Hi, While it is true that you must be careful and follow your intuition to not download a file from "infect-your-mac-and-have-to-pay-a-ransom-today.com", not all sites that seem reputable, or even have tons of great reviews will not try to slide in some adware or whatever else onto your computer, and if our computers are just so amazing and "there is NO software that will protect you from downloading from questionable sites except your own awareness", then why is it that I have gotten notifications from Kaspersky on both my MacBook Pro, and many PC's that I was either installing adware or something else that could harm my computer on, or a notification that says that the app just quarantined a dangerous file. I have trusted only the computer's built-in protections before, and all that got me was some program controlling my computer, and I could not close the browser because I was stripped of my ability to control my own computer. All I could do is keep clicking the Chrome open new tab button which gave me one of those fake support numbers that you call while your computer is further destroyed because you were foolish enough to think that the page is from your computer manufacturer. That was on a computer I was issued from my school. On the login screen every time you turned the computer on, there was a notice you had to agree to, and one of the terms was that you will not modify the "build in protection software" or install your own. All it came with is Windows Defender. Not comparing Windows Defender to Mac security, but at least Windows has a built-in app that you can scan in interact with. Not that it worked well, because the only time it ever worked is when I had already removed a program manually that I had realized was adware when Windows Defender said "we have detected adware on your computer". Point being, that build-in protection is not always the best, and even the U.S. Government uses McAfee security just to be safe, on even the most unthreatened computers, like ones that sit in a room all day, awaiting to be leased to a lower level employee who's computer has no dangerous or treating files to government security. On the other hand, I have been protected from many unsafe things being downloaded onto my computer because Kaspersky stopped the download. Thanks Kaspersky. So, save yourself the money, and convince yourself that your computer is invincible, but if you download things from the Internet, you might not want to let your state of being a fanboy or fangirl for your computer manufacturer put you at risk of losing everything. If we didn't need (or if it was not at least a good idea) to have any protection software, then why do they exist. I use one, and despite many baseless accusations of protection software being "bloatware" not one person is mentioning any proof because of experience that any protection program has just slowed their computer down. I bought my MacBook Pro and lived without any protection for about a week, (at the time, I had a Kaspersky subscription, but had not yet installed it on the Mac) and after I installed a not-so-reputable piece of software from a fine site, that was slipped in with the download that I wanted, I downloaded and activated Kaspersky on my Mac, and the computer is not a second slower than it was when it was brand new. Only at 11:58 to 12:00 PM does the fan start making a little noise when I am working the computer hard, and Kaspersky runs its scan that I programmed it to do every day. Say all you want, but there is a difference between people saying things because they want to hold up a failing point to not look bad and actual experience. If anyone here has had a negative experience with a protection application, I am more than happy to hear the story, but just as no two people are the same, neither are two protection programs, and neither are any two different computers used with the software. Your computer may be slow because you don't use it within a reasonable measure, and push is harder than its specs provide for, then you blame it on the software being bloatware. I know from personal experience when I was using a Lenovo G50-80 as my main computer and when my needs increased, I didn't upgrade, then just complained that it was a bad computer. Not how it works. Protection software is not for everyone, and I did not say it is, but it can be a good idea for many people if you have the money to spend (or have a free program you trust, but that's not always advisable) and want to be safe in the event that something happens. Especially in my family where we trust our tech to hold so much of our lives, there is no point in risking losing it all when you can just use a not overpriced at all program and not worry about a thing. We have many computers that run slow because we have had them for a while and take them many places without cleaning them because we don't have all the time in the entire world (which is why I read very little of that long and fluffy article. If you want people to believe you or think about your point, don't make them hunt for facts to prove your point. Be your own advocate, because after all, it's your job to prove your point, by explaining the facts, not having someone read the fluff. Not my job. I'm trying to prove a point to). Most people don't have 50 hours to spend on cleaning a computer (I exaggerate), but we do our best to not be bad computer owners, so when it is time, we usually just upgrade, and everything is fine again. Computers slow down when you work them harder then they are supposed to be worked, and that is why using another non-Chrome browser on a PC, for example, has become a sad necessarily thing for me, because Chrome unnecessary pushes a computer, unlike Safari for Mac. A computer used properly with or without protection software will not bloat your computer. So, use your computer correctly, and you'll be fine. Have a good day. Luke
