Hi! I suddenly want to try test my security setup against a real malware. To avoid the worst case scenario of virus penetrating through my setup, I realized that it is good to do the test in a virtual environment. Can you recommend me a FREE virtual software that doesn't need to reboot everytime you turn on or turn off the software? I saw some screenies where there are two windows runnning at a sametime, the virtual environment was in a small box. Is it Virtual Box? VMware? Is it free? Thanks!
