When using a packet sniffer, I notice a lot of packets being sent to a bunch of ISPs (such as axion.ca, wanadoo.fr/orange?, bresnan.net, zebra.lt) usually all at the same time. Here's a screenshot of the hosts in SmartSniff. I happen to live in none of these hosts' countries, so this is very strange.
Is this a normal thing, or maybe a side-effect of an infection?
