DeepFreeze is wonderful if you are not an adventurous user,, I have a number of machines that have that system installed and granted that it does as it says, however, if you do not get the scheduling for the thawed periods correct with your scheduling of AV software updates, and security patches, and internal updates,, it becomes a bit of a nightmare,,
if you want to try something like that product,, try the newer version called DeepFreeze - enterprise,, released in sept 2003,,,
it allows you to thaw the machines on the fly,, and allows for up to 100 gb as a personal "thawed" area,,
it is a good tool, however, you NEED to put the time into configuring it!
On the virus issue btw, I would agree that there are versions of KLEZ that are a pain in the arse! your explanation does make goood sense,,
