As detailed above, Mac users should install antivirus software on their computer just like Windows users. In fact, antivirus alone would have prevented most Mac infections listed above.
There are many options to choose from here.
Java is a cross-platform environment for running applications or "applets". If you didn't know what Java is, you don't need it on your computer. Most websites don't even use Java applets anymore, so you won't miss it. Plus, according to the security company, Kaspersky, Java has been the cause of half of all attacks affecting computers. The problem lies in the fact that Java doesn't check if the content it is playing is secure, so it creates a perfect place for hackers to code in malware.
The instructions on how to remove Java can be found here.
Do not disable Gatekeeper
Even though malware can sneak past Gatekeeper with a phony Developer ID, enabling it will not hurt. It would also be best to limit downloading applications from third parties all-together. If you can find what you need on the official AppStore, it would be safer to get it from there.
Backup all your data to an External hard drive.
Time Machine is great, but to ensure that data is really secure from hackers, you can disconnect it from the network entirely. Using external hard drives is the only sure way to keep your data out of the hands of hackers; unless they are able to steal the external device itself.
It goes without saying that users also have to take some responsibilities for their own security. This means being careful about the websites you visit, and what links you click on, and what you download. Also, watch out for suspicious looking emails and attachments. It seems obvious, but even Mattel recently fell for a $3 million phishing scam, so it can happen to anyone.
If you are at all suspicious of a website, do not chance it. The easiest way to get infected with malware is to indiscriminately click on any link and open any email, regardless of how questionable they seem.
As Macs become more popular, users have to learn to protect themselves the same way Windows PC users do.
It's only a matter of time before Mac users have to deal with being attacked, and they are not going to have the tools in place to deal with hackers. Since Apple has not invested the time, energy, or intellect that Windows has with malware prevention and security, it actually leaves Macs more vulnerable to attacks.
Pedro Bustamante, Vice President Products & New Technologies at Malwarebytes says, "Cybercriminals are on the lookout for easy targets, and nothing could be easier than capitalizing on under- or unprotected Mac systems shrouded under a false sense of invincibility."
So, it might be a good idea to take measures upon yourself before the malware hits the fan.
