1. A method comprising: intercepting, on a client device, a request to open unverified content; determining, by an application resolver without user intervention, that the unverified content is designated for opening in a disposable environment; causing the unverified content to be uploaded to a cloud file storage; causing a virtualization server to: provision a temporary virtual machine in the disposable environment; download the unverified content to a storage allocated to the temporary virtual machine; and open the downloaded unverified content using the storage allocated to the temporary virtual machine; receiving, by the client device and from the virtualization server, a confirmation that the temporary virtual machine is ready to connect; launching, on the client device, a client agent configured to communicate via a remote presentation protocol with the temporary virtual machine; connecting, by the client agent, to the temporary virtual machine in the disposable environment; displaying, by the client agent and on the client device, an output resulting from the opening of the unverified content using the storage allocated to the temporary virtual machine; responsive to a determination that the unverified content is benign: receiving, by the client device, display configuration information associated with the opened unverified content at the temporary virtual machine, wherein the display configuration information indicates a currently displayed portion of the unverified content; downloading, by the client device, the unverified content; opening the unverified content at the client device; modifying a display configuration of the opened unverified content at the client device using the received display configuration information to display the currently displayed portion of the unverified content; switching automatically the display, on the client device, from the output resulting from the opening of the unverified content at the temporary virtual machine to the opened unverified content at the client device; and terminating the connection with the temporary virtual machine.
