How to remove QtCore4.dll malware from system using Comodo Cleaning Essentials?

You can either choose to remove QtCore4.dll and other malwares using Comodo Antivirus, or Comodo Cleaning Essentials (CCE) – both of which are absolutely free to download! CCE is a set of computer security tools designed to help you identify and remove malwares and unsafe processes from an infected computer.

To remove malwares using CCE, take the following steps:

1. Check the system requirements and download the feature-rich CCE suite for free.
2. After installation, choose the type of scan you want to perform. CCE offers 3 scan options to get rid of malwares from a PC:
  • Smart Scan: Does a scan on critical areas of your system.
  • Full Scan: Does a complete scan of your system.
  • Custom Scan: Does a scan only on selected items.

The process to initiate the above mentioned scans are self-explanatory and thus, easy-to-use. 
Additionally, it's recommended that you approve of any updates that the CCE will prompt you about to ensure it does a better job of identifying all the latest threats.
