Spyware Removal from Mac, Windows and iPhone

I'm seeking a professional with expertise in cybersecurity and Mac/iOS systems to assist me with spyware removal from my devices. My laptop, a Mac, and my phone, an iPhone, are both experiencing slow performance, which leads me to suspect the presence of spyware.

What I've Tried:
- Factory resetting both devices has not resolved the issue.

Ideal Skills and Experience:
- Extensive knowledge in dealing with spyware
- Proficient in MacOS and iOS systems
- Experience in improving device performance post-spyware removal
- Good understanding of cybersecurity measures
