SecureDossier – What is it and how to remove it? (Virus Removal)


SecureDossier by 6Loop Limited is a system cleaner and optimizer compatible with computers running Windows operating systems. Like other system optimizers for Windows, SecureDossier has a bad online reputation and is detected by multiple Antivirus engines as adware, a trojan, and potentially unwanted program (PUP).

Microsoft doesn’t like it

Microsoft does not approve of system optimizers such as this program and publicly states that they can be harmful to your machine. Using a system optimizer that promises to boost your performance and fix your registry can actually remove important files and change settings that keep your computer running smoothly.

Utilizes deceptive marketing tactics

SecureDossier is often promoted as something it is not in order to trick users to download and install it. For example, we found that SecureDossier was being advertised as a media player called FirePlayer. When we tried to manually download the executable file for FirePlayer we were actually tricked into downloading a file called SDOSetup.exe which is the executable file used to install SecureDossier.

Furthermore, Google Chrome blocked us from downloading SDOSetup.exe and stated that “this type of file can harm your computer.” We were able to bypass this restriction by choosing to keep the file as opposed to discarding it.

Misleading scans

SecureDossier employs the use of misleading system scans and diagnostics to cause fear, uncertainty, and doubt (FUD) and obtain customers and regular users.

SecureDossier add remove programs

SecureDossier scans your computer for cookies, browser history, startup items, installed programs, duplicate files, and items in the trash. When the scan is complete, SecureDossier will show results that suggest the programs you have installed on your computer and files you have saved on your computer are issues. The action to fix these issues is to uninstall the programs or remove the files; However, the SecureDossier program was unable to remove files at our request.

This is a concern because files on your computer do not impact the performance of your computer and the programs you have installed on your machine are not essentially considered “issues.”

It’s malware

According to VirusTotal, SecureDossier is recognized as malware by reputable security programs including DrWeb who detects the program as Trojan.Siggen7.59319 and Webroot who detects the program as W32.Adware.Gen.

Programs that utilize deceptive marketing tactics and misleading scans are often recognized as malicious. So it’s no surprise here that SecureDossier is recognized as malware by multiple Antivirus engines.

How to protect your computer

Once you have uninstalled SecureDossier and scanned your computer for malware with Malwarebytes and HitmanPro, consider these best practices to ensure that your computer is protected from future threats.

Use Antivirus with real-time protection

Antivirus program with real-time protection can stop emerging threats and hackers from gaining access to your computer or mobile device. Antivirus programs can remove malicious files that are already on your computer, prevent your programs from being used against you, protect you from malicious websites, and stop known and unknown ransomware attacks.


Use a VPN

A VPN creates a private tunnel to keep the eyes of eavesdroppers and hackers away from your private data while you browse the web. With a VPN, you become anonymous and no one can determine who you are. Your data is encrypted and your web activity cannot be tracked.


Ignore email messages from people you don’t recognize

Ignore email messages from people you do not recognize or are not expecting a message from to avoid malware from spreading onto your computer or mobile device. Email messages often contain malicious links and attachments that can be harmful to your computer. In fact, email spam is one of the most common ways that malware is spread.
