[CarolG1]

I need to run Windows XP under Parallels. How can I protect both the XP system and my Mac OS from intrusions coming while Windows XP is active?

Hey, please explain in details what would you like to do?
For example you can isolate your VM from MAC or install an antivirus.

I only need to run Windows XP and an old DOS application under Parallels. I am open to any technique that could accommodate this. How can I isolate XP from my MAC? and what antivirus program is currently available that will work with XP? Or is an antivirus program on the Mac sufficient? Thanks.
