> Security products flag cookies as malware

If you're saying cookies shouldn't be flagged by antivirus, that's wrong. Cookies can be associated with malware in any number of ways[1], although grayware (especially adware), which antivirus also flags depending on configuration, is a more likely culprit.

1. Check out PyExfil, for example: https://github.com/ytisf/PyExfil. Cookies for data exfiltration. DNS controls on firewalls are there for similar reasons.

Oh, exfiltration? Yeah, you're like every other malware 'protection' snake oil salesman.
