It's much faster than to do analysis on traffic capture (which may not even reveal certain types of infection). If you think your computer might be infected: back up all your important files to an external drive, and then re-format your drives and re-install your operating system from scratch. I have studied networking at university, and I have a few years experience doing this, and I still look at network traffic sometimes and get stumped trying to work out exactly what's going on, let alone whether it's malicious or not. This is genuinely a full time job that people do, that requires multiple years of experience, and usually some academic background or training in how networks work and how to understand network traffic.
