I get constant messages such as; Gmail alert; 'account has been hacked', 'Critical virus alert', 'Your iCloud is being hacked', 'System Mac OS is infected!''
I only get it on my iMac (macOS Monterey version 12.7), which is up to date. Safari 17.0. Ziggo safe online (=F-Secure) scan runs without errors.
It are 10 different messages which appear in random order.
