The following are the most likely reasons why your computer got infected with QSD23:

Downloading and Installing Freeware or Shareware

Small-charge or free software applications may come bundled with spyware, adware, or programs like QSD23.

Spyware frequently piggybacks on free software into your computer to damage it and steal valuable private information.
