What is PDFConverter?
PDFConverter is a piece of software endorsed as a tool for converting various file formats. According to its promotional material, it is capable of converting Doc, PDF, XLS, JPG, HTML, and many other formats.
Since most users download/install PDFConverter inadvertently, it is classified as a PUA (Potentially Unwanted Application). Additionally, it is likely that if this app is present on the system - other PUAs have also infiltrated it.
PDFConverter has been observed being distributed alongside adware and browser hijackers. Unwanted apps may have unmentioned, heinous functionalities. PUAs are designed to cause redirects, run intrusive advertisement campaigns, modify browsers, and collect browsing-related data.
While dubious distribution techniques may be used to promote legitimate products, they are more commonly employed to proliferate untrustworthy software. PUAs usually appear legitimate and offer a variety of "useful" and "advantageous" features.
However, despite how good they may sound - they are seldom operational. Fake anti-virus tools are prime examples of this; they require activation (i.e., purchase) to perform the advertised functions, yet following activation - they are nonoperational.
PUAs may have harmful functionalities, and these functions can be in different combinations. Some of these applications can force-open sale-based, misleading, untrustworthy, compromised, deceptive/scam, and malicious websites. Adware-types deliver intrusive advert campaigns.
The delivered ads diminish the browsing experience and pose a threat to device/user safety. Once clicked on, intrusive advertisements redirect to unreliable/malicious sites and may be able to stealthily download/install software.
Another type of PUA called browser hijacker operates by modifying browser settings and restricting/denying access to them - in order to promote fake search engines. The promoted web searchers rarely can provide search results, so they redirect to Google, Bing, Yahoo, and other genuine ones.
Furthermore, most PUAs have data tracking abilities. Targeted information includes (but is not limited to): URLs visited, pages viewed, search queries typed, IP (Internet Protocol) addresses, geolocations, and personally identifiable details.
The collected data is then monetized by being shared with and/or sold to third-parties (potentially, cyber criminals). In summary, presence of unwanted apps on devices - can result in system infections, severe privacy issues, financial losses, and even identity theft.
To protect device integrity and user privacy, all suspicious applications and browser extensions/plug-ins must be removed immediately upon detection.

SpeedFixTool, DriverScape, One Click Privacy, TakeMyFile, and ZipConvertAce are some examples of other PUAs. They appear legitimate and innocuous. Users are enticed into download/installation and/or purchase with offers of a broad range of functionalities.
However, the promised features usually do not work. Functionality and user safety are irrelevant, as the only goal of unwanted software is to generate revenue for the developers.
Therefore, instead of delivering on any promises, PUAs can cause redirects, run intrusive advertisement campaigns, hijack browsers, and gather sensitive and private data.
How did potentially unwanted applications install on my computer?
Select PUAs (e.g., PDFConverter) have "official" promotional/download webpages. These applications are also distributed via download/installation setups of other programs. This deceptive marketing technique of packing regular software with unwanted or malicious additions - is called "bundling".
Rushed download/installation processes (e.g., ignored terms, skipped steps and sections, used "Easy/Express" settings, etc.) increase the risk of unintentionally allowing bundled content.
Intrusive advertisements proliferate PUAs as well. Upon being clicked, the ads can execute scripts to make download/installations without user permission.
How to avoid installation of potentially unwanted applications?
It is recommended to research software before download/installation and/or purchase. Additionally, all downloads must be done from official and verified sources.
Untrustworthy download channels, e.g., unofficial and free file-hosting websites, Peer-to-Peer sharing networks, and other third-party downloaders - commonly offer dangerous and/or bundled content.
When downloading/installing, it is recommended to read terms, explore possible options, use the "Custom/Advanced" settings and opt-out from additional apps, tools, functions, etc.
Intrusive adverts appear ordinary and harmless; however, they redirect to highly questionable sites (e.g., gambling, pornography, adult-dating, and so on).
In case of encounters with ads and/or redirects of this type, the system must be inspected and all suspect applications and browser extensions/plug-ins detected - immediately removed from it.
If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
