Firstly, nice article, and thanks for sharing your obvious hard work with the rest of us.
I took the time to read the text on the screendumps you showed, and right from the start the hairs were standing up on the back of my neck : malware. The text read like the poor english manuals for the electrical goods you bought from tandy 15-20 years ago. The graphics were quite convincing. If they get the english right ...
I've been caught myself way back when I was using w98 and did not understand computer security. So I trashed the machine and lost some of my data (not recently backed up) to clean it up, and be sure. I think it fair to say 'gee thanks bill' for the crap that entailed, but the fact remains that it *could* happen on any system.
Now I use my Penguin friend for all online stuff, as I don't trust bills crap. This is not smugness, just bitter experience.
Regardless of the operating system you use, and the security software you use, there *ARE* weaknesses in your system, and they *WILL* be found. Security software may not be current to the threat and will not necessarily protect. Using the admin account on your machine when online is idiotic as any crapware gets admin privileges, so don't do it.
Therefore *PLEASE* think about what you are doing, where you surf, and don't bloody use an admin account while doing it !
No legitimate coder leaves bugs in code at time of release. How many have looked back at their code of say 6 months ago and thought on occasion WTF was I doing when I wrote that ? Bugs slip through sometimes by hiding in plain sight. The only way to address this is to install the updates and thank all involved in finding the issue and resolving it.
Paris cos you're bound to get 'infected' while surfing for/on paris ...
