How We Tested

Avast For Mac Antivirus Free Download 2016

To find the best antivirus for Mac desktops and laptops, we evaluate ease of use, interface and performance impact, we installed each AV program on the same Late 2013 MacBook Pro with Retina Display running macOS 10.12 Sierra. It was powered by a 2.6-GHz Intel Core i7 processor and had 8GB of RAM and 70GB of data stored on a 512GB SSD.

We conducted our own tests in July and August 2017 based on how much each antivirus product affected our laptop's performance. To do this, we used our custom OpenOffice benchmark, which matches 20,000 names and addresses in a spreadsheet. We measured how long it took to run a quick scan and a full scan while the laptop crunched numbers in the background.

We assessed how easy each program was to use and the number of useful extra features it offered (including free add-on software). To gauge how effective each package was at stopping malware, we used the results of evaluations conducted in May 2017 by AV-TEST, a well-regarded independent product-testing lab in Germany, and results from other tests conducted in July 2017 by AV-Comparatives, a similarly well-respected firm in Austria.

Best Mac Antivirus

Reasons to Buy

Kaspersky Internet Security is the best antivirus for Macs because it offers both the lowest system impact and some of the best malware-detection rates recorded. It even provides extra security features, including parental controls and options to lock down your webcam and stop websites from tracking your browsing activity. If you're willing to pay to protect your Mac from malware, Kaspersky Internet Security is the best option available.

Best Free Mac Antivirus

Reasons to Buy

Avast Free Mac Security caught 99.9 percent of all malware, packs in a password manager, barely leaves a smudge on system impact and doesn't charge a dime. If only it caught 100 percent of malware, as Kaspersky did.

Reasons to Buy

Bitdefender Antivirus for Mac is one of only a few solutions we tested that offers perfect malware detection. Further, its modern, streamlined interface places on-demand scans front and center. Bitdefender has dropped from first place, though, because its system-impact scores don't match the flawless marks posted by Kaspersky.

Reasons to Avoid

Norton 360 Deluxe may offer excellent protection, but it charges more (after the first year) than its competitors do, without offering as many perks. Norton AntiVirus Plus offers similar protection for a single Mac, but with fewer perks. Still, both have always-on-call customer support.

Reasons to Avoid

If you're looking for the best antivirus for Mac without having to pay, AVG AntiVirus for Mac is not too shabby, with its 99.9 percent detection rate and easy-to-use design. Unfortunately, other free competitors provide extras (Sophos with parental controls, Avast's password manager) that AVG does not.

Best for Families

Reasons to Buy

With Sophos Home for Mac's simple interface and low system-performance impact, you'll barely realize the program is shielding you until you need it. Anyone with young children at home will find Sophos' parental controls useful, as they allow for remote scans and checks, and let you block sites by category. Sophos even keeps a log of when users try to reach banned pages. This program's major drawback, though, is its lackluster malware-detection rate.

Reasons to Buy

Once our favorite, Avira Free Antivirus for Mac is no longer the best antivirus for Mac. That's because it is a hair shy of perfection in its malware detection, and fell behind in system-performance testing, earning some of the higher performance impacts recorded.

Free Avast For Mac

While McAfee's unlimited licenses mean you can support a whole family of Macs (and PCs and Android devices, too), this program's lack of special features (for a paid version) make it hard to recommend. Further, we don't have malware-detection testing scores for McAfee, so its protection powers are unproven.

Firewall is a component of Avast Premium Security and Avast Omni, which creates rules each time an application or process starts for the first time. These rules determine how Firewall behaves toward each application or process when it connects to the internet or to another network. Although advanced users can manage these rules or create new ones, we recommend you only modify your Application Rules if absolutely necessary. In most cases, Firewall formulates optimal rules without your input.

Create a new application rule

Default rules are created automatically for applications from known and trusted sources the first time you start the application after Avast Premium Security or Avast Omni is installed. Application Rules are organized into groups, predefined according to application vendor. To add an application to an existing group:

1. Open the Avast user interface and go to Protection ▸ Firewall.
2. Click Application settings at the bottom of the screen.
3. Click New application rule and select a group (vendor).
4. Locate and select the executable file of the application you want to add.
5. Click the group name, then use the orange bars to indicate the level of access you want to allow.

To create a new group, click New Group and provide a name for the group.

Adjust access restrictions

You can set connection allowances for each application or process to determine how strictly Firewall monitors incoming or outgoing communication.

Click a group (or vendor name) in the Application column, then use the orange bars in the Allowed connections column to set the authorization level for a specific application:

Avast For Mac Blocking Internet Sharing

• One bar (Friends out): outgoing connections with Friends networks only.
• Two bars (Friends in/out): incoming and outgoing connections with Friends networks only.
• Three bars (Internet out): all outgoing connections to the internet.
• Four bars (Friends in and Internet out): incoming connections with Friends networks only, and all outgoing connections to the internet.
• Five bars: (All connections): all incoming and outgoing connections to the internet.
• To Block all connections for an application, hover your cursor over the orange bars and click the red block symbol that appears.

Set actions for unauthorized connections

In addition to defining the types of connections you authorize for applications or processes, you can also specify how Firewall behaves when it detects a non-authorized connection. To define Firewall behavior for a non-authorized connection:

1. Click a group (or vendor name) in the Application column to open the list of applications or processes in that group.
2. Select an application or process to expand its individual communication settings.
3. Use the drop-down menu to manage the program's behavior. The following behaviors are available:
   • Default rule: Firewall decides to allow or block connections based on the settings of the active Firewall Network profile (Private or Public).
   • Auto-decide: Firewall allows connections with verified applications, but blocks connections from unknown or suspicious applications.
   • Block: Firewall blocks all other connections.
   • Ask: Firewall asks you to decide if you want to allow or block a connection each time a new request is received. Selecting this option may result in frequent and potentially obtrusive alerts.

• Private: a lower level of security suitable for when your PC is connected to a trusted network such as your home or work network. This profile enables better connectivity, and permits all communication within the network.
• Public: a higher level of security suitable for when your PC is connected to a public network such as in a cafe or airport. Because public networks present greater security risks, no incoming communication is permitted when this profile is set.

Specify authorized ports

Tighten rule restrictions even further by specifying the network ports each application uses for communication when an incoming or ongoing connection is allowed. To specify authorized ports:

1. Click a group (or vendor name) in the Application column to open the list of applications or processes in that group.
2. Select an application or process to expand its individual communication settings.
3. Specify the Outbound ports and Inbound ports that you allow the application or process to communicate with. Specify ports in the following ways:
   1. Type specific port numbers into the text box. For multiple ports, separate each port number with a comma.
   2. Select All from the drop-down menu to authorize communication with all ports.
   3. Select a predefined port number from the drop-down menu.
4. Optionally, configure Packet rules from the Application rules screen by following steps 1-2 above, then clicking Packet rules. While Firewall uses Application Rules to control traffic according to individual rules for programs or services, Packet rules can also be configured to control network traffic using specified connection parameters. Packet rules enable you to view and manage Firewall rules according to the information contained in network packets, such as network protocols, source or destination IP addresses, or local and remote ports.
