Parallels Desktop for Mac is the first solution for Intel-Macs that gives you the flexibility of running Windows on a Mac simultaneously without rebooting.
NOTE: Parallels Desktop 3.0 for Mac updates your virtual hard disk format to provide the ability to recover from failures using snapshots. If you want to revert back to an earlier version, you will have to uninstall Parallels Desktop 3.0 for Mac and reinstall the earlier version.
It is fast and flexible by enabling you to run critical Windows-only applications like Internet Explorer, Outlook, Project, Access and Quicken at full speed. Because Windows is completely isolated from your OS X, there is no chance of infecting your Mac with Windows viruses.
