This doesn't seem to be clearly documented anywhere, but the new version of Daemon Tools 4.0.6 seems to have fixed a collision that it had back with version 4.0.3. The bug was exhibited by a blue screen PAGE_FAULT_IN_NONPAGED_AREA in mfehidk.sys. The blue screen was so terminal that one of the apps had to go on my family members' PCs in order for them to work. Because the kids are not allowed to have the physical media (in order to protect it), we put all of their software on the network and their PCs in the form of ISOs. Hence I'm very happy that McAfee ASAP and Daemon Tools play well together again!
