Gameover Zeus, which experts say is 'sophisticated' and capable of evading anti-virus software, infects a user's machine when they open a PDF or click on a link sent to them in an email.Once it is set up on the computer, Gameover Zeus will intercept all financial transactions and rewrite them, so that payments made by the user will be redirected into other accounts.The malware also has the power to disguise unapproved payments that are made, meaning that thefts might have occurred even if accounts appear normal.'It keeps track of balances; it automatically corrects the numbers on the balance. It's so sophisticated that it hides its tacks,' said Nick Savvides, senior principal systems engineer at software giant Symantec.The malware has hit computer users around the world, with the most incidents reported in the U.S. and Italy – 13 percent and 12 percent respectively. Seven percent of incidents have occurred in the UK.
