Can malware escape a virtual machine?

In terms of affecting the host memory directly, the virtual machine cannot, because it cannot see it.

What are the disadvantages of using a virtual machine?

Disadvantages: Virtual machines are less efficient than real machines because they access the hardware indirectly. Running software on top of the host operating system means that it will have to request access to the hardware from the host. That will slow the usability.

How do you stop a virtual machine from escaping?

To minimize vulnerability to VM escape, Skoudis recommends that you:Keep virtual machine software patched.Install only the resource-sharing features that you really need.Keep software installations to a minimum because each program brings its own vulnerabilities.

Can a virtual machine infect the host?

It is not impossible for malware to infect the host via a VM, for example via network shares, open ports in the firewall with vulnerable service running on the open ports, or via other security leaks in the configuration.
