Who say that we know what we are doing?
Never download something from a doubful pirate site.
What are you willing to pay for this?
But, in all serious. I haven't had a problem with HH yet, but I mostly us Nopy for download here, if available and some others. As far as I know, I my AV haven't entcountered a virus yet from a game here (doesn't mean anything at all, as my AV could also be bad at its job...).
If you are unsure, use some site like
You must be registered to see the links
and let them scan the files. If more than one AV used there having an issue then it
could be a problem otherwise it is more
likely that one single AV have a problem itself.
But foremost for security it is not possible to be 100% certained. Thus often your own head is among the best protection if you are using it right.
