Is Cleanmymac Worth It

Theres a very good reason why CleanMyMac built up an enviable reputation over the past four years and this version will only further enhance that.

Automatic Cleanup uses an intelligent algorithm to suggest files that are 100 percent safe for removal.

One of the reasons Ive come to prefer CleanMyMac as a cleanup utility is its Safety Database, which whitelists important files so you dont accidentally wipe them from your system.

Avoid Fake Updates Or System Tools

Malware usually looks like a legitimate update. Typically this is offered via a fake warning dialog box while youre browsing. Fake updates for the Adobe Flash Player browser plugin, or fake antivirus/system optimisation apps, are a particularly popular vector of attack.

Note that Adobe ended support for Adobe Flash on 31 December 2020, so if you are invited to download the Flash Player dont do it!

What Is A Startup Disk

A startup disk, as taken from Apple Support article, is a volume or partition of a drive that contains a usable operating system. Still confused? Lets break it down for you.

Your Mac hard drive consists of disks . Each disk has your Mac data on it, which consists of your operating system, applications, etc. Most Mac users have just one disk but power users may have two or more.

Lets look at an example of a Mac with only one hard disk:

  • Your Mac’s hard drive is 500GB.
  • It has one “disk” on it, so all 500GB of storage is on that disk.
  • The disk has an operating system , and user data .
  • And since you only have one disk, this is your startup disk: all 500GB.

A Mac with two disks will have the storage divided between them. The Mac drive with the OS on it is the startup disk while the other drive is just used for storage of files. Its possible to have multiple startup disks, but most Macs will only have one. And for proper disk cleanup on Mac, all drives are just as important.

How To Detect Malware On Mac

Malware is not always immediately obvious, but there are red flags to look out for. Be wary if your Mac displays any of the following behaviors:

  • Your Mac runs unusually slow
  • It heats up even when you’re not doing anything that would use lot of processing power
  • Your Mac hangs randomly or apps crash
  • Your Mac behaves in a way it doesn’t usually

If youre concerned, you can do a bit of investigative work using your Mac’s built-in Activity Monitor tool. Click on Spotlight to search for it. Once it’s open, you can see a list of all the programs and processes using processing power on your Mac. If there are processes that you don’t recognize using lots of resources, that’s a sign that malware may be present.

Top tip. Even if you suspect malware, it’s unwise to delete any processes until you’re sure what they are. Developers of legitimate programs don’t always name processes in a way that makes it clear what they are. Try searching on the internet for more information first.

Disable The Invisible Agents

Some small supporting applications never show up in the Login items. They are called the Launch agents and may as well be hacked by viruses. You can find them with the universal Mac cleaner, CleanMyMac. This app is notarized by Apple, so you are safe using it.

If you have a recent backup of your data from before your Mac became infected, you can use that to copy data from after you re-install. If not, youll need to back up important files now but scan them with an antivirus tool first to make sure theyre not infected.

    Do I Need An Antivirus For Mobile

    Yes, you also need antivirus protection for your mobile phone! It should come as no surprise, but mobile devices are hacked just as often as computers.

    Android-specific malware has been on the rise in recent years, with huge ransomware and spyware infections affecting millions of users. If youre on Android, you need to get a malware scanner that can also protect your information online with features like a VPN, a Wi-Fi network scanner, and a password manager. Norton is my favorite Android antivirus especially because it scans apps for malware before you download them from the Google Play Store.

    For iOS users, there arent as many risks iOS is built with secure sandboxing, so theres no way for a malicious file or app to make changes to your device. However, iOS users still need to worry about unsafe Wi-Fi networks and phishing sites which can steal data, in addition to the very real problem of iPhone theft. McAfee is the best iOS security app Ive used in addition to phishing protection, a Wi-Fi scanner, and secure vaults for photos and videos, it also has excellent anti-theft features which include a remote burglar alarm, automatic selfie capture, and remote data wipe.

    Yes, malware can go undetected.

This means that a vast majority of malware infections go undetected. There are several reasons for this. First, antivirus software is not perfect and can miss some types of malware. Second, even if antivirus software detects malware, it may not be able to remove it completely. Finally, some malware is designed to avoid detection altogether.

    Delete Large And Old Files

    It has always been a rule of thumb among computer geeks, that you should keep a minimum of 15-20% of free space on your main hard drive. This is just a rough estimation, but the more free space you have, the faster your Mac works. A computer magazine once performed a test on this, which concluded that the difference in speed can reach as much as 35%. If you work with heavy graphics or video rendering, even more free space is recommended.

    How to have more free space? Delete large and old files.

    The first way is totally manual and requires you to find them one by one, while for the second way, you just need to make two clicks and CleanMyMac X will do the job for you.

    How to clean up Mac with CleanMyMac X:

  • Launch the program.
  • Review the details, select what to clean, and then click Clean.

  • Open a Finder window.
  • Ctrl+click on an application.
  • Select Show Package Contents.
  • From here, go to Contents > Resources and look for files ending in .lproj. These are the languages your app has just in case you want to use it in another language, like Spanish . Drag the ones youll never use to the Trash.

    Again, a safer alternative to this would be to use CleanMyMac X. It gets rid of all of them with a click. No digging through application folders, just a cleaner Mac.
