When it comes to keeping your computer safe from hackers, it used to be that Apple's Macs were considerably more secure than Windows PCs. That's been changing and, in fact, researchers have found five times as much malware on Macs this year than in the previous five years.
So, it's important to beef up your Mac security efforts. That's especially true for software programs that are notoriously buggy.
One of the most problematic programs is Adobe Flash. The graphics program has been bogged down with malware attacks for quite a while. In fact, if you can get away with not using Flash, you should get rid of it.
However, there's handy add-on that gives you the flexibility of using Flash when you need it, without installing it and uninstalling it each time you do. It's called ClickToFlash, which can be used on your Mac's Safari Web browser.
With ClickToFlash, your Adobe Flash remains on your computer, but you keep it turned off when you don't need it. When you're watching a video, say a YouTube video, ClickToFlash will let you watch them in QuickTime, or the H.264 video format on your iPhone.
"Flash" will be visible, but grayed out. If you need to use Flash, just click on that grayed out font to turn it on. You can also set a "whitelist" of websites that you decide are OK to use Flash.
