Our Newspapers site was appently hacked?

The night before Thanksgiving, I was trying to do my job of promoting the paper when I received a warning from Twitter saying the link was to an “unsafe site’, when I Google us it warned that “Warning – visiting this web site may harm your computer! under a malware warning; subsequent to the site url cause a scary red page to appear with a warning. Is this the sign of a hacker? How do we fix it. I am currently deleting all the thousands of c”comments” in the spam cue. Have tried to contact wordpress support personally, to no avail. H-E-L-P!
our “webmaster” has not been able to fix this in almost TWO WEEKS now.
Thank you
