Some run as the main operating system on the hardware, while others run on a pre-existing operating system. The most common is probably VMware ESXi, but Microsoft has Hyper-V, and there are a bunch of others. There are many different hypervisors available. They have no direct access to your base operating system, nor can they see any of the other virtual systems you're running. This gives you the capability of allocating resources to each of the different operating systems, giving one of them four CPUs and a couple gigabytes of RAM, while allocating eight CPUs and four gigabytes of RAM to a second system, for example. You install what's called a hypervisor on your physical computer, and then install different virtual machines, each with their own operating system, within that hypervisor. Virtualization, for those who may not be familiar with the term, is a way to abstract the hardware layer so that you can run multiple computers on a single piece of hardware.

Best of all, the solution is completely free! I'll walk you through the entire process. Unfortunately, all it takes is one slip to compromise your system, so you might want to employ a better solution: A virtualized, or sandboxed, browser environment. So how do you protect yourself? The first line of defense is make sure you keep your systems patched - update the operating system whenever new patches are released, keep your browsers and other software up to date, and don't visit unknown sites. There's also concerns around " malvertising," or malware that is embedded in advertising on websites, in addition to potentially malicious software you download and install yourself. It's also true that one of the easiest, and most successful attacks is from phishing, where the attacker sends an email with a malicious link, you click on it, and your computer automatically downloads and executes code that takes over your machine. If it seems like security is in the news on a daily basis, that's because it's is.
