I have updated avast software and virus signatures and it is still blocking the website. Please help.

Thanks.

Not your website is blocked.
But the IP is blocked.

The problem is that you are using shared hosting.
On the same IP are malicious websites hosted and therefor the IP is blacklisted/blocked.

http://urlquery.net/report.php?id=9120833

If you believe your website (url) should not be blocked, you can make a request by using the form on the avast website.
http://www.avast.com/contact-form.php

EDIT:
From virustotal: The URL scanner will only enqueue for antivirus file scanning those files that are not text or similar formats (HTML, CSV, XML, etc.).

No need/use to make the IP look like xxx.xxx.xxx.xxx
A simple dns lookup will show it is 184.82.176.34

Domains on that IP have an IDS alert for Detected a Dynamic DNS URL.
Malcode on same IP: p(nil): unknown_html ARIN US nic at hostnoc dot net 184.82.176.34 to 184.82.176.34 xxuz dot com htxp://us.qaa.xxuz.xxuz.com/mxgdaxk

“network operations center” in scranton, PA has a LONG history of hosting malicious content… i block every IP address that is managed by “network operations center” in scranton, PA… it doesn’t matter if they host 2 or 3 webpages that aren’t malicious… they just use that as cover, to try to argue that they are not a purely criminal operation…

blacklisted here http://www.apews.org/?

Hi Eddy, redwolfe_98 and Pondus,

Thanks for the additional feedback, info must be sufficiently convincing, so an Autonomous System that should be shunned.
