  • Malware – malicious programs or codes that aim to invade and damage computers/devices, i.e. viruses, worms, trojans, cryptomining, keyloggers, rootkits, explouts, etc.
  • Ransomware – a type of malware that blocks users from system or personal files, demanding payment to regain access.
  • Spyware – malicious programs that infect a PC/phone to collect user information, browsing habits, etc., i.e. password stealers, banking trojans, keyloggers.
  • Adware – programs that aim to display ads on a screen or in a browser, a.k.a. PUPs – potentially unwanted programs.
  • Cryptojacking – a newly emerging threat, programs that hide on devices and use it to mine cryptocurrencies.
  • Phishing – the most direct and blatant form of hacking in form of deceiving users into sharing sensitive data, like passwords or credit card numbers. Malwarebytes Premium detects such suspicious sites and warns you from going there.

Pros: It detects and removes spyware, botnets, Trojan horses and other infections Very easy to use and has straightforward instructions that can be easily followed Enhances real-time protection against infection when used with antivirus

Verdict. Zemana utilizes few resources and yet conducts full scans. Since it was never developed to be the first line of defense this anti-malware is very effective to compliment other antivirus software. We think its helpful in the sense that it seamlessly works with our other antivirus tools and lives to fulfill their claims.

Tips. Users can take advantage of the custom scan feature to decide what or what not to remove, in case you’re a noob, you can opt for default scan settings that will automatically carry out a full scan according to the engine’s capabilities.

Pros: Very effective in destroying malware with a 90% success rate The monthly release of newer versions of Emsisoft ensures that it is not easy to modify or replicate it thereby making it more secure It is compatible with all Windows versions

Cons: Lesst useful against infections, rather effective as a counteractive tool against malware Not actually free - only 30-day trial available Requires to stop a running antivirus program May slow down the whole system

Verdict. We ran Emsisoft and initially had time to select the files and programs to be scanned. The scan engine works quietly in the background. Later, we shifted to manual selection – which still works but takes a lot of time and proved to be taxing. Thus, when using Emsisoft, it would be best to use manual side. The anti-malware scores highly in malware detection and cleaning out malware from a PC.

Overall, AVG not only protects your system but also covers internet activity, thus AVG detects various malware and ransomware in real-time.

Verdict. The effectiveness of AVG scans and repair coupled with the ease of use makes it a popular antivirus, as well as malware removal tool. Although, don’t forget this is a free version, and even with “Deep Scan” feature to find spyware, limitations apply. Overall, AVG is worth trying out for basic protection.

This is a malware protection tool developed for the Windows operating system and has been in operation since 2005. A new version is released monthly as an update. The tool must be used together with a trusted antivirus program as advised by the developers, Windows Defender Antivirus first of allUsing MSRT is most relevant when one turns off automatic updates for Windows, which would also runs the tool in the background.

Tips. Should best be used in conjunction with other antivirus tools because it does not stay running in the background and need to be manually started. The program automatically removes any active malicious software detected with just a click of the restart button.

Pros: Works to check for an extensive list of the different types of malware It is portable Can perform 3 types of scans

Cons: Cumbersome to use since the machine must be restarted in order to fix any detected malware Does not offer real-time protection since it does not stay running all the time

Verdict. It is effective for malware detection and cleaning up but cannot guarantee total protection if used alone – most effective if used together with another antivirus. This is a major concern though because one can never fully rely on Windows Malicious Software Removal Tool for a thorough job protecting their system. Hence, the program has a low rating/score based on failure to offer solid stand-alone protection in real time.

Verdict. Comodo provides users with a mature, full package. Quick basic scan took us about 10 minutes and found 1 threat, while full scan lasted over an hour and resulted in 55 threats. Overall, testing Comodo was fine because of its straightforwardness, advanced operation features. When looking for a serious and effective tool for malware detection and protection, Comodo free antivirus is sure set to deliver.

Avast is an antivirus designed to offer real-time protection against malware threats by scanning and detecting potential threats on your system.

Also, there is a brand new feature that has been added mid-2018 – Ransomware shield. Though, it is available now in Avast Premier and Avast Internet Security, it’s great in a way that it secures personal documents, photos, files from ransomware attacks. With it, users may specify which folders to protect specifically.

Pros: Scores highly in malware detection Easy-to-install and use, lightweight and easily optimized Compatible with most operating systems including Android for smartphones

Cons: Comes with many ads and pop-ups which can be distracting and time-consuming.

Verdict. Actually, Avast came with a host of security-related tools as well as handy utilities (which we found surprising since this was a free version on trial). At the end of the day, it was easy to understand that the ease of installation and usage, as well as the added real-time protection features, make Avast popular among basic users including gamers.

This antimalware app by Gridinsoft company runs on all popular versions of Windows OS, and is great to check for spyware, adware, PUPs, etc. The main drawback in its free version is that it only scans a computer – for removal functionality one has to pay.

Some sources claim that Total Defense works through the Bitdefender engine, though we haven’t noticed anything about it, good or bad, or whatever. The main thing in our case, is that in real-time protection mode 70% of test malware was blocked, while regular scanning reached 94%. The app stores detected signatures on a local disk, so it could act even without the Internet connection.

Total Defense antimalware software

Tips. Total Defense official website doesn’t offer a direct link to trial. Instead, as one signs up, they send a one-time link to email, so use a real address.

Pros: High detection rate PUA remover Affordable price

Few more honorable mentions

1. Malwarefox

It has both free and Premium version, the difference being that most of anti-malware features are available in the latter, e.g. real-time protection, set of anti-adware/anti-spyware/anti-rootkit utilities. Actually free version is a 14-day free trial with a forced watermark.

MalwareFox review

43 menu languages, well-designed and intuitive UI, but questionable color solutions and visible borders between screens. In terms of functionality, MalwareFox offers scanning, quarantine, removal and event logs/history. There is no ability to adjust scanning or select scan type, as it basically works in 1 mode which is a “quick scan”, which performs mediocre (5 out of 18 threats during testing).

On the other hand, there’s a handy drag-n-drop area to check files/folders individually if needed, plus program status tab – with license, system health, date of last scanning, date of last updates, etc. Extra tools include: a) exclusions – to uncheck certain files/folders as safe; b) auto launch at PC startup – to minimize risks (but there’s no password); c) automatic send off of unknown files for cloud scanning; d) sound alerts when threats are detected; e) detection of suspicious certificates (though unclear policy about the process).

Pros: Portable version available Quick and well-performing scan Easy to use, interface themes to choose

Cons: Database updates only manually No real-time protection mode Some features aren't fully implemented

Key features: Hijacker removal, Cloud scan, Browser cleanup.
Pricing: Free, Personal – 13.00$, Technician – 32.00$.

2. MalwareHunter

Utilizing Avira engine, it is a fine program to detect malware through 3 types of scans and to optimize a PC afterwards. Extensive database that is also being regularly updated. By and large, Malware Hunter suits best for personal use, with free and Pro versions, for those who want to insure against modern web threats and data leaks.

Scanning does not slow down the machine, displays stages, progress, files found, and can be stopped, paused or resumed. Reports section provides threat analysis after detection, with risk level, type, as well as search or export options.

Pros: Interactive scanning process, with many details Avira engine with high rate of signature detection Extra tools for PC optimization

Cons: No ability to inspect individual files and folders Scanning reports can’t be exported, only to view No proper technical support and manuals

Neat and compact interface is easy to operate, with features located on the left – scan, speed up, settings, clean up, etc. Extra tools available: CleanUp – to wipe the registry, plugins, random memory; SpeedUp – to analyze and improve startup files, running apps, system files, network, etc.

Key features: 3 Scan modes, Avira engine, Malware removal.
Pricing: Free, Pro- 24.97$.

3. Stronghold AntiMalware

A product with several atypical features and lots of settings to set up user protection against malware and malvertising. In case a browser gets heavy with ads, popups and suspicious activity, there’s “Browser settings reset” for example, which is somewhat extreme, as it resets all the browsers on a given PC at once.

For a lighter action, use “Toolbar removal” feature, that eliminates history, extensions, bookmarks for a selected browser. Active monitor feature is great if you want to exclude certain apps from active scanning. To decrease processor load, there’s “Hybrid cloud” option – to utilize cloud storage while scanning instead of PC resources.

On the other hand, anti-malware performance and efficiency is mediocre, as the program does not detect all threats, and in trial there’s no possibility to delete infections. Full and quick scan available, with the latter lasting about 10-15 minutes on average.

“Restore changes” allows to reverse the removal, but unclear about how it works or what it means. The Support tab will bring you to the website with FAQ and contact form. Trial version is free without time limit but with limited functionality.

Pros: Plenty of extra features Great technical support Free trial version for lifetime

Cons: Unable to remove malware in trial Average detection rate Frequent crashes

Key features: Toolbar removal, Scheduler, Activity monitor.
Pricing: License- 29.95$.

4. Secure Hunter

Installing from a .zip file, and then works by analyzing incoming files and running them by antivirus database. Overall, Secure Hunter is good for home or personal use, with both free and paid editions presented. It defends against spying programs, adware, trojans, rootkits, worms, keyboard spies, etc. by inspecting files, services, drivers, startup, MBR and archives on PC.

Secure Hunter review

The interface is somewhat overloaded and unorganized. Scanning offers three modes: “custom hunter”, “full system hunter”, “computer scan” aka quick scan. In process it only shows the number of processed files, detections and type, there’s no ability to pause it. Threats can be deleted or ignored, but not restored after deletion. For guidance and work issues, there’s a tab to send feedback to vendor.

Pros: Free version without limitations All actions accessible in the main windows Automatic database updates

Cons: Uninformative scanning, no pause option Clumsy and disorganized interface Many issues in performance

Key features: 3 Scan modes, Malware Removal, Ignore list.
Pricing: Free, Pro – 20.00$.

5. ByteFence

Quick scanning and browser inspection are the highlights of ByteFence, which is a typical malware removal niche product. As proved by testing, it can find threats that other programs couldn’t and general detection rate is above 90%.

ByteFence review

Otherwise, there’s a lot of room for improvements. Scheduler only has 2 modes: daily or weekly, which isn’t great. Gaming mode that turns off any external alerts provides very little information to a user. Browser control identifies suspicious homepages, analyzes plugins and add-ons, but does not clean and optimize to the full effect.

Pros: Free version without limitations All actions accessible in the main windows Automatic database updates

Cons: Uninformative scanning, no pause option Clumsy and disorganized interface Many issues in performance

Key features: Do not disturb mode, Whitelist, Antivirus.
Pricing: Free, 3-months – 29.95$, 1-year – 59.95$.

Test summary & comparison

For analysis and review of those best free anti malware software we used a typical user laptop: Acer Aspire with Windows 7 Professional 64-bit system, 3 GB RAM, under 3.5 MB/s Internet speed. We tested and measured the following aspects:

  • installation time
  • disk space on PC/device
  • full scan time
  • total files scanned
  • threats and/or issues detected

With each tool we ran a full scan to see what and how many issues it finds. Afterwards, we didn’t delete and malware, so we would be scanning the same system with same vulnerabilities and check how other anti-malware tools perform. Below is the final comparison of top ten free antimalware software performance.

Anti-malware software guide

Malware prevention measures

Any device that can access the internet is susceptible to malware infection. One should exercise caution while using the internet by the following:

  • Not opening suspicious email or links as this could lead to phishing and data harvesting, by cyber attackers;
  • Regularly updating the Windows operating system and other software;
  • Investing in strong antivirus programs;
  • Taking appropriate action on suspected threats as advised by an antivirus;
  • Using firewalls, a secure web browser;
  • Not installing unknown or illegally downloaded software.

Protecting your system from malware is vital in safeguarding your data. However, investing in a stable antivirus or antimalware tools is also important because often times malware will still find ways to infiltrate your system despite caution.

What is anti-malware?

A type of security software that guards PC/laptop/mobile device against malicious software, a.k.a. malware. It has two major tasks: to detect and prevent malware from infecting computers, and to find and remove malware if its already in the system. Often, anti-malware comes as a part of Internet security suites, along with anti-spam, safe browsing, parental control etc.

In recent years there has been a significant rise in types of malware (ransomware, spyware, adware, cryptojacking, rootkits, email phishing, viruses, etc.) as well as unlawful cyber-crime attacks. According to Statista, each year literally billions of malware attacks take place worldwide. Consequently, antimalware tools are in high demand.

Why or when should you use anti-malware?

Malware attacks and tricks are evolving all the time, and top security software applies various methods of detection and database of malicious signatures to identify threats in real-time. On enterprise level, with computer networks and valuable data, anti malware may be set to provide such protection, as well as track metrics and analytic tools for insights. On personal level, you might become a victim of hacked Facebook / Instagram account any given moment, potentially causing harm to reputation.

How is it different from antivirus?

Malware is short for malicious software. It is software designed by cyber criminals aimed at discreetly gaining unauthorized access to data stored in a network, server or computer. Cyber-criminals then use the data for their own gains or to destroy the recipient’s system or eliminate access to it.

To operate, malware is introduced into the target host in the form of codes, scripts, phishing emails, etc. Moreover, it can sit in USB sticks, as well as CDs, and starts on whenever the storage device is immersed into the target. Types of malware include:

One of the leading vendors of anti-malware gave a clear explanation, and if paraphrasing, a virus is a specific threat, and malware is a term encompassing a multitude of threats, therefore any virus is malware, but malware isn’t only viruses. In contrast to antivirus programs, anti-malware focuses on the newest threats on the web and is updating much more regularly. Antimalware programs help fight the following online threats:

  • Malware – malicious programs or codes that aim to invade and damage computers/devices, i.e. viruses, worms, trojans, cryptomining, keyloggers, rootkits, explouts, etc.
  • Ransomware – a type of malware that blocks users from system or personal files, demanding payment to regain access.
  • Spyware – malicious programs that infect a PC/phone to collect user information, browsing habits, etc., i.e. password stealers, banking trojans, keyloggers.
  • Adware – programs that aim to display ads on a screen or in a browser, a.k.a. PUPs – potentially unwanted programs.
  • Cryptojacking – a newly emerging threat, programs that hide on devices and use it to mine cryptocurrencies.
  • Phishing – the most direct and blatant form of hacking in form of deceiving users into sharing sensitive data, like passwords or credit card numbers. Malwarebytes Premium detects such suspicious sites and warns you from going there.
  • Botnets – intended to corrupt a network of machines globally or in an intended target organisation to perform a number of functions such as steal data or block certain keywords/articles/content from being visible on search engines.
  • Wiper malware – intended to delete or completely wipe out the intended target’s sensitive data so that the user cannot gain access.
  • Other malware/scripts include computer worms, scareware, cryptocurrency mining malware and computer viruses.

Types / Features

As we’ve mentioned, each anti-malware applies different detection strategy, or a combination, to protect against damaging code. So, we may divide them in 3 types:

  • Signature-based, such as Emsisoft Anti-Malware Home or McAfee.
  • Behavior-based, such as Malwarebytes or HitmanPro.
  • Sandbox, such as Cuckoo Sandbox, Shade or FortiSandbox.

Each type has peculiarities in user interface, system requirements, malware removal options, that should be in mind of a conscious customer.

By business model, there could be a distinction between all-in-one internet security suites and specialized programs. Avast, AVG, Kaspersky and so forth are good examples of security suite, where certain anti-malware tools are part of bigger integrated system. Malwarebytes, Malware Killer, Cybereason and others are software specifically designed to prevent malware and nothing more.

Which type is more relevant is still a subject of discussion. At the same time, general malware prevention measures while browsing the Internet include the following:

  • Not opening suspicious email or links as this could lead to phishing and data harvesting, by cyber attackers;
  • Regularly updating the Windows operating system and other software;
  • Investing in strong antivirus programs;
  • Taking appropriate action on suspected threats as advised by an antivirus;
  • Using firewalls, a secure web browser;
  • Not installing unknown or illegally downloaded software.


Malware, PUA/PUP, malicious scripts are on the rise, evolving constantly. In 2018, evasive malware and exploit kits emerged as one of the ways to pass through security software, for instance ransomware such as Cryptomix, Spora, TeslaCrypt, JigSaw. More and more attackers use malicious cryptomining, running hidden scripts on users’ devices without permission, basically hijacking resources, electricity, etc.

For anti-malware tools the upcoming years will be a busy time. Digital security suites are investing more money and introducing new techniques to protect computers, smartphones, networks, servers, IoT devices. New methods such as so called “vaccinations” against malware families (misleading malware to think it is already in the system), and others will have to up the game.

Malwarebytes Labs predicts the following challenges for 2019: high-profile password breaches, AI-assisted malware, self-propagating exploits like EternalBlue to spread infections, more attacks on Microsoft Edge browser, skimming – i.e. hijacking checkout pages and intercepting payment information.


Q: What is anti-malware software?
A: Anti-malware (a.k.a. Antimalware, anti malware, malware removal software, malware scanner tools) are special software programs that detect and remove malware from computer devices. Anti-malware protects against malicious scripts, viruses, rootkits, ransomware, spyware, adware.

Q: How does anti malware work?
A: To prevent malware, this special type of security software implies three main methods: signature-based malware detection (see the 2nd paragraph above), behavior-based detection (by intentions, behaviors, actions, etc.) and sandboxing - testing stuff in virtual environment before allowing it into the system. By design, anti-malware can do the following tasks: block suspicious websites, quarantine the detected malware, display data about the infections and insights into how and how far a malicious script has compromised a network.

Q: What is the best anti-malware?
A: You can’t go wrong with Malwarebytes, HitmanPro, Emsisoft, Comodo, Zemana, AVG/Avast. For more considerations, pros and cons, tips and more read our product reviews, sich as Malwarebytes, Malware Fighter, Spybot, etc.

Q: Is anti-malware and antivirus the same thing?
A: No, but similar. A virus is also a malware, but malware isn’t necessarily a virus. Thus, an antivirus software protects against computer viruses specifically, while antimalware covers a wider range of threats: trojans, worms, unwanted apps, ransomware, cryptomining, adware, exploits, keylogging, etc. Many antivirus programs have been expanding their functionality to defend against malware too. The best practice is to use both.

Q: What is Malwarebytes anti-exploit?
A: Anti-Exploit is a security program that was bought out by malwarebytes from ZeroVulnerabilityLabs, and is now in beta-version, as of January 2019. It runs in the background and specifically targets zero-day exploits in browsers, rootkits, phishing scams, malicious links and sites. It is only available in Premium package.

Q: What is Bytefence? Is it good?
A: Firstly, this is just one of the anti-malware programs and a popular antivirus. Secondly, it got (in)famous due to often being distributed in a bundle with another software which essentially means PUA. So it’s kind of “fight-crime-with-crime” situation. Many users online recommend removing it because it got them more malware instead of preventing it. We can neither confirm or disprove any information until we’ve tested it ourselves, so caution is our tip right now.

Q: How to choose the right antimalware program?
A: Go with reliable and reputable. Seek programs that can protect itself against termination by another software, that won’t cause conflicts with antivirus, that can automate scanning and is always up-to-date. A good anti-malware is often an “all-inclusive” package/suite - with security scanning, parental control, password manager, web protection, backup and restore, firewall, etc. It should not affect PC boot time and overall performance, be easy to navigate, fast in scanning, provide full control over all elements.
