Regardless of the bad actors' motivational reasons, it definitely does not bring any benefit to the user. In fact, sites like,, and many others are created to harm the user.

Note how all of the domain names are using words like “fix,” “repair,” “Apple,” and similar. This is done purposely in order to make scam more believable. Nevertheless, we can assure you that this scheme has nothing to do with Apple or authorized technical support services.

The fake pop-up message that users encounter on domain reads as follows:

Stay away from potentially unwanted programs by installing shareware correctly

Unlike malware, potentially unwanted programs are not deemed to be as dangerous. Nevertheless, consider a PUP like a tunnel that MIGHT connect you to malware infections, as well as money loss, or even identity theft. Therefore, it is best to stay away from unwanted applications in general.

PUPs are usually delivered via software bundling – a deceptive technique used by shareware or freeware authors. It often focuses on hiding the real list of the programs inside the installation wizard. Therefore, it is vital to handle the installation process correctly.

First of all, experts[2] recommend staying away from unknown sites (no HTTPS[3] protocol) and those that offer pirated/cracked software. Malicious executables can be disguised as anything, and deliver not only PUPs but also malware, such as ransomware. For example, many of the recent STOP ransomware variants were distributed via the illegal program site Crackithub[.]com.

Once you launch the installation wizard, make sure the app provides required documentation – Privacy Policy and Terms of service. When prompted, opt for Advanced/Custom installation settings instead of Recommended ones, and terminate all unwanted apps by removing ticks from pre-selected boxes.

Remove redirects by deleting adware from your device

To remove redirects and pop-ups, you will have to terminate adware that is hidden inside your system. Note that if you encountered the scam website accidentally, it does not mean you are infected with anything. It simply means that you got redirected to a phishing site from another one. Nevertheless, a scan with security software can confirm whether or not your device is dealing with any type of computer infections.

Alternatively, you can take care of removal with the help of our manual instructions below. These steps are straightforward to perform. However, once you detect the unwanted app, make sure you check these folders for any leftovers of the PUP: /Library/LaunchAgents and /Library/Application Support. After that, reset each of the installed browsers to make sure no redirects continue.

How to prevent from getting adware

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
