If you encountered a webpage alleging your Mac is infected with some kind of ick, just close that web page. Read Phony "tech support" / "ransomware" popups and web pages for a description.
On the other hand if you have a Notification (a banner or alert at the upper right of your screen) then you installed adware. The solution to that problem is to find out what it is, and delete it. Read below.

Navigate to the following folder, and post its contents in a screenshot.
~/Library/LaunchAgents
To open that folder, copy the entire line above and paste it in the Finder's Go menu > Go to Folder... field. Make it look like this:
... and click the Go button.
A Finder window will open. Take a screenshot showing all that folder's contents, and post it in a reply. To take a screenshot read the Appendix in the following User Tip: Writing an effective Apple Support Communities question.
Usually, there is nothing in that folder so don't be surprised to find it empty. The reason for starting with that folder is to eliminate other potential causes before proceeding with steps that will identify and eradicate whatever is affecting that Mac.
There will be additional instructions to follow and this is just the first step.
For a description of how this may have occurred, how to avoid it in the future, and for Apple's recommended actions read How to install adware.
