Internet Doomsday': FBI Gives New Deadline to Disinfect Computer of Malicious Malware by July 9 or Else

Earlier this year, we reported that any computer infected with a nasty piece of malware could be shunned from using the Internet by the feds. The deadline for that was March 8 but an extension was ordered to provide users with more time to clean up computers. Now, the Federal Bureau of Investigation has said all must be virus free by July 9 or be subject to was PC World calls "Internet doomsday."

The malware is a piece called DNS Changer Trojan that was the work of six men from Estonia who were arrested and charged in 2011. The malware infected more than 4 million computers in 100 countries and is relatively easy to spread, hence why the government is ready to stop those with the virus from accessing the Internet.

Individuals and companies have been working to scrub the malware from their systems but as of March at least one computer in half of all Fortune 500 companies was infected and more than two dozen government agencies had a carrier as well. PC world reports that estimates are more than 350,000 computers are still infected.

Before the July 9 deadline, consider checking to see if you have the malware here. If you don't check and clean your computer before this deadline and end up without Internet access, PC World explains you'll have to load the anti-virus software the old-fashioned way onto your drive through USB card or disc.
