It sounds like you have something on your Mac which is trying to access this questionable website. Based on my quick web search, the website appears to serve adware, which isn't useful to you.

First, if you haven't restarted your Mac recently, please do so now. MacOS removes malware at login, so there's a chance this will go away on its own.

If you are still encountering this error, click the Safari menu and choose Preferences. On the General pane, look for what your homepage is set to. If it's not something you recognise (or http://www.apple.com/startpage/), I would recommend changing it to something like https://duckduckgo.com/, which is a search engine. Sometimes these adware things change your homepage basically just to annoy you, and this message might appear because Safari loads your homepage when you launch the app, depending on your settings.

If the above hasn't worked for you, report back and I'll see what else I can suggest.

1. Use MalwareBytes for Mac to remove malware/adware.

Install guide: https://support.malwarebytes.com/docs/DOC-1817

Uninstall Guide: https://support.malwarebytes.com/docs/DOC-1190

The installer may ask you to allow it in Security & Privacy /System Preference. Allow it.

2. Disable all extensions and test.

Turnoff or uninstall extensions.

Section: Manage extensions: https://support.apple.com/guide/safari/use-safari-extensions-sfri32508/mac

3. Choose a search engine.

Delete all text in the Smart Search field, click the magnifying glass , then choose a search engine from the list.


4. Set your Home Page. https://support.apple.com/guide/safari/set-your-homepage-ibrw1020/mac

5. Restart your Mac.

6. Launch Safari holding the Shift key down.

If you are using Mac OS X 10.9, that is actually not a malware or adware issue. This problem is, unfortunately, normal with Mac OS X 10.9.

Recently, 10.9 systems began to have problems verifying certificates for certain sites. The bluekai.com sites, as well as the Oracle site (who owns bluekai.com), are among the affected sites. I've also seen recent reports of the problem with adnxs.com.

I am not clear at this point what the cause of the problem is, but I have been able to confirm this behavior on a freshly-installed, clean 10.9 system.

Unfortunately, there are only two options available to you. One is to upgrade or downgrade your system. Mac OS X 10.10 and higher do not suffer from this problem, and strangely, for whatever reason, Mac OS X 10.8 is also not affected.

The other option is to stop using Safari and switch to Chrome or Firefox.

I was experiencing this only on my Mac Pro, on MSN and Ebay.

I was in the process of installing the recommended Malwarebytes software, but had an older OS and was forced to upgrade.

Upgraded to High Sierra 10.13.3.

Pop up appears to be gone, so far so good.

My iMac is now 8 years old and I think this is the problem, I cannot upgrade anymore (so Apple tell me), but I have now downloaded Google Chrome and am using that, so far no problem. So I shall carry on using that as I don't think my iMac will be comparable with High Sierra.

Thank you for replying, I am very grateful for all the help on here

You should be able to upgrade at least to El Capitan if your computer is 8 years old. If you are using Mavericks, you can upgrade to El Capitan. Try the links below.

How to get macOS High Sierra

Sierra download

You can try to download it at the link below. If it won't let you, then your only options are to upgrade to Sierra/High Sierra or find an older computer where you can download it using your Apple ID.

El Capitan

Hi Thomas

I started getting this pop up today, having previously had the stags.bluekai pop up. The worrying thing is firstly it started after I was browsing safari and a malicious virus page popped up and everytime I tried to close it with the x, it brought up the print window. I managed to force quit and reset safari and removed all website cookies, but since then my machine is running quite hot and now I get this in.adnxs.com pop up, which started when I went on amazon (didn’t happen on amazon earlier today).

I’m concerned as most people on the forums are saying this is adware/malware and my information could be hacked. I’m unable to run Malwarebytes as my mac is running Mavericks. I’m not running any extensions in safari and I’ve done a manual check in the launchagents/daemon folders and not found anything unusual.

The popup doesn’t happen in Firefox, but I prefer safari.

I can‘t update the Mac as certai software will no longer work and I can’t find a trusted adware removal tool to work on Mavericks (I was advised on another forum not to install any adware removal app other that Malwarebytes).

Any help/advice would be gratefully received as I’m starting to really worry that I’ve messed up my Mac.

I prefer Safari as well, and I wish I could be more helpful and get yours working properly again. Aside from Apple's suggestion to update your OS, which you say you can't do, look at what else they say here (including checking your Applications folder):

How to block pop-ups in Safari - Apple Support

Don't forget to check what homepage Safari is set to, since malware often changes the homepage to something else.

Also, maybe double-check that you're actually on Amazon's website, and not a website that has been carefully crafted to look like Amazon and serve adware instead.
