Avast Antivirus provides a range of scans to protect your PC from malware. You can also create your own scan and specify the parameters. Refer to the sections in this article for details about the following Virus Scans:
- Smart Scan: a comprehensive scan that detects malware, out-of-date software, browser add-ons with poor reputations, network threats, and performance issues.
- Full Virus Scan: a predefined, in-depth scan of your system that checks your storage drives and memory for malware (including rootkits).
- Targeted Scan: scans the folders you select when you initiate the scan.
- Boot-Time Scan: scans your PC during the next system startup before any malware is launched. Running a Boot-Time Scan during startup improves the chances of detecting and removing malware before it can attack your PC.

- Explorer Scan: scans specific files or folders directly from your desktop via File Explorer.

- Frequency: define how often your scan runs.
Advanced settings
- Sensitivity (Medium by default): the higher the sensitivity, the higher the protection and potential for false positive malware detection. Lower sentivity reduces the potential for false positive detections, but may reduce the effectiveness of the scan.
- Scan for potentially unwanted programs (PUPs): enables Avast to scan for programs that are stealthily downloaded with other programs and typically perform unwanted activity.
- Follow links during scan: enables Avast to scan other files used by the files being scanned for potentially harmful content.
- Test whole files: enables Avast to scan entire files rather than only the parts typically affected by malicious code.
- Scan priority: use the drop-down menu to set your Scan priority (Medium priority by default).
Scan areas
- All Harddisks: enables Avast to scan all hard drives on your PC.
- System drive: the options in this section apply to data that is stored on physical devices such as hard drives and USB sticks.
- All Removable media: enables Avast to scan applications that launch automatically when you insert a USB or other removable device into your PC. Scanning removable media may take a long time due to speed limitations.
- Rootkits: enables Avast to scan for hidden threats in the system.
- CD-ROM & DVD drives: enables Avast to scan CD and DVD drives for malicious content.
- Modules loaded in memory: enables Avast to scan applications and processes that launch after system startup or run in the background.
Packers and Archives
- Scan most common used types: archive commonly used file types such as .zip, .rar, and other executable or installer archives.
- Scan all types of archives: the scan analyzes all archive files, which significantly increases the scan duration.
- Don't scan archives: disables Full Virus Scan from scanning archive files.
File Types
- Content based types (slow): scans files that are typically most vulnerable to malware attacks.
- Name extension based types (fast): scans files with only risky extensions, such as .exe, .com, .bat.
- Scan all files (very slow): scans all files on your PC for malware.

- Shut down computer after scan finishes: enables Avast to shut down your PC after your scan completes.
- Generate report file: enables Avast to create and store a report file automatically after the scan completes.
- Exceptions: click View exceptions, click Add Exception, then locate a file, folder, or web page that will not be scanned by your new custom scan.
Parameters for new Custom scans will save automatically and can be reconfigured at any time. To run a new Custom scan, go to Protection ▸ Virus Scans ▸ Custom scans, then click Scan Now next to the scan you want to run.
Process scan results
After a scan completes, Avast displays all found issues. You can resolve the issues directly on the results screen, or configure each Virus Scan to resolve issues automatically upon detection.
Smart Scan
To learn more about resolving found issues after Smart Scan completes, refer to the following article:
Other Virus Scans
You can define how each scan automatically reacts to a found issue.
- Open the Avast user interface and go to
☰Menu ▸ Settings. - Click Protection in the left panel, and ensure Virus Scans is selected.
- Click the scan you want to define automatic behavior for.
- Scroll down, tick the box next to Perform automatic actions during this scan, then select which action you want Avast to perform when an issue is found. The following actions are available:
- Fix automatically: Avast attempts to repair the file. If unsuccessful, the file is moved to the Virus Chest. If that fails, Avast deletes the file.
- Move file to Virus Chest: Avast sends the file directly to the Virus Chest where the file cannot harm your system.
- Delete file: Avast permanently removes the file from your PC.
If you want Avast to do nothing when an infected file is found, untick the box next to Perform automatic actions during this scan (not recommended). To manage unresolved scan detections at any time, go to Protection ▸ Virus Scans ▸ Scan history.
Special cases
For incomplete scans, an error message indicating the reason the scan was unable to complete is visible on the scanning screen. Although there are many different reasons a scan may be unable to complete, some of the most common reasons are:
- Archive is password protected: indicates that the file is password protected. Some programs use password protected archives to store their data even if you did not set the password. Depending on your scan settings, only the 'wrapper' file is scanned while the archive content is not.
- Archive is corrupted: indicates that the file may be corrupt because it was only partially downloaded or saved to your harddisk, or that it is a special type of archive.
- The process cannot access the file because of another process: indicates that another process or program was accessing the file during the scan.
- The file is a decompression bomb: indicates that the file was too large to be decompressed for malware analysis. Decompression of large files generates vast amounts of data which can cause your system to be unstable or cause it to crash.
Adjust scan settings
Although customizable settings are available for some Virus Scans, we recommend you only modify settings for Custom scans. To configure scan settings:
- Open the Avast user interface and go to Protection ▸ Virus Scans.
- Click Settings (the gear icon) in the top-right corner of the Virus Scans screen.
- Select the scan you want to adjust settings for.
- Configure your preferred settings.
For more information about Virus Scan settings, refer to the following article:
Create and use Rescue Disk
If you suspect your PC is infected with malware and all other Virus Scans (including the Boot-Time scan) were unable to resolve the issue, you can use Rescue Disk. Rescue Disk enables you to scan your PC when your system is not running. This method significantly increases your chances of detecting and removing malware because the malware is detected before it is able to counteract.
For more information about Rescue Disk, refer to the following article:
Review scan history
To review scan history:
- Open the Avast user interface and go to Protection ▸ Virus Scans.
- Click Scan history.
- Hover your cursor over a scan panel, then click the down arrow to see the scan details.
Click the red X in the top-left corner to return to the main Virus Scans screen.

Today's best Avira Free Antivirus for Mac deals
The abundance of solid free antivirus solutions available on the Mac means you can be choosy about which one you download. For example, while we can appreciate Avira Free Antivirus for Mac for its relatively low impact during passive scanning when it's running in the background, that's not enough.
Unfortunately, while Avira's malware-detection score is good, it's not enough to make it the best antivirus for Macs. For Mac protection without any expense, we recommend Avast Free Mac Security; if you can afford $40 per year, then Kaspersky Internet Security for Mac is an even better bet for its perfect detection rates and parental controls.

Costs and What's Covered
As its name declares, Avira Free Antivirus comes without any price tag. For those who may want technical support and other perks, Avira also offers Avira Antivirus Pro ($44.95 per year), which bundles in software for both Mac and Windows, and the Avira Prime ($9.99 per month) subscription, which gives you access to all of Avira's paid products.
Avira Free Antivirus for Mac supports the most recent two editions of macOS, which at the time of this writing were macOS 10.12 Sierra and OS X 10.11 El Capitan.
Antivirus Protection
Avira protects Macs using traditional signature-based malware scanning, as well as behavioral monitoring that scans for patterns commonly seen in dangerous and unwanted files.
I'll go ahead and enable the secure connection scanning. But I scanned on both ends, Mac OS and Windows and now it's nowhere to be found so I guess I'm good to go but now there's one issue and it's not related to Win32:Malware-gen. In answer to your question, you would have a single Windows anti-virus package installed in the Windows partition, and a single Mac anti-virus package installed on the Mac partition. You could have each scan both partitions. MacBook Pro mid 2012 running HighSierra OS 10.13.3 and Boot Camp partition windows 10 - Avast Mac Antivirus has detected infections on the BootCamp volume everytime I scan and quarantine or delete the viruses they are detected again repeatedly and a new infection type and name is found. Today guys, I am going to be showing you how to create a windows partition (the right way) on your Mac. Please keeep in mind that you must be running Leopard or Snow Leopard (10.5.X or 10.6.X). Avast for mac found zhelan-gen2 on windows partition. Avast Pro Antivirus 2016 combines world-trusted antivirus and anti-malware protection, with additional features for those who aren’t afraid to get more technical.
Like most other antivirus products, Avira Free Antivirus for Mac constantly updates its malware-signature database, which receives information from the 100 million users of the company's Windows, Android and Mac software. Avira stops PC malware on Macs from spreading across external drives and networks.

In addition to routine background scans, Avira offers both on-demand and scheduled scans, and scans unopened archive files such as ZIPs.
Antivirus Performance
Austria's AV-Comparatives evaluation lab tested Avira's malware-detection skills and found it offered high, but not perfect, protection.
In AV Comparatives' July 2017 studies, Avira Free Antivirus for Mac detected 99.1 percent of malware, which translates to catching 681 pieces of malware and failing to detect six. In comparison, Avast Free Mac Security and AVG AntiVirus for Mac caught 99.9 percent of malware (686 out of 687).
Among paid options, Bitdefender Antivirus for Mac and Kaspersky Internet Security for Mac, detected 100 percent of both Mac and Windows malware.
Security and Privacy Features
As is often the case with free antivirus solutions, Avira Free Antivirus for Mac is light on extras. Although it comes with a firewall (disabled by default), macOS has its own already. A USB scanner tool can be added on by upgrading to Avira Pro.
While Avira does offer its SafeSearch Plus tool (free) to help you stay away from infected sites, it doesn't install the browser plugin during installation.
Performance and System Impact
Avira Free Antivirus for Mac had a mixed impact on system performance. We assessed the performance hit with our custom OpenOffice benchmark test, which matches 20,000 names and 20,000 addresses on a spreadsheet and measures how long it takes to finish the task. Our test machine was a Late 2013 MacBook Pro with Retina Display, with a 2.6-GHz Core i7 CPU, 8GB RAM and 70GB of data stored on a 512GB SSD.
After we installed Avira Free Antivirus for Mac on our MacBook, the OpenOffice test finished in an average of 2 minutes and 24 seconds, 1.5 seconds longer than the same system took before installation. That's a passive system hit of 1.1 percent, on the lower end of the range we found among the eight products we reviewed.

During a full-system scan, the OpenOffice test finished in 2 minutes and 41 seconds, signifying a performance dip of 18.25 percent, the highest we saw. AVG's 12.1 percent was the second highest we recorded, and Kaspersky's 4.5 percent the lowest.

During Avira's quick scans, the OpenOffice test finished in 2 minutes and 37 seconds, which indicates a system slowdown of 10 percent. That's on the high end.

Avira Free Antivirus for Mac's full scans completed in an average of 30 minutes and 13 seconds, which falls in the middle of the times we recorded. By contrast, the longest time we saw was 72:45 (Kaspersky), while the shortest was 1:25 ( Bitdefender). The average for all eight Mac antivirus products tested was 36:30.
Interface
Avira Free Antivirus for Mac offers the same clean, modern look you see in many third-party Mac apps. Its main window presents a system status (Protected, typically) along with buttons for starting scans, scheduling scans, your quarantine, system activity and your license (more on that later).
Clicking New Scan gives you the option for a Quick scan or a full system scan, as well as a button to start the scan. While we prefer one-click scans, this arrangement is pretty decent and consolidates the screens into a pop-up menu.
The scheduled-scan page brings a drop-down sheet where you can name the days and times scans should run as well as their type (full, quick) and frequency (weekly, daily).
The Quarantine button brings you to a view of any files Avira has flagged as dangerous and set aside, while the Activity button shows you a list of your most recent scans. Clicking License lets you enter the Activation Code that an Avira Pro or Avira Prime membership comes with.
Clicking the option-toggles icon in the menu bar brings you to the Real-Time Protection screen, which allows you to disable file protection (don't do it) and enable Avira's Firewall. The profile icon brings you to what I'd call the About screen. Here you can see version info and click links to the Avira Community support page, product videos and other meta-level web pages.
Installation and Support
After you click Download, the superlight disk image file containing Avira Free Antivirus' installer will download. After opening that, the rest of the files are downloaded. In total, it took less than 3 minutes to complete the process.
Avira's customer support is limited to its paid customers, so you'll need Avira Pro or Avira Prime for that. In lieu of that, you can search Avira's FAQ documents and community message boards.
Bottom Line
Avast Mac Download
Avira Free Antivirus For Mac continues to be a good option for protecting your Mac from malware; unfortunately, that's not enough. Sure, we like its easy-to-use interface, but its malware protection scores aren’t as good as what AVG Antivirus for Mac and Avast Free Mac Security offer. Avast also causes less system impact than Avira, which makes it our top free choice.
