Malwarebytes is one of the best and absolutely free anti-malware tools. I discovered this tool back in 2014 when I had some virus on my computer and my antivirus couldn’t detect it. I will not mention here the names and brands of antivirus, but you should know that even their employees are using Malwarebytes to detect the most recent threats. Malwarebytes Anti-Malware is easy to install and configure, it also has a user friendly interface. Immediately after I installed it on my computer it detected and neutralized numerous threats that my anti-virus didn’t see. Anyway, few days ago I’ve updated my anti-virus and it asked me to reboot my computer, after reboot the Malwarebytes failed to start and gave me error saying that the program could not be launched, because the QtGui4.dll is missing, please reinstall.
First thing I tried is to reinstall the Malwarebytes software. After the installation was completed I started the program but the same error message appeared again. Well, from my experience, I can say that if I reinstalled the program and the problem remained, it means that the problem was not in the program. I started to google for various solutions and found a nice and easy guide about how to fix QtGui4.dll is missing errors in Malwarebytes.
To fix the QtGui4.dll is missing error in Malwarebytes you just need to download and install the missing file from here: http://fix4dll.com/qtgui4_dll.
Now you can start up your Malwarebytes and use it normally.
Remember, it is always important to keep your antivirus and anti-malware programs updated to the latest versions. You may find the latest version of Malwarebytes Anti-Malware for Windows here: https://www.malwarebytes.org .
