As long as you update your software, and do not visit shady websites, you should be fine.

 

To update your software, go to Apple icon, click software update, and let it update everything.

If you see Yosemite free upgrade, then you should upgrade as well.

 

Mac OS X comes with XProtect beginning from Snow Leopard, it is like a signature-based antivirus that updates daily. You will not know its there unless it finds a malicious application. 

 

Also, by default, you will not be allowed to open applications that are not codesigned.

I recommend that you do not disable it, and if you really have to use an application that is not codesigned (very old applications are not codesigned), then right-click and then click open, then it will still warn you that it is not codesigned, but it will also have an open button

 

If you changed this settings, then turn it back on by clicking Apple icon > System Preferences… > Security & Privacy > General tab

 

Under "Allow applications downloaded from:" choose the second option "Mac App Store and identified developers"

 

If you have Safari, then it will warn you about fraudulent websites. Do not visit that website if Safari identifies it as fraudulent. Chrome also checks for fraudulent websites.

In addition to what has already be said, I will note that Mac OS X has a pretty good firewall already built into the OS.

So, generally, you don't need anything else.

If you are the type who wants to go the extra step, then there are anti-virus programs that you can use, including free ones. Personally, I use VirusBarrier on my Macs. Many Mac users will say that is a waste of money, but it gives me the "warm fuzzies" (even though I know it is likely not needed), so I consider it worth it.

I was going to warn about the double-dot trick, but I checked on the double-dot trick (which worked so well in windows), and I figured out something interesting:

 

If there is an application:

Nameofprogram.app

And you have file extensions hidden, you will see it as:

Nameofprogram

 

If, however, you have an application:

Nameofprogram.anyfakefileextension.app

 

Then it will show the full extension

 

That said, its not completely foolproof as this could confuse people:

Nameofprogram,anyfakeextension.app to Nameofprogram,anyfakeextension

 

But, if you download an application from the internet, it will ask you if you are sure you want to open an application you downloaded

 

Clever! The double-dot trick doesn't work!

If you choose in Finder Settings -> Advanced to show all extension the double-dot trick does not work because the System shows the double-dot too = NameOfProgramm..app for example.

Yes (and that's how I set it up in Windows), but if you do choose to hide file extension, you will be safer than in Windows (I did send feedback in Windows 10 feedback app so that they might add it in Windows too) if you choose to hide file extension.
