@Superstitionsee I've not heard of EtreCheck, but I have used and am happy with Malware Bytes: https://www.malwarebytes.com
It sounds like something on the website. Check out the AdGuard plugin for Safari.
@scottlink @Superstitionsee agreed. I'm very happy with that product altho I use PCs.
@scottlink thanks, I will check out the plug in. Not crazy about Safari, but have so many passwords stored there, and have been slow to change that.
