DNS Changer Malware- its effects and how to secure your computer from this

DNSChanger Malware has been infecting computers from November last year.

The roughly half a million devices are still infected with DNSChanger.

Infected machines had their Domain Name System settings altered so websites would redirect to servers controlled by the criminals. The scammers reportedly earned millions in affiliate and referral fees by diverting users through those sites.

Computers affected with this Trojan will not be able to access Internet after 9th July.

If infected machines are not fixed by then, their Internet connections will go dark.

On Google, infected computers will see a warning atop their screen when completing a search (see below).
