A growing number of new viruses, including W2K.Installer and Win32.CTX intentionally do not infect xFP-protected files.

Windows 3.x is started with DOS firmly in control. Viruses infecting DOS programs can infect files started in a DVM without many problems. File-overwriting viruses will be able to spread under Windows 3.x as they normally would in DOS.

DOS parasitic viruses will usually fail to properly infect Windows executables, instead causing immediate file corruption and subsequent error messages. These steps might not work with advanced malware infections.
