Like any computer, your Mac needs some clean up work done every once in a while. Before downloading a Mac cleaner software however, you should know that some Mac cleaners can actually make your Mac worse, instead of better!

Some reasons that you should be cautious of which Mac cleaner you choose, include downloading a virus, installing a program that works improperly, or by downloading multiple cleaning programs that will just add to the clutter on your Mac’s hard drive.

Why do you need to clean up your Mac?

We get it, your mac isn’t the top performer it once was. That is a solid reason for getting a mac cleaner to restore past performance.

Another thing is to consider is privacy and protection. Do you have viruses or injections on your laptop? Yup, a legit mac cleaner will help this, too.

Getting a Legit Mac Cleaner.

By getting the best Mac cleaning software (and not just a “one trick pony” apps) you’ll be able to optimize, speed, protect and un-clutter your computer pretty quickly.

But wait… is Mac Cleaner even safe?

The short answer would be yes. Mac cleaner safe and it does work. This app just like Antivirus, Firewall or Speed-optimization software people are using for PC (Windows, eww)

The only difference that a good mac cleaner does it ALL in one program. No more installing 5 different apps, each for its own purpose – maccleaner does it all.

Why do you even need an Antivirus software?

Mac owners (or Apple fans) answer to this question is usually “No, I do not need an anti-virus program for my Mac, because Mac’s don’t get viruses”. Although it’s true that Mac’s do not get viruses as often as Windows, but they do still get them!

In fact, there are new viruses popping up every day (and malware programs), that are directly targeting Mac computers!

If your Mac got exposed to such a virus in any way, you’d be happy you got a real Mac cleaner (which includes an anti-virus program) that will either block the virus all together, or locate and destroy it before it harms to your files and passwords.

Keeping your computer protected from malware and viruses, is not something all Mac cleaning software programs include. Therefore, finding a reputable, good-quality Mac cleaning software that includes advanced antivirus protection is VERY important.

Final thing before you use a Mac cleaner: Know what you’re downloading!

By downloading a Mac clean up software, you could actually be downloading a virus or malware program to your computer. In fact consider the names of the four most popular Mac viruses: MacSecurity, MacProtector, MacDefender, and MacShield. Each of them sound as if they will be a beneficial Mac clean up tool, when in fact they are all viruses that will corrupt your Mac’s hard drive, and steal your personal information.

So what can you do to be safe? Just remember that like with any computer, you should only download what you know is safe. To avoid downloading bogus Mac clean up software, you should be sure that the program is one that is recognized via awards, and other acknowledgments, and promoted as a good Mac clean up utility, by those in the computer industry.

Another sign of a Mac cleaner that may not be what it says it is, is that it will be offered to you completely for free. Therefore, one should consider spending a few dollars on a good Mac cleaning software program, which will help them feel confident that it is a legitimate program, and company. Purchasing a safe, and reliable program that will do what you need it to do, is definitely worth the price.

How to remove WARNING! MAC OS Is Infected from Mac?

What is WARNING! MAC OS Is Infected?

'WARNING! MAC OS Is Infected' is a fake error similar to Apple Security Alert, Apple Support Center - Attention!!, Apple Warning Alert, and many others. This error is displayed by a malicious website that users often visit inadvertently - they are redirected by various potentially unwanted programs (PUPs). These programs also deliver various 'malvertising' ads (pop-ups, banners, coupons, etc.), record information (mostly, about web browsing habits), and misuse system resources.

This error states that the system has been infected and that the malware must be removed and system repaired immediately. Users are advised that they must not hesitate to call Apple technical support via the telephone number ('1-844-658-5859') provided. Certified technicians then supposedly guide users through the malware removal process. Bear in mind, however, that 'WARNING! MAC OS Is Infected' is a scam. This error is fake and has nothing to do with Apple. In fact, cyber criminals claim to be certified technicians and attempt to monetize their services that are not needed. In addition, these people often trick users into granting remote access to their computers. Once connected, cyber criminals stealthily install malware and/or change system settings. Then they claim to detect additional errors and offer further help for an additional fee. Therefore, we strongly advise you to ignore 'WARNING! MAC OS Is Infected' and to never call the aforementioned telephone number. This error can be removed by closing the web browsing or rebooting the system. Be aware that some malicious websites and PUPs mine cryptocurrency or run other unwanted processes in the background. They misuse system resources without users' consent, thereby significantly diminishing overall computer performance. Potentially unwanted programs are also known to gather various information that might contain personal details. This data is sold to third parties. Furthermore, PUPs often deliver malicious ads using various tools that enable placement of third party graphical content on any site. Therefore, the ads usually conceal underlying content, thereby diminishing the browsing experience. Malicious ads may also lead to rogue websites and/or execute scripts that download and install malware. Therefore, even accidental clicks can result in high-risk computer infections. For these reasons, we advise you to uninstall all potentially unwanted programs immediately.

As mentioned above, 'WARNING! MAC OS Is Infected' shares many similarities with dozens of other fake errors. Each and each one claims that the system is damaged , however, these false claims are merely attempts to extort money from unsuspecting users. Potentially unwanted programs are also very similar. By offering various 'useful features', PUPs trick users into believing that these programs are legitimate and useful, however, that all potentially unwanted programs only generate revenue for the developers. Therefore, only very few give real value for regular users. Most merely promote rogue websites (unwanted redirects), deliver malicious ads, gather information, and misuse system resources. These programs pose a direct threat to your privacy and Internet browsing safety.

How did potentially unwanted programs install on my computer?

Research shows that some PUPs have official download websites, however, most are distributed using a deceptive marketing method called 'bundling', and via the aforementioned malicious ads. Therefore, users often install PUPs inadvertently or PUPs stealthily infiltrate their systems without permission. Bundling is stealth installation of third party software together with regular apps. Developers hide bundled programs within the 'Custom/Advanced' settings or other sections of the download/installation processes. Many users are careless during download and installation - they rush and skip steps. In addition, many users click various ads. This behavior often leads to inadvertent installation of potentially unwanted programs.

How to avoid installation of potentially unwanted applications?

The key to computer safety is caution. Therefore, pay close attention when downloading/installing software and browsing the Internet in general. If possible, select the 'Custom/Advanced' settings, carefully analyze each window of the download/installation dialogues, and decline offers to download/install third party programs. Bear in mind that third party download/installation tools are monetized by promoting dubious programs (the 'bundling' method). Therefore, we recommend that you avoid using such tools - your software should be downloaded from official sources only, using a direct download link. Most malicious ads appear legitimate, as developers invest a great deal of time and money into their design, however, these ads are distinguishable for their redirects - most lead to survey, adult dating, pornography, and other similar sites. Therefore, if you encounter this type of ad or website, immediately remove all suspicious apps and browser plug-ins.
