Why am I uninstall Other Antivirus softwires?

Hello A. 
Thank you for contacting AVG Support Community. 
We will certainly check and help you. 
We would like to clarify that AVG Antivirus will protect your PC against all types of malware. It includes Ransomware Protection too. If you have more than 1 Antivirus on your PC, both Antivirus may conflict with each and it may end up with incorrect threat detection. 
If both Antivirus works fine together then you can keep the other Antivirus. 
If you have any other queries, please feel free to contact us back, we are here to help you. 
Thank you.
