Facebook has started a campaign of notifying victims of the DNSChanger malware. The social network notifies all users who visit its site that their computers will be cut off the Internet on July 9, if they don’t clean them until that date.
A message from Facebook contains a link to the DNSChanger Working Group's website, which provides all the necessary data about malware and instructions on how to remove it.
“As a result of our work with the group, Facebook is now able to notify users likely infected with DNSChanger malware and direct them to instructions on how to clean their computer or networks” – the Facebook said in official statement.
DNSChanger is a malware that hijack Web search queries, provide users malicious advertisements and redirect users to fake websites. Crooks make infected computers use DNS servers controlled by them.
FBI was investigating case of DNSChanger malware spread for two years. It was shut down in November 2011. Fake DNS servers were replaced by legitimate ones that would be taken offline on July 9. After that computers still infected with DNSChanger will no longer be able to access the Internet.
According to the DNSChanger Working Group, there are still more than 350,000 devices infected with DNSChanger, out of the 4 million that were originally infected.
