Malware/Adware infections seem to be on the rise. Watch for unwanted pages and popups on your Mac, but do not let them tempt you to click the "OK" button. Even software ads like MacKeeper appear to be genuine in letting you know their software is there to help, but even the way these companies detect that you are using a Mac, and push notifications to you with threatening tactics is unethical and unsavory. Don't let them convince you to engage in their marketing schemes!
The best approach is to click a cancel, or "no thanks" button. If this option is not present, you best choice is to close the window or quit the application. You can quit or force quit an application from the application icon on the dock to escape the pushy adware pages.
Do not call the 800 phone numbers they offer or allow the company to remotely control your computer. These companies have even been known to identify themselves as "Apple Support". They are not affiliated with Apple. Pop up ads in never a way that Apple promotes their support.
If a malware/adware advertiser has affected your computer, call MacTEK to set an appointment. These "infections" can be easily remediated and there is no need to send your computer away for repair.
Last note, this type of concern is another good reason for every user to keep a Time Machine Backup of your computer. You can easily restore your computer account to before the infection.
