DownloadFour signs you need internet security for Mac.
Scary virus alerts everywhere online
Next time you see “remove 5 viruses now” on the web, just close the tab. It’s fake. Browser functionality can’t detect anything malicious. Remember, only specific security apps like MacKeeper can spot viruses.
You often connect USB drives to Mac
Sometimes transferring your documents or photos may end with a nasty surprise. Running a Mac security scan is a good idea. MacKeeper can scan a specific device or folders and stop the virus before it spreads.
Annoying ads drive you crazy
Keep seeing intrusive ads? Chances are you Mac is infected with adware generating tons of popups. The best way to check it is to scan your Mac with adware cleaner.
You can’t find your Mac
Who knows why your Mac went lost. Well, MacKeeper knows. Use the Track My Mac phone app to see your Mac’s location and lock it remotely. What’s more, you’ll see a snapshot of whoever entered the wrong Mac password.
