The "internet blackout" will take place July 9, a newspaper reported Wednesday.
The computer virus called "DNSChanger" sends internet users to unintended and illegal sites. A report said the virus originally emerged in Estonia.
The virus also blocks infected users from visiting secure sites that could help them rid of the worm.
The FBI detected the infection some time back and had set up temporary servers to keep the infected computers working. But reports said it was costing much.
The temporary servers were created to allow companies to remove the worm from their infected servers. Those affected had 120 days to get rid of the malware.
After FBI warnings, the number of computers infected with the virus plunged, and now most are in the hands of private individuals, not companies.
