Le site sluniverse.com est-il sûr ?

The website is infected with something, I doubt it is the fault of the owner, but be wary, as you will get random popups that take you to other webpages. The computer I've used to access the site is clean, and the popups seem to only come around every so often and usually as in-browser javascript messages that reload to a different, ransomeware or malware-related website if you don't click off. I'd be wary anyway.
