Mac Tweaker – a rogue system optimizer that might leave you disappointed

Mac Tweaker PUP

Mac Tweaker is advertised as an optimization tool that can clean and optimize Mac OS X system 10.7 & above. Similarly to MacKeeper, Mac Optimizer, Mac Mechanic and many others, this questionable application infiltrates users’ machines without permission. Thus, it falls into potentially unwanted program[1] category.

SUMMARY
Name Mac Tweaker
Type Potentially unwanted program
OS affected Mac OS X 10.7 and above
Main dangers Wasted money on full license, important file deletion, personal information disclosure
Distribution Bundling, online advertisements or official website – hxxp://mactweaker.com/
Elimination Download and install Reimage. Manual method also available

As soon as the unwanted app infests your system, it performs a computer scan. You should not be surprised that, according to Mac Tweaker, your system is affected by many issues that need to be addressed. As soon as you proceed and click “Fix” however, you are prompted to buy a full version of the program.

A licensed version is subscription based and costs $39.95 every six months. You are also offered additional software that costs another $19.95. The service is expensive, especially when you combine it with questionable functionality.

If you proceed with the purchase, you are asked to provide personal details, including name, email, phone and bank information. Please read the following from developer’s EULA:

7.2. You acknowledge that Mac Tweaker collects certain information regarding the users of the Software, including certain personally identifiable information. You hereby consent to Mac Tweaker for collection and use of such information, and agree that Mac Tweaker's collection and use of such information will be governed by Mac Tweaker's Privacy Policy

We highly advise refraining from this offer as the personal information might be used for questionable purposes (typically marketing); however, you can never know when your data might be misused, especially when payments are handled by 3rd parties, too. Thus, do not trust this program – remove Mac Tweaker immediately.

The main problem with fake optimization tools is that all of them have a similar function: they mostly enter users machines through software bundling or advertisements, perform the scan, find hundreds of “issues” and demand payment for the alleged fix. The whole scheme is incredibly shady. Therefore, some people might call it Mac Tweaker virus (although it is not).

If you want proper tools to protect your computer, select reputable security software, like Reimage. Not only can it help you with Mac Tweaker removal but can also detect other PUPs or even malware. Furthermore, junk files,[2] trash, logs and other issues can be eliminated manually – for free.

Ways rogue software invades users’ machines

The suspicious application can be distributed in two ways – downloaded and installed intentionally or installed together with other free software. As the PUP performs scan instantaneously after installation, confused and scared users might proceed with the full license purchase.

Therefore, do not let questionable applications enter your Mac OS that easily – be attentive while installing freeware. The most important thing is not to rush the installation while clicking “Next” button without looking. By doing so, you might skip essential steps. Thus, read installation instructions carefully and always opt for Advanced or Custom installation mode. Make sure you deselect any pre-selected tick marks by add-ons, toolbars, optimization tools, etc.

Uninstall Mac Tweaker from your Mac and save your money

Security experts[3] noted that fake optimization tools are not useful for your computer and should be avoided in the first place. However, if you noticed that your system is being scanned out of nowhere, remove Mac Tweaker at once.

You can remove Mac Tweaker manually by using our guide below this article. Do not forget that you have to eliminate all related files in the libraries. Also, we do not advise picking this method if you are not that computer-savvy individual.

You can also opt for automatic Mac Tweaker virus removal – it will only take a few minutes. Please pick one of the programs mentioned below, install and run a full system scan. If you recently installed free software and obtained Mac Tweaker, it is highly likely that you have other PUPs installed on your system, like a browser hijacker or an adware program. Security software will detect all of these unwanted programs and eliminate them for good.

You can remove Mac Tweaker automatically with a help of one of these programs: Reimage, Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus, Malwarebytes Anti Malware. We recommend these applications because they can easily delete potentially unwanted programs and viruses with all their files and registry entries that are related to them.
