Apple OS X users love to boast to the virus-ridden Windows peasants that OS X is immune to all viruses and adware. But, sadly, that just isn’t true. Apple OS X Users Aren’t Safe Either. But really no one is safe from the grabby hands of viruses.
OS X users do have a bit of an advantage by running a UNIX-based operating system, which is able to lessen the powerful viruses that Windows is so harshly attacked by. But the menacing and computer-breaking viruses are not the ones to worry about in this case.
Apple OS X users are mostly attacked by the very annoying and pesky type of bad computer stuff: bloatware/adware. This is the bad stuff that is able to get into your browser and see what you are doing around the internet, while stealing your passwords by logging everything you type.
But how do I get this adware on my computer? Well, adware 
is usually downloaded by piggy-backing on the installation of other programs. You may remember have to click ‘Next’ through multiple different programs just to install your intended program. You then see a random program on your computer along side your intended program – Adware.
The accidental installation of adware/bloatware while installing your intended program is something that most definitely affects both operating systems. And in some cases, OS X adware is more effective because of the mindset of most OS X users that they are immune.
