I saw the 'TradeAnalytics' project website and had to lie down for a few minutes until I felt better!

Vanilla Microsoft Security Essentials and firewall seem to keep a VM pretty safe over here and it blocked some obscure trojans/keygens I fed it for testing, that other Antivirus software didn't. As long as you're not running servers on the MSWindows box and it's constrained to access from your LAN, it *should* be OK. Whether you have a dedicated VM for MSWindows or dual boot into it, you can use xfreerdp on your Linux with RemoteApp on Windows 7 to access a particular MSWindows application remotely from your Linux desktop. I think that it needs Windows 7 Ultimate or one below that to work. Tried it with Windows 7 Professional and applications would not launch (some SSL IO error if I recall). PS. Mark, please let us know if you start providing virtual tutorials on installing and running these TradeAnalytics packages - I would be very interested to find out how to use them. :-) -- Regards, Mick
