IObit Malware Fighterfor Windows


Free security software for Windows

IObit Malware Fighter is a free program designed to protect your Windows device from threats, including adware, ransomware, trojans, keyloggers, spyware, and hijackers. With added features, such as protection for your webmail and an adblocker, the app aims to provide comprehensive peace of mind.

Is IObit Malware Fighter an antivirus?

Yes. It has a lot more functionality beyond that, though. It also provides a security & privacy software package that aims to give you all-around web and device protection. 

In the paid version–IOBit Malware Fighter PRO, there’s also a password-protected safe box, where you can store your most sensitive files and add a second layer of protection from infections and ransomware.

How do I use IObit?

IOBit MF is a very simple program to use. During the download and installation process:

  • Once you’ve installed the program, next run the initial scan with default settings
  • To run a scan, just click the ‘Scan’ button and choose whether you want the Smart (quick), Full, or Custom scan


Why buy the paid version?

If you choose to buy IObit Malware Fighter PRO, you’ll benefit from enhanced antimalware and antivirus integrated with BitDefender’s engines, the password-protected safe box, protection from unknown programs accessing your camera, and automatic scans and updates. You’ll also receive technical support via email.

How do I uninstall IOBit MF?

You can uninstall it through the program list in the Windows Control Panel.

Our take

Even for a free app, IOBit Malware Fighter is incredibly basic. There’s nothing about it that differentiates it from many other free security packages. In fact, there are plenty of free options that provide much more robust protection. Big names such as Malwarebytes, Avast, and Windows Defender are other free options that you may wish to consider.

Should you download it?

No. There’s nothing compelling about IOBit MF to convince that it’s an essential download.
