“IMF.exe” is the primary executable of Malware Fighter by IObit Pty, Ltd., a Chinese company in Shanghai founded in 2004.

Problems may occur if Malware Fighter is installed when Malwarebytes Anti-Malware or Avast antivirus is already present. It can be uninstalled through the Control Panel’s “Uninstall a Program” applet by selecting “IObit Malware Fighter”; do so if a system startup error says “IMF.exe” cannot run because ”rtl120.bpl” is missing.

Some companies, including Malwarebytes, have questioned their ethics regarding intellectual property.

it seems to slow down my computer and does not seem to be beneficial to my computers over all operation. This is not typical in my experience for an Iobit program
its a simple anti virus from iobit

it uses a LOT of memory as a background bad-guy finder, but... if the real-time was so good, why do scans? -FFT-

It is not helpful to remove viruses and malwares. Slows down computer.
I don`t have the best PC and it let my pc crash because it needs to much ressources. If you have a bad PC like me I don`t think that you should let the software on your pc.
It is program for cleaning and that, tho takes some resources, you can execute it in task manager.
serious slowdown of internet! I am deleting it.

Best practices for resolving IMF issues

A clean and tidy computer is the key requirement for avoiding problems with IMF. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
