Hi VFN,
Apparently the IP is being blocked by avast! because of spam abuse.
Although this report is not very outspoken: https://www.projecthoneypot.org/ip_31.7.63.194
IP might have been involved in forum spam and therefore being blocked 
The domain has migrated from 2013-10-14 myrtv.eu 81.17.20.3 to the IP it has now.
