I am using Windows 10 Home edition (Fall creators update), 750 GB HDD. I use Oracle VirtualBox, and I have two virtual machines there: Windows 7 (32 bit) and Ubuntu 14.04.5. I will do malware-analysis inside the virtual machines. I will run malwares and analyze them. The malwares can be worm, trojan, virus etc.
Is it possible to keep my host (Windows 10) completely safe from the malware-infected virtual machines? If yes, how to do that?
If my infected virtual machines use the same wifi connection as my host, is there any chance for my host to get infected?
