Developed to offer a multi-layered security level to PCs by cleaning and keeping at bay all forms of malware currently known.

Tips: In case you love having a backup on the go, this anti-malware can be carried on a USB and run it on USB. Take advantage of the highly flexible Command Line Interface (CLI). Web browsing feels really safe with real-time protection like this:

anti-malware for web browsing

Additionally, Malwarebytes defends against all kinds of online threats and takes one more step further by educating users about it. For example, it covers:

  • 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

Cons

  • Does not operate singly and needs reinforcement from antivirus software
  • Cannot be automatically scheduled to carry out malware scanning
  • Most of the features quickly expire prompting you to update to the paid version

Verdict: Malwarebytes effectively ‘bites off’ any popup ads that can easily spawn your computer. With this program, Potentially Unwanted Programs (PUPs) are instantly deleted and removed from the system. While running Malwarebytes, we didn’t notice any PUPs, it brings a professional feel to the way one uses their PC.

Malwarefox

OS: Windows (7 to 10) | Installer: 7MB | Trial: 15 days, Pro: $26.24/year | Money back guarantee: 30 days | Custom scan: yes | Country: USA

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 15-day free trial with a forced watermark.

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).

MalwareFox review

Tips. Malwarefox has some extra tools : 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

Verdict. Malwarefox is a lightweight antimalware software with a handy drag-n-drop area to check files/folders individually if needed which makes it easy in use., Also, it has program status tab – with license, system health, date of last scanning, date of last updates, etc, so it will be good for unexperienced users.

New antivirus product from Kaspersky Lab now comes with a module defending against malicious software, and it consumes less system resources thanks to rebuilt algorithms. You can manage devices in My Kaspersky account, which also provides access to password manager and parental control options.

Tips. Kaspersky Secure VPN can be safely removed if you don’t want to use it – it won’t key Kaspersky functionality.

Pros

  • Adblocker inside
  • Software updater
  • Low resource usage

Cons

  • Limited traffic in VPN
  • Poor customization options
  • Difficult menu in some parts

Verdict. Kaspersky Internet Security has definitely become better in recent years. However, it still needs more tools for protection and configuration options.

Developed to run a full scan upon prompting, Zemana works by detecting and storing file fingerprints on a cloud server after deleting them from your computer. This free anti-malware program uses negligible hard drive space and can be used together with other similar tools.

free anti-malware software

Tips. Drop specific files or folders (see main dashboard) for a deep scan. For best results, it should be used alongside another antivirus as an additional security tool. It has a built-in scheduler that one can program to run every time the PC is booted, daily, weekly or at set times.

Pros

  • Highly optimized and lightweight
  • Works without leaving any footprints on your PC
  • Quick and easy-to-install
  • Offers real-time protection

Cons

  • Does not have a free version, therefore, one needs to pay for annual usage for after the trial
  • It hadn't detected plenty of malware files as other tools had
  • Quite long scanning times

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.

HitmanPro

OS: Windows (XP to 10) | Trial: 30 days, Plus: $25/year | Money back guarantee: no | Custom scan: no | Country: USA

HitmanPro by Sophos offers a fast and targeted malware scanning, and it can run alongside other antivirus software. The US vendor also claims to be applying special “behavior-based techniques”, unlike virus signatures in typical tools, that help identify brand new malware files even if they seem innocent.

Pros

  • Signals in big red interface color if it detects threats
  • Save log feature
  • Database of threats plus cloud technology scanning

Cons

  • Only trial for 30-days free
  • Available only for Windows
  • Collects all PC performance issues rather than focusing on malware

VerdictHitmanPro is a small easy tool, that is effective in detecting and removing malicious software. In our test it found the biggest number of issues, even beyond malware/adware, e.g. old cookies, outdated drivers, trails of past programs, etc.

This kit is useful for scanning, detecting and cleaning harmful viruses, spyware, keyloggers, adware and other malware on your PC. Comes with a portable version, meaning it can be carried on a device like a USB drive. Has a relatively faster speed when compared to other anti-malware tools of the same scope.

best malware removal tools

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.

Verdict. Spybot Search & Destroy anti-malware did an above satisfactory job in identifying and fixing malware, spyware and adware on our system.

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.

free malware protection MSRT

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.

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

Tips. Can be used in combination with another tool for example Malwarebytes. If you find it difficult to find a quarantine in Avast, not they just call it Virus Chest. Or, another way to find scanning logs is to go this route (C:\ProgramData\AVAST Software\Avast\log) on your PC.

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.

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.

Cons

  • Unfriendly menu

Few more honorable mentions

1. 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.

2. 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.

  • All actions accessible in the main windows
  • Automatic database updates

Cons

  • Uninformative scanning, no pause option

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.

FAQ

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.
