EcommerceTimes.com reports that a serious new piece of spyware comes to computers simply by surfing the web. The JpegOfDeath trojan was first reported on Usenet and it can allow your computer to be taken over by hackers. Experts are worried a mass mailing worm will be created in the future using the new type of JPEG trojan. Graham Cluley, a consultant for Sophos, told the EcommerceTimes.com that "security firms are especially concerned about the vulnerability and the ensuing exploits because JPEGs are such a commonly used format for viewing images online."
