Stealth Viruses

Viruses that attempt to hide from detection programs by hiding their presence in boot records or files. When such viruses are run, they install a resident extension. This resident extension intercepts various disk accesses, determines if its own code is part of the disk access, and removes the code before giving the data to the calling program. The result is that the virus can be in several places on the disk. Normal reads of the disk will not reveal it.
