Macintoshes don’t have the same problems as Windows computers with malware or adware, but that doesn’t mean they are immune. The attacks are different on a Mac, but just as annoying. Luckily, there are a few ways to remove unwanted Mac programs and prevent them from coming back.
The most popular infections I see in the wild are Genieo and
Once the problem software is on the Mac, Safari or another browser’s search engine changes and ads are injected. Sometimes the computer isn’t infected, but an intrusive ad pops up and prevents the user from surfing. These ads either take advantage of the Mac’s resume feature or use a JavaScript that prevents Safari from going further.
Some of these infections start as a Safari ad that won’t go away until you click a link or call a special number. The window might claim you are being watched by the FBI, like PC Ransomware. A few of these ads will start talking to you. Don’t fall for that scam. To get Safari back in order, first you’ll need to force quit Safari.

ClamXav v2 still supports OS X 10.6.8+ and will continue to do so until v3 is released (no projected date). I'm not aware of any other current A-V software that still does. That being said, those pop-ups about being infected are not due to anything on your Mac.

Apple has its own guide for removing Mac adware, but it’s hard to follow and covers just the operating system and Safari.Mac infections don’t usually come from the same sources as PC infections. They’re unlikely to be attached to an email or embedded in a
The most popular trick I see is an ad that convinces the user that Adobe Flash Player is out of date. I almost fell for that trick once. My Mac warned me before I installed it.
If you need to download software for your Mac that isn’t available in the App store, surf directly to the manufacturer’s website. Avoid searching for the product name since that may bring up ads. Search for the manufacturer and then find the product on their website. As an example, instead of searching for Adobe Flash Player, search for Adobe.
Apple’s Antivirus is Built-in: Apple’s Xprotect keeps your Mac from getting infected most of the time. It updates itself when Apple updates the MacOS.Scamzapper is a Safari Extension designed to prevent ads from locking up the browser. It blocks those JavaScript windows that prevent the user from moving forward in the browser. If you or someone you know keeps getting hit by those ads,

Thirdly: malware!
There are many forms of ‘Malware’ that can affect a computer system, of which ‘a virus’ is but one type, ‘trojans’ another. Using the strict definition of a computer virus, no viruses that can attack OS X have so far been detected 'in the wild', i.e. in anything other than laboratory conditions. The same is not true of other forms of malware, such as Trojans. Whilst it is a fairly safe bet that your Mac will NOT be infected by a virus, it may have other security-related problem, but more likely a technical problem unrelated to any malware threat.
