Carole Thierault, senior security consultant at Sophos, said attacks like this were a "nightmare" to defend against if people did not regularly update or use anti-virus.
"It is important to ensure that your security software is capable of identifying and blocking malicious websites," he said, "as you can be sure that the criminals behind this will be constantly updating their malicious files to try and avoid traditional security."
So, like most of these knee jerk scare stories, you have to go out of your way to look for it, or be incredibly computer un-savvy to actually get compromised by it.
