Was just going to say "Hi" and tell a funny. I was using an old DOS version (4.0) of DesignCad 3D (easy way to create models for Raylib OpenGL game engine) and had it along with one of the last DOS versions of 2D on my jump drive.
When I plugged it in at work, the antivirus noticed "encrypt.exe" for scrambling the BASICAD source files from .BSC to .BSX.
McAfee cried "Foul!" and conveniently erased encrypt.exe from both my old 2D and 3D versions off the jump drive.
Didn't touch anything else, just removed those two.
Not that I've ever needed to encrypt any of my BasiCAD files, but I thought it was funny.
