Why is my Win7 PC tryine to encrypt my hardrive after installing the SPARK USB drive executable

  • So after downloading, unzipping, and running the executable to install the SPARK PC USB driver on my Win7/64 machine, I keep getting a popup window to encrypt my hard drive, and back up my certificates and encryption keys. I tried the install several times, and went into task manager and killed the encryption app there each time. Is this some legitimate action of the spark driver install? If so.....WHY??? I am concerned that the file may have been hacked with a ransomware - encrypt - pay for the key - scheme.
