Windows 7 VM Get Virus From Other Windows Machine Infected on Same Home Network?

I realize my Mac Pro cannot be infected by viruses passed along from my Windows 7 VM running under Parallels 6, but...

Do I need to be concerned about my Windows 7 VM becoming infected by another infected Windows machine on same home network?

Thanks

 

Actually, your Mac Pro Parallels host could get infected via a VM. All it would take is for the VM to pass along a Mac virus through folder sharing (if enabled) or through a vulnerability in the VM->host isolation. I haven't heard of any malware that does that, but it's only because nobody is trying hard enough (we hope!).

The Windows VM's are as vulnerable as physical machines. Unless a VM is completely isolated - not on a network with other machines/VM's, and not connected to the internet - it pays to run anti-virus software in it.
