who is responsible

[shukla_swapnil]

Well recently i had my friend's website hosted on a free host, subject to a malware attack and since then everyone to visit - if he has protection, he gets an error message and if he does not then the computer is at a risk of getting infected. I m not posting the link for obvious security reasons. So now i would like to know whose resposibility is it to maintain a clean space - the host or the owner of website and also who might be at fault. I am not quite aware of the sttus of same.
