Comments on ntvdm.exe

may make your computer explode
On my pc, ntvdm.exe took 99% of cpu power when I started cmd or regedit. After researching, I noticed that cmd.exe was not being loaded, but cmd.com was (the same with regedit.com). This is obviously very suspicious and made me check for these files; I found both in the system32 directory with a size of 2 bytes. Removing these solved the problem. Some spyware must have instlled them to block access to these Windows tools.
