Recently federal authorities arrested six Estonians, who were running a virus called DNS Changer. Almost a half million computers are still infected worldwide, so it’s recommended to check your computer if it has been affected by it. Infected computers are redirected to Rove Digital domain name servers in U.S. and Europe, which were used to change user searches, redirect to malicious websites, replace advertisements, block your anti-virus/anti-spyware software and recommend fake security products.
Although FBI has took over the control of these DNS server and they are producing to the legitimate DNS answers, it’s still highly recommended not to use them. The main reason is that FBI will most likely discontinue this service on the 8th of March 2012. Keeping your computer infected will still block many anti-virus software or websites, and it will hide your security updates. You see, that it’s very important to clean your PC from DNS Changer virus. It’s common that this poisonous virus comes along with other malicious Trojans, like Trojan.Fakealert, Trojan.DNSChanger, and Trojan.Generic.

The U.K. energy consumption guide

I’m a sucker for anything cute and bubbly, and the U.K. Energy Consumption Guide created by Epiphany is no exception. It combines a vertical scrolling site with a lot of data visualization about different types of fuel and how they’ve been used historically. Most of the charts are solid and the interaction adds an even higher level of clarity and understanding.
While I like this circle packing chart, I’m sure there will be doubters. It’s very similar to McCandless’ natural gas visualization that received a lot of flack. But generally speaking, anything that is engaging and welcoming garners a little extra time from the visitor to make sense of it.
