I'd like to ask if anyone knows, one of my blogs' domain got expired and I didn't wanna renew. When I type in a web browser it shows a Japanese page with that domain (I thought it got a virus or hacked). And because I'm using shared hosting and I have another addon domain together with that expired one. So, if it's a virus, should I worry about the addon domain? Or just ignore that expired one? Or what should I do in this case? Thanks in advance!
(I went to hosting to delete all data related to it and went to google console to delete everything else too.)
