Prefs Secure-FAQ
What Is Prefs Secure?
The Prefs Secure threat is adware or browser redirect virus.
It may slow your computer down significantly and display advertisements. The main idea is for your information to likely get stolen or more ads to appear on your device.
The creators of such unwanted apps work with pay-per-click schemes to get your computer to visit risky or different types of websites that may generate them funds. This is why they do not even care what types of websites show up on the ads. This makes their unwanted software indirectly risky for your OS.
What Are the Symptoms of Prefs Secure?
There are several symptoms to look for when this particular threat and also unwanted apps in general are active:

Symptom #2: You have toolbars, add-ons or extensions on your web browsers that you don't remember adding.

Symptom #4: You see installed apps on your Mac running automatically and you do not remember installing them.
Symptom #5: You see suspicious processes running in your Task Manager.
If you see one or more of those symptoms, then security experts recommend that you check your computer for viruses.
What Types of Unwanted Programs Are There?
According to most malware researchers and cyber-security experts, the threats that can currently affect your device can be rogue antivirus software, adware, browser hijackers, clickers, fake optimizers and any forms of PUPs.
What to Do If I Have a "virus" like Prefs Secure?
With few simple actions. First and foremost, it is imperative that you follow these steps:
Step 1: Find a safe computer and connect it to another network, not the one that your Mac was infected in.

Step 4: Call your bank to change your credit card details (secret code, etc.) if you have saved your credit card for online shopping or have done online activities with your card.
Step 5: Make sure to call your ISP (Internet provider or carrier) and ask them to change your IP address.
Step 6: Change your Wi-Fi password.
Step 7: (Optional): Make sure to scan all of the devices connected to your network for viruses and repeat these steps for them if they are affected.
Step 8: Install anti-malware software with real-time protection on every device you have.
Step 9: Try not to download software from sites you know nothing about and stay away from low-reputation websites in general.

How Does Prefs Secure Work?
Once installed, Prefs Secure can collect data using trackers. This data is about your web browsing habits, such as the websites you visit and the search terms you use. It is then used to target you with ads or to sell your information to third parties.
Prefs Secure can also download other malicious software onto your computer, such as viruses and spyware, which can be used to steal your personal information and show risky ads, that may redirect to virus sites or scams.
Is Prefs Secure Malware?
The truth is that PUPs (adware, browser hijackers) are not viruses, but may be just as dangerous since they may show you and redirect you to malware websites and scam pages.
Many security experts classify potentially unwanted programs as malware. This is because of the unwanted effects that PUPs can cause, such as displaying intrusive ads and collecting user data without the user’s knowledge or consent.
