Virus Scan Windows 8 Bootcamp Partition from OS X? Is there any software I can use to scan a bootcamp partition on OSX for viruses from OS X?

I prefer to run the scan from OS X because:


Typically Windows anti-virus solutions are more like full suites that
require an installation. I do not wish to install anything like that
because it would incur a performance penalty. 
As I understand it, running the scan from outside the OS you're
scanning means that anything potentially malicious on the OS won't
interfere with the scan.


I suppose I could use a bootdisk of some kind but that is difficult because some bootdisks are not compatible with macbooks. 

So I figure if OSX is already hosting/aware of the Windows partition I should be able to easily scan it from OSX right?
Two problems:


I am not sure of any good Mac solution that will have the coverage of Windows viruses that Windows tools such as Security Essentials do. ClamAV may have pretty good signatures, but I can't vouch for whether it does or does not have a comparable scan and fix ability to a commercial product. Mac virus scan programs may be better, but again, they would probably have more focus on Mac viruses.
By default, NTFS partitions are not writable on Mac OS X. You therefore could detect, but not fix or remove, viruses from your Windows partition. The only way around this is to purchase a commercial product such as Paragon NTFS, or go through some interesting challenges to get open-source drivers to mount the partition read-write.


If you use Microsoft's offline version of Security essentials (http://windows.microsoft.com/en-us/windows/what-is-windows-defender-offline) and your Mac is reasonably new, you should be able to make a bootable USB drive that will work - just insert it and hold down Option as you power on your Mac.
