iad-login.dotomi.com error message

going into preferences in safari, privacy, manage website data and picking remove all seems to have resolved the issue.

tl;dr the message does not mean you have been infected with malware, and just deal with it.

This is an error with dotomi.com's certificate. Safari is doing its job and protecting you. What is it protecting you from? Probably ads that will try and serve malware. Either way it is not Apple's problem to fix, but solely dotomi.com's.

If you Show Certificate and then check the Always Trust... checkbox when continuing then the message will go away, but you should NOT do this. If you are that bothered, email the webmaster of the site showing these dodgy ads.

This is not a sign that you have been infected (you may be by another vector), but Safari is protecting you from a misconfigured cert.

OS X Yosemite: Set the date and time on your Mac
Second, reset the stored cookies and website data in Safari.
Safari 8 (Yosemite): Manage cookies and website data
Third, you should still be able to access the internet in safe mode. See if the issue persists in there.
Try safe mode if your Mac doesn't finish starting up

I am also having this problem. The person from Apple doesn't seem to understand the problem. It's not that our certificates are not being recognized, it's that we have some malware call domiti, and we want to know how to get rid of it. Is Apple aware of the problem?

This doesn't work. I've googled it and the dotomi malware is apparently hard to rid your computer of. I've used various malware/adware/virus removal programs, reset and cleared everything with safari, etc, etc. It doesn't go away and makes it so certain images on certain pages won't even load and slows browser performance.

The website dotomi.com is not malware, at least not really. It's a website that serves ads on a lot of websites, e.g., news websites. But the problem remains: It shows all these error messages. I don't really feel like accepting their wrong certificate so they can serve me more ads.

I, too, keep getting this pop-up error message;

Safari can't verify the identify of the website "login.dotomi.com"

it is happening so often and preventing pages from loading that it's making Safari & computer unusable.

I did this: "going into preferences in safari, privacy, manage website data and picking remove all seems to have resolved the issue."

It helped for about an hour and the error message came back again and again. Are there any other solutions? This is very bothersome and many websites.
