Just got a Macbook for Christmas. Always had a PC before. Is there anything I need in terms of antivirus? I don't do much with my computers, but I will stream live sports and ufc ppv's. Not sure what kind of stuff I probably get from those sites, but figured you guys might be able to tell me if I need anything or not.
Thanks!
No platform is immune, but by far the most common issues have to do with web browsing, and since that's what you expect to be doing most...
1) Pop-up web pages disguised as system warnings... "Your system is infected, call this toll-free number for support..." Dire warnings like, "Do not restart your system or browser." It's all BS. You may be unable to dismiss the warnings, but under nearly all circumstances a force-quit of your web browser will fix it (Apple menu > Force Quit, or Command-Option-Esc key combination). Then, hold the Shift key while you re-open your browser - that opens a fresh browser session and "forgets" the page it had previously been on.
2) Adware - browser plug-ins and extensions that muck up your browsing experience. You may see (far) more ads than usual, search attempts bring you to an unwanted search engine, an attempt to go to a support web site or anti-virus provider may take you to the "competition," maybe your home page has been changed... Download and run Malwarebytes for Mac
https://www.malwarebytes.org/antimalware/mac/ This is run-when-you-need-it software, a fix-it tool for when you suspect a problem.
How do you get Adware? Downloading apps from the wrong source. Always obtain apps directly from the developer (or Mac App Store). Sometimes Adware is bundled in with an app you believe you need (ads for Mac cleaning and anti-virus apps are well worth avoiding). If you get a pop-up telling you, "To view videos on this site, download..." be leery. If the download is a well-known product like Adobe Flash, go to Adobe.com to download it, rather than trust the pop-up message to provide a safe download.
Keep up with your OS X software updates.
