Every time that upon the moment I log into Audio Karma my computer Anti Virus blocks a virus attack. This site is hacked.

The site may be clean, don't doubt it, but I don't know if they can see what may be in the ads especially if it's an intermittent thing. A drive-by, as someone else put it.
What I'm seeing is that it is coming from IP 78-159-122-88 which Whois shows coming from Hong Kong.
