An expensive and unnecessary move imo. I got a linux virtual root trojan via a Windows '98 HD while booted in Windows. Some viruses are made to load vai Windows and attack linux and vice-versa since they can pass unrecognized thru each OS's virus scanner.
My solution was to dump '98; write 0s to the linux HD; reload Mandrake 8.1 and put XPpro (fat32) on the zeroed-out Windows drive and reload my database. Worked like a charm. The name of the virus was CodeRed.C. It's an NT4-based virus. It has 3 NT4 payloads and uses the 2000 Server exploit simply for transmission.
The NT5 OSs are nice though. However, you can pay $400 for XPpro's protected memory and file system or get the same for free using Mandrake 8.1 with JFS:Reiser partitioning.
Have you tried out ext3? I am having fun with my backup database server pushing a high load on it and pulling the power plug on it to see it recover without skipping a beat. I have to try out JFS:Reiser.
