I already know some programs can compare between two snapshots but they only work on my real machine but I want to know how to know the difference between two virtual machine snapshots
Example :
->Create new VirtualBox virtual machine
->Install windows
-> take snapshot (1)
->Execute a malware
->take snapshot (2)
now how can i know the new , the edited and the deleted files or registry keys or any other thing ( What the malware have done on the system ) ???
Please focus on how to know the file changes
