Just want to say that I think that website isn't problematic. Sorry for misunderstanding, it's cause believe that security suspicious content can be in that kind of website (porn). I'm user, but not IT expert I'm gonna do what Dmitry_Rus suggested and tell you results.
you can aslo submit a False Alarm for that website here : https://support.drweb.com/new/urlfilter/?lng=en
add that website to Spider Gate's exclusions, works for sure by the way
but please first send that URL to Dr.Web VirLab, analyst will chek it again, and if their response still was the same, you need to underestand that the website have an infection for sure, just you cannot see that. trust the analyst
You're right I will first send URL to VirLab and wait results. Thanks guys!
