Real-time protection Blocks cyberthreats before they take hold. Frequently Asked Questions. How do I download and install the application? Because Chromebooks are devices with enabled features to access software and the web, an antivirus is crucial for every Chromebook. Even though Chromebooks are among the most secure devices, having supplementary antivirus software for security is not a bad idea. Fake browser extensions, harmful websites, phishing and other malware can all put Chromebooks at risk.

As a result, any antivirus for this OS must secure the device, scan for malware, regularly update and remove malware. Avast is one of the best-secured antiviruses that protects operating systems like macOS, Windows and even Chromebook.

Avast antivirus is a Czech multinational cybersecurity program developed by Eduard Kuera and Pavel Baudi in Some of the advantages of Avast antivirus are effective password management for hacker defense, speedier connections and WiFi inspections.

The first step to using Avast antivirus with Chromebook is to register an account on the Avast website. Then, download the relevant package for the device receiving the software. Launch the application after download and installation and then select the scan option. To scan the computer, click the start button next to the quick scan option.

Avast is a simple-to-use program with automatic updates. Avast is designed for easy security with all of the main features of antivirus software.

Avast provides users with a free version, premium security and ultimate security. These prices, however, are only valid for the first year. This antivirus may be used by anyone with a web browser and a variety of operating systems, including Android, Windows and Chromebooks, for optimal malware protection.

The software ranks among the lightest antiviruses for PC thanks to a single perfect 6. The lowest score was Malwarebytes is a Chromebook antivirus that employs specially developed malware technologies to detect, remove and target adware, spyware, potentially unwanted programs PUPs and browser hijackers.

Marcin Kleczynski created Malwarebytes antivirus to make the internet a malware-free zone. Malwarebytes for Chromebook protects Chromebook users by fighting scams, safeguarding personal information and screening for malware.

Malwarebytes also features four layers of protection that keep browsers and software packages safe from infection. Malwarebytes scans for viruses quickly, deletes all signs of infection and blocks the most recent threats. Before attempting to download, make sure that all open programs on the computer are closed. Then, to get MalwareBytes for the device, click the Download Free option.

For both the download and installation procedures, follow the prompts. If the computer prompts for permission to make modifications, choose Yes. Then, finish the installation process. After the program opens, select scan to begin the first scan. This may take several minutes. Malwarebytes is a low-cost and trustworthy portable scanning and real-time protection solution. Malwarebytes effectively removes any malware the program detects and features a basic user interface. Malwarebytes offers subscription plans for both personal and business use.

In the most current AV-tests, Malwarebytes Premium got 4. Avira Free Antivirus for Chromebooks is one of the best free antiviruses for Chromebooks with built-in ransomware protection. Tjark Auerbach, a German developer, created the antivirus software Avira Antivirus. Avira antivirus analyzes local files and even external devices for infection. This German antivirus, like the premium versions of some competitors, is quite effective. Avira offers all features for free and adds an extra layer of security by requiring users to protect apps with a PIN.

Avira also adds privacy permissions for system optimizer and VPN monitor apps. A rootkit is malware that provides the attacker with administrator privileges on the infected system and actively hides from the normal computer user. Rootkits also hide from other software on the system—even from the operating system itself.

Malicious cryptomining , also sometimes called drive-by mining or cryptojacking , is an increasingly prevalent form of malware or browser-based attack that is delivered through multiple attack methods, including malspam, drive-by downloads, and rogue apps and extensions. So instead of letting you cash in on your computer's horsepower, the cryptominers send the collected coins into their own account—not yours. So, essentially, a malicious cryptominer is stealing your device's resources to make money.

Exploits are a type of threat that takes advantage of bugs and vulnerabilities in a system in order to allow the exploit's creator to deliver malware. One of the most common exploits is the SQL injection. Malvertising is an attack that uses malicious ads on mostly legitimate websites to deliver malware.

You needn't even click on the ad to be affected—the accompanying malware can install itself simply by loading and viewing the page in your browser. All you have to do is visit a good site on the wrong day.

Spoofing occurs when a threat pretends to be something it's not in order to deceive victims to take some sort of action like opening an infected email attachment or entering their username and password on a malicious site spoofed or faked to look like a legitimate site. Phishing is a type of attack aimed at getting your login credentials, credit card numbers, and any other information the attackers find valuable. Phishing attacks often involve some form of spoofing, usually an email designed to look like it's coming from an individual or organization you trust.

Many data breaches start with a phishing attack. The old school method of signature-based threat detection is effective to a degree, but modern anti-malware also detects threats using newer methods that look for malicious behavior. To put it another way, signature-based detection is a bit like looking for a criminal's fingerprints. It's a great way to identify a threat, but only if you know what their fingerprints look like.

Modern anti-malware takes detection a step further so it can identify threats it has never seen before. By analyzing a program's structure and behavior, it can detect suspicious activity. Keeping with the analogy, it's a bit like noticing that one person always hangs out in the same places as known criminals and has a lock pick in his pocket. This newer, more effective cybersecurity technology is called heuristic analysis.

Each time a heuristic anti-malware program scans an executable file , it scrutinizes the program's overall structure, programming logic, and data. All the while, it looks for things like unusual instructions or junk code.

In this way, it assesses the likelihood that the program contains malware. What's more, a big plus for heuristics is its ability to detect malware in files and boot records before the malware has a chance to run and infect your computer. In other words, heuristics-enabled anti-malware is proactive, not reactive. Some anti-malware products can also run the suspected malware in a sandbox, which is a controlled environment in which the security software can determine whether a program is safe to deploy or not.

Running malware in a sandbox lets the anti-malware look at what the software does, the actions it performs, and whether it tries to hide itself or compromise your computer. Another way heuristic analytics helps keep users safe is by analyzing web page characteristics in order to identify risky sites that might contain exploits.

If it recognizes something fishy, it blocks the site. In brief, signature-based anti-malware is like a bouncer at the nightclub door, carrying a thick book of mug shots and booting anyone that matches.

Heuristic analysis is the bouncer who looks for suspicious behavior, pats people down, and sends home the ones carrying a weapon. Two relatively new forms of malware have helped drive the advancement of signature-less detection methods: exploits and ransomware. Though these threats are similar to others in many ways, they can be much harder to detect. Furthermore, once your computer is infected, these threats can be almost impossible to remove. Exploits get their name because they literally exploit vulnerabilities in a system, software, or web browser in order to install malicious code in a variety of ways.

Anti-exploit measures were developed as a shield against this method of attack, protecting against Flash exploits and browser weaknesses, including new exploits that have not been identified or vulnerabilities for which patches have not yet been created. Ransomware emerged on the malware scene to spectacular effect in Ransomware made a name for itself by hijacking and encrypting computer data, and then extorting payments as it held the data hostage.

Originally, both these threats resulted in the development of dedicated anti-exploit and anti-ransomware products. In December , Malwarebytes folded anti-exploit and malicious website antivirus protection into the premium version of Malwarebytes for Windows. We have since added anti-ransomware for even more advanced anti-malware protection.

Artificial intelligence AI and machine learning ML are the latest stars in the top antivirus and anti-malware technology. AI allows machines to perform tasks for which they are not specifically pre-programmed. AI does not blindly execute a limited set of commands. ML is programming that's capable of recognizing patterns in new data, then classifying the data in ways that teach the machine how to learn. Put another way, AI focuses on building smart machines, while ML uses algorithms that allow the machines to learn from experience.

Both these technologies are a perfect fit for cybersecurity, especially since the number and variety of threats coming in every day are too overwhelming for signature-based methods or other manual measures.

Both AI and ML are still in developmental phases, but they hold immense promise. If you find yourself in trouble, the go-to disinfectant for many is Malwarebytes. To get the antivirus company's free antivirus version, download this trial version , which "downgrades" to a no-fee on-demand cleaner with fewer features that detects and removes viruses and malware when you run an on-demand antivirus scan after 14 days.

In addition to the four antivirus apps we recommend above, a handful of other anti-malware tools are worth considering among the best antivirus protection if you find them at a better price or just prefer to use one over our picks above. It feels like McAfee Antivirus has been around forever, first on its own in the '80s, then as part of Intel starting in , and then again on its own when Intel spun it off in And McAfee Total Protection has been around forever because quarter after quarter it creates solid, modern antivirus software that protects your PC.

In recent evaluations by AV-Test, it had high scores on both protection and performance. Maybe this antivirus provider is not as well known to consumers because of its focus on enterprise security, Trend Micro antivirus quietly brings its business expertise to the home with its Trend Micro Maximum Security tools. Trend Micro's software earns high marks from AV-Test -- consistently scoring well for detecting zero-day attacks and widespread viruses and malware.

And Trend Micro does a good job of not taxing system resources. Free version? It earns high scores for usability and offers solid virus protection. The free antivirus version of Sophos Home gives you virus protection for three Windows PCs -- using the company's high-scoring anti-malware tool -- plus a day trial of the company's malware-removal tool. Test after test, Avast Antivirus for Windows performs well for malware detection with options ranging from Avast free antivirus software to Avast Premium Security.

And we've included its antivirus in our list of recommended security app options before. But Avast was in the news for several months for its non-antivirus business, so we looked at the company, specifically reports at the end of that Avast allegedly collected user data with its browser plug-ins and antivirus software and then sold data it collected through its Jumpshot subsidiary in early In response to the reports that his company gathered and sold the details of its customers' online activities, Avast CEO Ondrej Vlcek said in a statement that he understood that his company's actions raised questions of trust in his company.

To address that, Avast terminated Jumpshot data collection in January and closed its operations because the data collection business wasn't in line with Avast's privacy priorities. These newer reports follow another in from Avast that its internal network was breached , possibly to insert malware into its CCleaner software, similar to an earlier CCleaner hack that occurred prior to Avast's acquiring the Windows utility.

Avast is now saying the right things about taking its customers' privacy seriously , but it only came to that point after reacting to investigative reporting that revealed the Jumpshot practices. The CCleaner revelations, while concerning, were self-disclosed, which is important to building user trust.

We hope Avast's more privacy-friendly policies mean that there will be no further Jumpshot-style activities and it returns to glory as one of the best antivirus software. In the meantime, we'd recommend using one of the many other solid choices in this realm listed above.

Because the company has been in the news the past few years, let's talk about Kaspersky Lab -- specifically about the federal ban that blocks US government agencies from using Kaspersky Antivirus products. Based in Moscow, Kaspersky Lab has for years produced some of the best antivirus software for business antivirus needs and home customers. But in the US government prohibited Kaspersky security cloud software on federal government computers because of alleged ties between Kaspersky and the Russian government.

But as with China-based Huawei , the question remains: If the federal government doesn't think the products are safe enough for its own devices, should consumers avoid them as well? In a statement sent to CNET, the company said, "Kaspersky Lab has no ties to any government, and the company has never, nor will ever, engage in cyber offensive activities. Kaspersky Lab maintains that no public evidence of any wrongdoing has been presented by the US government, and that the US government's actions against Kaspersky Lab were unconstitutional.

In Kaspersky's favor, it continues to earn top scores and awards for virus and malware detection and endpoint protection from independent testing labs. And it's reasonably priced. In the end, even though no one has ever publicly produced a "smoking gun" linking the company to Russian intrigue, we think any of the options listed above are a safer bet.

And if you are a US government employee or work with the federal government, you'll want to steer clear of Kaspersky internet security products -- and perhaps use one of the antivirus software products mentioned here instead.
