Help removing our website from blacklist

We have checked our website with the scanners and nothing is showing up, but avast is blocking the website. Can you please help. The domain is layerdental.com.

Thanks,

590 domains on same IP http://www.urlvoid.com/ip/166.78.201.132/

We do have many websites on that server. But none of them should be blacklisted.

Please let us know if there is one.

Avast team is notified, check back tomorrow for possible reply
