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.

Regardless of the type of scan you choose, the results will sometimes show false positive (flagging files that are actually safe), which has to be ignored. Only select the files you want to get rid of.
