Jeffrey has been on a dating website and now he's having trouble connecting to the internet. He has been getting notified that his cookies were disabled. Leo says it's DNS malware that has redirected traffic through the DNS servers to control what he sees. It could have impacted his computer, or his network's router. Since Jeffrey has only seen it on his computer, that's an easier thing to repair. He should backup his data, and then format his hard drive and reinstall his OS from a known, good source.
