I have a non Apple laptop and use Norton in it. Anytime I have looked at getting a virus protection for the MacBook I have been told it doesn’t need it as the OS has one built in. Am currently using the MacBook more and more and was wondering if this this opinion still held true or whether it would be worth installing the Norton on it as well? Any thoughts would be appreciated.
This is one of the advice which depends solely on your usage and situation. Windows is simply the most popular OS being used in personal and businesses and therefore the most exposed to potential attacks. So subscription based anti-virus and malware program is a must if you use Windows, not only to protect the host computer from infection, but other internet appliances like your router, iPhone, Android phone and even your Google Mini or Amazon Dot for malware infection. Malware infection is NOT only limited to your computer anymore, but now can infect your router or your IoT devices.
If you look at it in terms of how virus attacks had morphed, today's virus attacks are mainly targeted for monetary and financial gains, but not through a computer host. A computer host is simply the carrier of the virus or malware to the designated target, which is your router, your router modem or your old phones. Which means that the so called "FREE" Malware and Adware program you installed on your Mac is fine for your Mac or PC alone, but offers zero protection to your router, router modem and IoT devices, because the host software aren't meant to protect other devices. They are designed, unlike in the past for pranks and for destroying your system, to spying your personal life, personal finances and or place your computer hostage for ransom as had many businesses had succumbed to because they failed to encrypt their business database or encrypt their personal data. Encryption plays havoc on Macs when you want to customize your T2 secured Macs to boot to an external drive or keep an older OS for compatibility issue.
Why did those businesses fell prey to ransom ware when they had supposedly the best virus and malware protection. Well, that is because businesses also allow public WIFI and office use of their employees' WIFI capable phones and laptops. Despite the attempts to secure with Malware and virus protection software, they completely ignored the router and your router modem because they assumed they are not targets for attacks. But "Malware" do target your router and your router modem, because once they get a hold of your router and router modem, they will be able to re-route your DNS server or simply sniff your packet for your private information, giving you a false sense of security that everything is fine when in fact, the hackers to infiltrate the corporate servers through hacked routers. A number of small businesses or even some large business save money and buy off-the-shelf routers that receive very little in terms of firmware updates to get the latest security patches.
A good router should receive the latest security patches on a monthly or semi-monthly basis. Asus, Synology, PepLink, Ubiquity products and a few others do. Some like Asus include AI Protection Pro scanner via Trend Micro that scans sites for malware, viruses and ranson ware and adware and block them including this very site -- Macrumors.com which contained a number of adware and tracking stuff. Obviously through fully secured router and via VPN, it is very difficult for me to visit this site and therefore and while this is a safe site to visit without any malware infection, this goes to show to you that it does not even take any malicious site to infect your system because your router and security gateway weren't up to snuff to detect through Deep Packet Inspection the malicious activities it is being conducted in the background that even Avast Free or Malwarebytes could not detect. To me, these software just offer some nice assurances that you are being protected, but in fact, offer nothing more than just assurances.
To protect yourself from full malware protection, you need a router and gateway security system that will help filter them out. The only caveat to this is that, you simply can no longer browse 90% of what's on the web, including Facebook, Whatsapp, Instagram, Google, Microsoft Hotmail etc as they are all tracking your activities and therefore spying on you. So you see, I run 2 systems at home. One is public where I can full access the web and I am being tracked, tagged and potentially infected with malware that can attack my router and I also have a more secured router and security gateway that protect my Macs from any tracking, spying and tagging. It was an eye opener of what my security gateway was telling me in terms of malware infection and possible malware from sites that aren't even malicious! Sites that you would think is completely and utterly safe!
So it all comes down to this. What are your needs and how secure you want to be on the net and your privacy? No computer system is secure and free of virus and malware infection. No Malware software can provide full protection.
My best advice would be here.
1, Make sure your Mac is using the latest Mac OSX that still can receive the latest security updates
2, Running Malware programs like MalwareBytes gives it supervisory access. I personally never like giving programs supervisory access as it can access private information and phone home to use your info to compare to its database.
3, Always update your router with the latest firmware which contains the latest security patches. If your router is an older model, chances are it is easy for hacker to compromise your router. You will not know if your router is compromised! The only way to be sure is to schedule your router for a reboot maybe once a day at night to remove the router's malware. Or else buy a new router that offers monthly or semi-annual updates.
4, Don't go to un-secure sites without https especially if you are browsing at work. When you go to these sites and they realize you are on a corporate web link, they will exploit your system to infect your corporate routers or servers. Remember that today, your computer is simply a carrier to an infected target. The so called benign safe websites are the host of the malware. Malware software can only scan for signatures for your host computer, NOT for routers, iPhone and Android phones. The best way to scan for everything is to test the site's URL with
http://www.virustotal.com. This site will scan the site for every possible engine of infection.
5, Use a secured browser that offers some VPN service that masks your geolocation, ad blocking and malware blocking and inspection. When you do this, many websites will complain and or won't load. So it is basically a balance of wanting better security vs lesser security.
