This is all about malware that some users will have on their PC, that will take them offline on July 9th, when the FBI shut down their DNS assistance for infected machines.
Currently, those who are infected don't know it, as their botnet-controlled machines are federally-assisted to find the correct DNS (routes around the web). The FBI rolled up the botnet and installed their own public DNS servers to help the large numbers of infected machines that were being re-routed to the malware authors' sites.
When the feds finally shut those DNS servers on July 9th, some people's PCs will just take them into a blackhole, as their internet won't work. They'll know about it at that stage, and will finally have to disinfect their computers. An estimated 350,000 people will be affected.
It has been estimated that 20% of all PCs globally (that's 1 in 5) are botnet slaves. This means that, unknown to the owner, their PC goes to unauthorised websites without them knowing. This is done for all sorts of reasons, such as PPC click fraud, DDOS attack armies, and collection of personal data for CC fraud. The owner is completely unaware their PC is being used by a 3rd party.
It's hard to offer people advice about it, as they just don't take it, or think they know better. If their PC stops connecting to the web on July 9th then they'll have to fix it. That won't be possible for the majority of those affected, so they will need to take the computer to a professional. At that stage they will get the proper advice and with luck will take it.
