You can protect your Mac from malware by following three simple rules. First, keep your Mac up-to-date. Second, only download from sites you trust. Third, stay informed. This videos shows you how to accomplish each of these steps.
Hi, this is Gary with MacMost Now. On today's episode, let me show you the three things that you need to do to keep your Mac safe from Malware. So, to keep your Mac safe from Malware, there are three things you need to do. First, is you need to keep your Mac up to date. Second, you need to make sure you only download from sites that you trust. And, third is, that you need to stay informed. So, to keep your Mac up to date, the main thing you need to do is go to the Apple menu, and use software update. And this will then check the Apple website for updates to Mac OS X and some of your Mac core applications. Now this should be going on automatically. You can check by going to system preferences and then clicking on software update. And here you can see, it checks for updates weekly , you can change that to daily for even quicker updates, and check off download updates automatically. Now, Mac OS snow leopard already includes the ability to check for and remove Malware on your Mac. Now, in order to do this it needs the definitions for the Malware. These are descriptions of what pieces of software are Malware. Now, the new security update that was out this week will check for the latest trojans, like say, Mac defender, so it is important that you have that security update. Now, the security update will check daily for new definitions of Malware. Matter of fact, if you go into system preferences under security under general, you will see the item, automatically update safe downloads list. And this, as it describes it right here, will look daily on Apple's website for new definitions of Malware to protect you against. Now, the security patch that is for Mac OS x.6.7, if you have something even newer than that in the future, then it will already include this security patch. Now, it is not enough to use just software update, because many of the applications that you've downloaded would also need to be checked for updates. Sometimes, these applications have their own ability to check for updates every time you run them, other times, you have to go to their website to check for updates. The second thing is, only download from sites you trust. For example, the Mac app store, or directly from developers like Adobe or Microsoft. Be sure you are actually downloading from the developers site, and if you don't know about the developer or the application, just do a simple Google search of that site, that developer, or that application, and you'll quickly determine if there is anything bad about that software. It'll be all over the internet. It is just good to do a check like that before downloading. And try to avoid bit torrent. Bit torrent is great technology but for downloading software, it is very difficult to determine exactly where the application is coming from. Also, in Safari, you want to go to Safari preferences, and under the general tab, you want to uncheck open safe files after downloading. And, this means, when you download something, it will just go into your downloads folder and won't automatically perform any actions, like opening or running. You will have to go to your downloads folder yourself and do that, which is a good security measure. And the third thing is to keep informed, which is very easy, because there are tons of websites that cover technology news, and tons of them cover Apple news specifically. So, pick your favorite one, and follow the news there. You can see a list of some of the top news stories at MacMost.com, and this would definitely include any new Malware threats. You can also use technology, like Twitter, Facebook, Podcasts, RSS feeds, just to follow the news coming out from any of these different news sources. Now, this may just be annoying if you aren't really interested in Tech news, but it's really important to stay informed. Otherwise, it's kind of like driving without looking where you are going. There's Malware out there, and if you are going to be using the internet, downloading software, and connecting to networks, you want to make sure you stay informed and keep an eye on what's ahead. Now, there's a new section of MacMost.com, MacMost.com/virus-and-malware, and this is where I'll keep things up to date about what threats are out there, and how to protect yourself against them. So, you may want to bookmark that as well. Until next time, this is Gary, with MacMost Now.
