VirtualBox Is Not Responding

Hi,

A couple of days ago, I installed VirtualBox to secure my network as I am working on project based on security and Python. What I noticed is that the slow speed of my Python platform which is impacting the project. Sometimes, I got notification as VirtualBox Is Not Responding. As per the Python tutorial blog, I found on Stackoverflow, I must check dependencies properly and change BIOS settings. I tried it but I didn’t find any irregularity in it.

So what could be the possible solution to fix it?

Thanks
