Quick question about removal methods

If you have an infected system, wouldn't it be advantagous to remove the hard drive and mount it into a working system as a secondary drive and clean it from there? (I have a USB/SATA toaster.)

Wouldn't this ensure that the scanner was running in a "trusted" environment? Couldn't the MBR be scanned more reliably?

Are there any tools for removing malware designed to work on infected drives that are mounted on clean systems?

 

Of the people who get heavily infected with malware, a good majority of them do not have the knowledge to be pulling a drive, and/or are using OEM machines, in which that can void the warranty with some companies.

I personally think a once compromised drive can never be trusted ever again, clear of malware or not. But thats not something that people will want to hear, so I will leave it at that.
