I have a friend who is keen to give H&H a shot, so I sent him the link and told him how to get started etc.
Being the paranoid type however, he scanned havenandhearth.com for viruses before getting on to register. When I saw him last night, he told me he'd picked up 13 different viruses, same results on three different anti-virus programs.
I'm emailing him now to ask for a screencap of his results, thought I'd post this now so someone else could verify/the admins could check for themselves asap.
