Something is injecting malware into my HTTP traffic

[Etzion Bar-Noy]

Traceroute is useless. Only traffic directed at port 80 is routed through
the proxies. Nothing else, meaning that ICMP, used for traceroute, would
got to the target directly.

There are methods of identifying transparent proxies (you could probably
ask Google about them), however, this is not one of them.
