What is "system scan recommended" on my mac mean?

Thanks for bringing this up. I did NOT ask for this software, and I took the advice of deleted it from my system. Here's a warning ... When I deleted it, of course, it went to Trash. Then I tried to empty the Trash. The system asked me for my User ID and Password. I did not provide that. I closed out that window, and was happy to see that the MacKeeper was uninstalled and gone from the Trash. Thanks again!

It will ask yo the reason why you don't want it any more. Just click on anything. It'll go to the Trash, and then you have to delete it from the Trash. Don't provide your User ID and/or Password when the system asks. Does close that request box out, and it will be gone. I hate this crap.

I have the same thing on Chrome browser. No extensions other than ones I had before that have caused no problems. Here's a screenshot of the popup.

You must have MacKeeper installed. Get rid of it. If this is a browser pop-up, then it's a phishing scam and should be ignored.

Helpful Links Regarding Malware Problems

If you are having an immediate problem with ads popping up see The Safe Mac » Adware Removal Guide and AdwareMedic. If you require anti-virus protection Thomas Reed recommends using ClamXAV. (Thank you to Thomas Reed for this recommendation.)

Open Safari, select Preferences from the Safari menu. Click on Extensions icon in the toolbar. Disable all Extensions. If this stops your problem, then re-enable them one by one until the problem returns. Now remove that extension as it is causing the problem.

Fix Some Browser Pop-ups That Take Over Safari.

Common pop-ups include a message saying the government has seized your computer and you must pay to have it released (often called "Moneypak"), or a phony message saying that your computer has been infected, and you need to call a tech support number (sometimes claiming to be Apple) to get it resolved. First, understand that these pop-ups are not caused by a virus and your computer has not been affected. This "hijack" is limited to your web browser. Also understand that these messages are scams, so do not pay any money, call the listed number, or provide any personal information. This article will outline the solution to dismiss the pop-up.

Quit Safari

Usually, these pop-ups will not go away by either clicking "OK" or "Cancel." Furthermore, several menus in the menu bar may become disabled and show in gray, including the option to quit Safari. You will likely have to force quit Safari. To do this, press Command + option + esc, select Safari, and press Force Quit.

Relaunch Safari

If you relaunch Safari, the page will reopen. To prevent this from happening, hold down the 'Shift' key while opening Safari. This will prevent windows from the last time Safari was running from reopening.

This will not work in all cases. The shift key must be held at the right time, and in some cases, even if done correctly, the window reappears. In these circumstances, after force quitting Safari, turn off Wi-Fi or disconnect Ethernet, depending on how you connect to the Internet. Then relaunch Safari normally. It will try to reload the malicious webpage, but without a connection, it won't be able to. Navigate away from that page by entering a different URL, i.e. www.apple.com, and trying to load it. Now you can reconnect to the Internet, and the page you entered will appear rather than the malicious one.

I have the same image appearing, which I cancel, but it returns.

I opened up Extensions: No Settings - so nothing to identify Mackeeper.

Hi Kappy

I've followed these instructions but when I try to drag mackeeper app to the trash it won't go in the trash and nothing happens. Do you know what might be happening? I have made sure to quit the app etc.

Thanks
