SecureDossier Unwanted Application
Written by Tomas Meskauskas on (updated)
What is SecureDossier?
SecureDossier is a program that supposedly allows users to optimize their computers by cleaning drives, improving system performance, and protecting them while browsing the web. Note that many people install this program on their systems unintentionally.
SecureDossier is categorized as a potentially unwanted application (PUA), since developers promote it using the "bundling" method (it is often installed together with other software).
One of the programs used to promote SecureDossier is called FirePlayer - SecureDossier is included (bundled) with FirePlayer's installer. When opened, SecureDossier allows people to perform a scan and to check for problems with the computer. It is likely that 'issues' will be detected (see our example in the screenshot above).
Note that programs or applications that are promoted using the "bundling" method should not be trusted. Typically, they display scan results that include a number of so-called issues, however, the results are fake. In many cases, these programs display numerous problems simply to encourage people to purchase the software (pay for activation).
The free version allows them to perform a free scan, however, to fix detected issues, they are required to purchase the full software. It is not certain that SecureDossier is one of these rogue apps, however, most PUAs operate in this way, and thus cannot be trusted.
Furthermore, "bundled" apps often come in packs: users are tricked into installing more than one PUA at once. Typically, PUAs are delivered together with other unwanted apps such as browser hijackers, adware-type apps, and so on. Applications of this type usually display intrusive advertisements such as coupons, banners, surveys, pop-ups, etc.
They also gather information relating to users' browsing habits such as entered search queries, IP addresses, geo-locations, URLs of visited websites (addresses), and other similar details. Developers share the data with third parties (cyber criminals) who misuse private data to generate revenue.
We recommend that you uninstall SecureDossier and other installed PUAs and avoid installing apps of this type in the future.

SecureDossier is just one of many apps categorized as a PUA. Other examples are One Click Booster, Registry Scanner, and Lowe Registry Cleaner. Most of these apps are presented as useful and legitimate, however, these are attempts to trick people into using them. Additionally, when installed, PUAs deliver none of the features or tools promised.
How did potentially unwanted applications install on my computer?
Some unwanted apps can be downloaded from websites that developers use to promote them, however, in most cases, people install PUAs through intrusive advertisements that they click, or when software developers use a deceptive marketing method called "bundling".
They hide information about unwanted apps in settings such as "Custom", "Advanced" and other pars of software download/installation set-ups. Note, however, that these unwanted installations and downloads mostly occur when people do not check available download/installation settings/options and leave them unchanged.
How to avoid installation of potentially unwanted applications?
To prevent unwanted installation/download of potentially unwanted applications, download/install software and browse the web carefully. Download software (especially if it is free) using official/trustworthy sources and direct links. Avoid using third party software downloaders, Peer-to-Peer networks such as torrents, eMule and other similar channels.
Do not skip installation/download steps. Check "Custom", "Advanced" and other similar settings/options first. Decline offers to install or download unwanted software. Do not trust intrusive ads, since they often open dubious (potentially, malicious websites) such as gambling, adult dating, pornography, and so on.
If you encounter intrusive ads or redirects to dubious websites, check for unwanted extensions, plug-ins, and add-ons installed on your browser.
Remove unwanted/suspicious entries immediately. You are also advised to apply this to programs installed on the operating system. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
