Nearly 3 lakh DNSChanger virus-hit computers, including over 20,000 in India, may lose Internet access from Monday, July 9.
DNSChanger is a malware computer program that redirect the Internet traffic to fake websites.
Servers setup to provide temporary relief to DNSChanger victims will be shutdown on July 9. As a result, all computers infected with this threat are likely to no longer be able to access the Internet.
"If users' computers have the wrong DNS settings for the servers, they will not be able to access websites, send e-mail or use Internet services," security firm McAfee statement said Thursday.
The ring behind the DNS Changer virus, discovered in 2007, was shut down last year by the US Federal Bureau of Investigation (FBI), Estonian police and other law enforcement agencies.
Because the virus controlled so much Web traffic, authorities obtained a court order to allow the FBI to operate replacement servers which allow traffic to flow normally, even from infected computers.
But that order expires Monday, when experts say infected computers will face an "Internet doomsday."
Security firms and experts are advising all users to check if their computer is infected immediately, or risk losing Internet access.
