Picuki has abruptly shutdown and it seems their domain has been hijacked and redirected to Tikvib.com, the site itself contains a lot of malicious advertising and just clicking somewhere sometimes opens fake "security alert" popups, on mobile if you allow notification access it sends bogus virus warnings.
Anything related to Picuki needs to be removed ASAP until a replacement service can be found.
