How to Stop Malware hits?

For two days, a webpage has been trying to access my system and avast keeps blocking it. How can I prevent the page from accessing my computer so the block shield isn’t pinging all the time?

I’ve attached a picture. It will run up to 50+ hits in less than 15 secs.

Please follow this guide and open a new topic in viruses and worms section: http://forum.avast.com/index.php?topic=53253.0

Attach the requested logs there.
