What kind of program is PDFsharp?
PDFsharp seems to be a tool designed for handling PDF files. Yet, upon thorough examination, it emerges as an unreliable application with an unclear purpose. Additionally, it comes bundled with other dubious apps - it gets installed together with other suspicious elements. Consequently, it is strongly advised not to place trust in PDFsharp.
PDFsharp in detail
Typically, apps created for processing PDF files include functionalities allowing users to perform tasks like viewing, editing, or converting PDF documents. Many legitimate PDF tools in the market serve these purposes and more. However, the lack of clarity regarding PDFsharp's purpose raises concerns about its legitimacy and reliability.
Applications with unclear or undisclosed purposes may potentially be associated with malicious activities, ranging from adware and unwanted browser modifications to more serious security threats. As mentioned in the introduction, PDF is packaged with other suspicious elements.
The specific apps bundled with PDFsharp can vary, but the common thread among them is their association with potentially unwanted or suspicious software. In many cases, such bundled apps might include adware, which aggressively displays intrusive advertisements to users, disrupting their browsing experience and potentially compromising their privacy.
Another category of bundled apps could be browser extensions or toolbars that modify users' browser settings without their explicit consent. These modifications might result in changes to the default search engine, homepage, or new tab pages, leading to a less desirable browsing experience. Some of these extensions may even collect and transmit user data, posing privacy concerns.
Given the uncertainty surrounding the specific bundled apps with PDFsharp, users are strongly advised to exercise caution and avoid installing such software.

How did unwanted software install on my computer?
Users may inadvertently install applications like PDFsharp through various deceptive methods employed by their developers. One common tactic involves software bundling, where users download seemingly legitimate programs, and the installation process includes the simultaneous installation of additional unwanted applications, often without clear user consent.
Furthermore, users may fall victim to deceptive online practices, such as misleading advertisements, fake download buttons, or phishing emails. Downloading from P2P networks, unofficial app stores, third-party downloaders, and similar sources can also lead to unwanted installations.
How to avoid installation of unwanted applications?
Prioritize downloading software only from reputable sources such as official websites or authorized app stores. When installing applications, carefully read through each installation prompt, paying close attention to any pre-selected options or checkboxes that may indicate the inclusion of additional software.
Exercise caution while browsing the internet. Be wary of clicking on misleading advertisements, especially those promising free software downloads or claiming system issues that require immediate attention. Avoid downloading software from unfamiliar or suspicious websites, regularly update the operating system and apps, and use reputable security.
If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
