Recently there was long thread about the BCA. I can now post possible answers to some of the questions, such as "Why is the BCA still raising membership prices when there is a significant amount still left in its coffers?"
Yep, I've already contacted them to request we're removed from their blacklist, but I suspect it relies on Toby contacting Google first and he's away from his computer at the moment.
I recommend using Sandboxie for this sort of thing if it happens again...you can then proceed to ignore all the virus/malware warnings safe in the knowledge that your computer can't be compromised.
