Some Mac users report an annoying issue that considerably deteriorates their browsing experience—stags.bluekai.com popup. The occurrence of the message is associated with browsing eBay; however, it can also appear on other websites. Given that the randomly popping up message concerning the invalidity of a website certificate prevents Mac owners from navigating the Web without interruptions, it is necessary to find a reliable solution for the problem. This article aims to help Internet surfers to reclaim their digital space by removing the phony certificate invalidity notification.
Why the Popup Appears?
Prior to enumerating possible removal options, it is necessary to understand why the message appears. BlueKai is a company that specializes in the aggregation of consumer browsing data, which is distributed to advertisers for profit. Due to a recent change of the commercial relations between eBay and BlueKai, the tracking scripts of the latter have lost verification, which is why Internet surfers see the message during online shopping.
How to Remove the Popup?
Regardless of the legality of the certificate invalidity notification, it is still extremely annoying. In addition to being unsolicited, the message might be a sign of malware infection that aims to trick a user into installing questionable software, which can compromise the security of their system. For this reason, it is necessary to ensure that the pesky popup disappears for good.
Start by closing the tab that contains the notification by pressing the Command+W key combination. If the tab cannot be closed, it is necessary to quit Safari. In case it is not possible to close the browser, try force quitting it with the help of the Command+Option+Esc combination. In a window that opens, select Safari and click on the Force Quit button. The next step is to relaunch Safari. Note that the tab with the rogue notification will reappear upon the launch. To prevent this from happening, hold the Shift key when starting the browser. Even if done correctly, this action might not always help. Additionally, all tabs that were open will also be gone, which might cause a loss of necessary data. Therefore, try disconnecting from the Internet and launching Safari normally. When the browser opens, close the malicious webpage containing the message. Then, open the Preferences settings of Safari and click on the Privacy tab. In the tab, select the Manage Website Data option and select all cookies associated with BlueKai. Then, use the Remove button to delete stored data. Relaunch the browser.
An alternative approach to solving the issue is to change Safari security settings. In the Security tab of the browser, choose the Block Pop-ups and Fraudulent Website Warning option. It is also worth checking whether the malware has installed an extension causing the message to reappear. It can be done in the Extensions section of the Preferences settings.
Another way of addressing the problem it to update a Mac to the latest version of macOS High Sierra. The macOS has a built-in tool for removing known malware and viruses every time Mac is restarted.
If the steps outlined above have not been conducive to the eradication of the popup, it might be beneficial to install a third-party cleaning utility on a Mac. Such adds are specifically designed to scan and remove adware and malware from a computer without requiring tech expertise on the part of a user.
