Incorrectly blocked 67.195.145.142

[rodeurramjet]

I tried to visit www.hyperdynesoftware.com and Malwarebytes 'website blocking' function blocked access, with the following message:

Blocked access to a potentially malicious website

67.195.145.142

Type: outgoing

Port: 5870

Process: avastsvc.exe

I thought avast might be interfering somehow so I disabled it but the error message still appeared with

Port: 5878

Process: firefox.exe

However I looked up the IP address of the domain and it was 122.108.176.73, why was it blocked then?

Thanks
