Sounds good to me but...
I still need a good rescue CD with an AV on it for such purposes. I like to make at least a 95% assurance nothing may be left on the hard drive. If they have something truly valuable to protect, I may wipe and re-install, then update all scanners before checking the backup files. If they have a business, and can wait at least two days for all definitions to update, I try to scan later, and just not recover all backup files right away.(especially by incremental backup date)
