Node.exe being deleted

Question

I've hit a very strange issue with my windows 7 computer when trying to use node.js

Every now and then, when I run a node based command ie npm, grunt, yo I get an Access is denied. message, node.exe proceeds to then delete itself, and is no longer a recognizable command.

'node' is not recognized as an internal or external command, operable program or batch file.

Has anyone hit this issue? The last time this happened was when I tried to install yo globally. It crashed, then node.exe disappeared from the installation directory. The error/log trace doesn't seem to show anything other than the installation failed.

You may need to switch off your antivirus-software while running node on your windows computer. Some antiviruses detect node as an unsafe program.
