Are you positive it's just not an issue with your computer and not the site? If it is your forum then change all passwords stated above. Including your hosting password. Also look to see if there are any updates for your forum software.
looks like someone or some team inject your site , just contact your hosting provider, it's your hosting problem.. if it problem up again, request a dedicated IP, it's about $1/mo <- more secure i think and remember this is a machine
I agree with contacting your hosting provider, any decent host will be more than happy to help you. Dee
