Safari prevents trackers from following you?
This safari cross-site tracking app, it lists Duckduckgo in the description. I can't find any file called duck...... I have a 2019 MacBook Pro and someone downloaded halloween font into my machine and it brought a mess of trojans, the machine is so new I haven't backed it up. Can I just reload the machine? I have ads popping up on Safari, I have tried emptying cache and history then restarting machine but as soon as I start Safari I get a bunch of tracking websites under preferences, I delete them and they come back. I have had Macs for 15 years and never used anti virus software, which is a virus in itself.
MacBook Pro 16″, 10.15
