The features and benefits of using equalizers with my computer

Hi!
I am juts new hear. Can you tell me something about equalizers in computer? I would like to ask about FabFilter Pro-Q 2. What are the best features for using it? What are the system requirements for this software? Can you give me what are the special features of this software? Can you give more information on what are the pros and cons of this? Which platform will it work? Can you tell me what are the supports that I can get if there’s any problem with it?
Thank you!
