In response to the threat of the Flashback trojan, Norton has launched a free scan-and-removal tool. The utility follows remedies from both Kaspersky Labs and Apple, both which released their removal tools earlier this week. Apple's solution, which was released via Software Update, consisted of a Java update that was said to find and remove the "most common variants" of the trojan. The free utility weighs in at 0.6MB and can be downloaded from Norton's website.
