I guess I am just a tad shocked that people on a forum such as this think that: a.) there is a risk (for us) and b.) they need 3rd party software to mitigate it.
That's like thinking you are so much smarter than all other drivers and such a great defensive driver that you don't need insurance. It is bogus, naive thinking.
Are you seriously suggesting you are infallible?
That you are smarter than all the bad guys out there?
That you could never be fooled by a cleverly designed, socially engineered fake email or webpage?
That you are so self-disciplined that you could never, not even once, slip up and accidentally click on something you shouldn't?
That no legitimate site you visit could ever be hacked and planted with malware?
That an update for one of your trusted programs could never be implanted with malware by a hacker to the developer's site?
I could go on but hopefully you get the point. Most of us on this site are conscientious enough to prevent compromises - when we are paying attention. But I personally am not that focused every second of every minute of every hour I am on line every day.
Many of us use computers that have other other users - other users that may not be as disciplined as us. Many of us have kids and grandkids with pretty smart (and perhaps nosy) friends that might not be so trustworthy. Many of us have occasional house guests with wide ranges of skill-sets and "
security awareness" that use our computers or request network access.
There is some truth to what you are saying - especially these days with a fully updated Windows 10. If you are the only user of your computer and you stick to the legitimate sites, it is difficult to become infected. But difficult does not mean impossible. Having a good anti-malware solution is like having good insurance. You hope you never need it. But if (when!) you do need it, you want it to work.
