Both my GF and I browse on separate computers, both of which have Norton Anti Virus installed. About a month go I got an automated message from NAV that the Sri site had tried to install a rootkit on my hard drive, a particularly severe type of virus. Today my GF got the same message.
My assumption is that the problem is with the server that hosts their website. It's likely that it's operated by a 3rd party company.
I suggest you go to Menupages if you need to check their menu.
