run my own hands-on tests using real-world malware and malware-hosting URLs.

It took years to develop my hands-on tools and tests for Windows. Most of them don't carry over to the macOS platform. Hence lab results become extremely important for my Mac antivirus reviews. Two of the labs I follow, AV-Test Institute and AV-Comparatives, test Mac antivirus, and Avast participates with one of them.

Experts at AV-Comparatives test Mac antivirus products using the latest macOS malware. They also evaluate each product's ability to detect Windows malware. Why? While a Trojan written for Windows wouldn't run on a Mac, the Mac could serve as a carrier.

Avast managed 99.9 percent protection against Mac malware. That's very good—better than most. However, Bitdefender and Kaspersky exhibited 100 percent protection. In the Windows malware test, Avast detected 100 percent of the samples. Most competing products also took 100 percent. However, Webroot only caught 75 percent, and Intego Mac Internet Security X9 got just 18 percent. Like most tested products, Avast received certification from AV-Comparatives for Mac antivirus protection.

Having one certification is good; having two is better. Bitdefender, Kaspersky, and Sophos are among the products that received certifications from both labs for Mac malware protection.

Scan Choices

Avast offers several scans to improve your Mac's security. A full scan on the Apple MacBook Air 13-Inch that I use for testing took 14.5 minutes, just a hair over Intego's 14 minutes, and quicker than the 18 minutes required by Avira. The average for recent products is 24 minutes, so Avast proved quite speedy. Norton is the current speed champ, completing a full scan in 10 minutes.

Avast For Mac

There's a separate scan for removable volumes, though you can configure the full scan to include them. I scanned a thumb drive containing my Windows malware collection and found that it quarantined 85 percent of them. For comparison, Avira detected 82 percent of these, while Sophos Home (for Mac) wiped out every single one.

There's no predefined quick scan, which makes sense given the speed of the full scan. The custom scan settings confused me, though. As with the full scan, you can add file locations to exclude from scanning, and configure it to scan Time Machine backups. But the full scan's settings include those options, and also let you include removable volumes and network volumes, while the custom scan's settings do not. Puzzling.

You can schedule a daily, weekly, or monthly scan if desired. Settings for a scheduled scan include two additional choices. You can set it to skip scanning if your device is running on batteries, and you can have it wake from sleep if necessary, to perform its scheduled scan. Avira Free Antivirus for Mac not only offers scheduled scanning, it defaults to a weekly scan with no effort on your part. Sophos skips scheduled scanning, relying instead on real-time protection.

Network Security Scan

The final scan choice doesn't look for malware. Rather, it collects information about all the devices on your network and flags any security problems. On my own network, the scan finished in just under three minutes.

The scanner correctly reported that my main router has an open port that could theoretically become a point of attack. It's true that the port is open, as my ISP uses it to run remote diagnostics when necessary. But that function requires a key that only the ISP has.

More interestingly, it found serious problems with a network storage device (fortunately, one that I'm not currently using). Not only does this device have numerous open ports, it's vulnerable to a buffer overrun attack. Avast advised updating the firmware; I just unplugged it.

The report also serves as a list of everything that's connected to your network, identifying each by name and type. It's similar to the output of Bitdefender Home Scanner. With both products, I found devices with names like unknown6542990b6483—not much help! Bitdefender includes an option to edit the name and type, and it remembers your edits in subsequent scans. I'd like to see that ability in Avast.

Excellent Phishing Protection in Chrome and Firefox

In the Windows realm, one thing that differentiates Avast's premium product is better protection against phishing sites, those fraudulent sites that imitate secure sites and try to steal your login credentials. The free Windows edition scored very poorly, while the premium edition did an extremely good job. Based on initial round of testing, the Mac product's phishing protection, both free and Pro, seemed to match that of the free Windows product, meaning it's not very good.
