I set up a Linksys router for him to use with his broadband service. For some reason, he reset the config on the Linksys, and connected it up without wireless security, and also with the default admin password for some time. As you would expect, both of the Windows computers got 'slow,' and the desktop stopped connecting to the internet completely for some reason. As I logged in remotely to 'fix' things, I noticed on the Linksys' log that the laptop was making seemingly random connections to high-numbered ports on various IPs. I did an nslookup on the IPs to see that they were all either in Canada or US, with Comcast and other ISP addresses. Is that a sign that the computers were in a botnet? Are the other hosts part of the botnet too? (I have since rebuilt the Windows hosts, and these connections are not happening now. I have also secured the Linksys.)"
