IDEA Cellular's website seems to be sharing more than just Telecom Plans and VAS details: clicking on www.idecellular.com will not harm your PC, but selecting the option "Idea Now In Orissa" may do more than just give you tariff details...
"Idea Now In Orissa" links to http://www.bythepeople.in/orissa/ which when opened generates a warning from Anti Virus software that the website is infected with a Trojan. Kaspersky Anti-Virus 2009 informs the infection as "TROJAN-CLICKER.HTML.IFRAME.AQB"Emails to Idea have evoked a response that the same is being looked into. Till such time as it is looke into, ensure that your browsers stay clear of the website and its potential malicious code.
