I love the bit about them saying when they visited the site it exhibited risky behavour
Since I've been a member I've been on here loads and not once have i encountered system instability or had my details hacked etc.etc.
Yet more corporate security company scare mongering (check their reasons and most of it is rubbish), even if a website run the latest available software there will still be so called vulnerabilities due to bugs etc. that have not yet been discovered.
For me the main reason for selling my PC's and moving to Mac's as i then don't have to worry about all that security apps that you had to buy owning a PC and the problems & worries they then cause.
