^Well, my antivirus would catch an issue like that, wouldn't it?
Not necessarily, an antivirus is never 100% effective and up to date. So there is still a chance, but probably unlikely if it's only happening here and to other members.
I did a bit if looking around for similar problems using the website name you gave and found this: https://productforums.google.com/forum/m/#!topic/adsense/szfNNkPrkLI
no definite solutions though? I don't know if Vixx uses AdSense though, I haven't seen an advert here is years.
I also found some topics relating to a malware that redirects the garden site, but it was more to do with redirects after opening multiple tabs.
