Hi and thanks in advance for the fast response.
The website www.stefanodobleja.ro has been infected a few months back with a malware and it was impossible for the administrator at that time to clean it (it was fully compromised). As the back-ups were also compromised, the owner of the domain closed that deal and made an entirely new website using Joomla 3.x.
The new site presents no infection, as you can see here https://sitecheck.sucuri.net/results/cnpstefanodobleja.ro
So, I kinly ask you to remove the blacklist of that website.
