What is PDF Mighty?
PDF Mighty is a piece of rogue software, endorsed as a tool capable of converting files (e.g. Microsoft Office documents) into the PDF format. However, due to the dubious methods used to distribute this application, it is classified as a PUA (Potentially Unwanted Application). One of the primary purposes of PDF Mighty is to promote the SearchMighty browser hijacker. Furthermore, PUAs often have unmentioned heinous abilities and the advertised features - are rarely operational.
PUAs typically appear legitimate and offer a broad range of "useful" and "advantageous" functionalities. However, these functions seldom work as advertised and in most cases - they do not work at all. Some PUAs (e.g. fake anti-viruses) require activation (i.e. purchase) to perform the promised features, yet following activation - they remain nonoperational. PDF Mighty promotes another PUA - SearchMighty. This piece of software is categorized as a browser hijacker. It operates by assigning the addresses of fake search engines as browsers' homepage, new browser tab/window and default search engine URLs. Hence, with a browser hijacker installed: every new browser tab/window opened and search query typed into the URL bar - redirect to the promoted address. Illegitimate search engines usually cannot provide search results, so they redirect to (or cause redirection chains ending with) Google, Yahoo, Bing and other genuine ones. Browser hijackers can also restrict/deny access to the browsers' settings and/or undo any permitted changes made. PUAs can have varied heinous abilities and they can be in different combinations. Unwanted apps can force-open unreliable and dangerous webpages. Adware-types deliver intrusive advertisement campaigns, i.e. enable the placement of pop-ups, banners, surveys, etc. - on any visited website. These ads are more than just a nuisance, they are considered to be harmful as well. Once clicked on, intrusive adverts redirect to untrustworthy/malicious sites and some can even stealthily download/install software. What is more, most PUAs (browser hijackers included) can track data. They can monitor browsing activity (visited URLs, viewed pages, searched queries, etc.) and collect personal information extracted from it (IP addresses, geolocations and other details). This sensitive information is then monetized by being shared with and/or sold to third parties (potentially, cyber criminals). In summary, presence of unwanted applications on devices can lead to system infections, severe privacy issues, financial losses and even identity theft. To ensure device integrity and user safety, all suspicious apps and browser extensions/plug-ins must be eliminated immediately upon detection.

PC Gold Optimizer and system repair, ID SafeXpress, Registry Cleaner, DiskFixer - are some examples of other potentially unwanted applications, LiveSportSearch, ConverterSearchTool, MagicMovieSearch - and of browser hijackers. As mentioned in the introduction, unwanted software appears ordinary and harmless. However, the only goal of PUAs is to generate revenue for the developers; hence, functionality and user safety are irrelevant. Instead of delivering on any promises, these apps can cause redirects, modify browsers, run intrusive ad campaigns, collect vulnerable and personally identifiable information.
How did potentially unwanted applications install on my computer?
Select PUAs (e.g. PDF Mighty) have "official" promotional webpages from which they can be downloaded. They can also be downloaded/installed together with other software. This deceptive marketing tactic of packing regular products with unwanted or malicious additions - is termed "bundling". By rushing through download/installation processes (e.g. by ignoring terms, skipping steps and sections, using "Easy/Express" settings, etc.) - users risk inadvertently allowing bundled content into their devices. Intrusive advertisements proliferate PUAs as well. When clicked on, the ads can execute scripts to download/install these applications without user permission.
How to avoid installation of potentially unwanted applications?
It is recommended to always research software products prior to download/installation and/or purchase. All downloads must be done from official and verified sources. Since untrustworthy download channels, like: unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders - often offer harmful and/or bundled content. Download and installation processes must be treated with caution; that includes - reading terms, studying all available options, using the "Custom/Advanced" settings and opting-out from additional apps, tools, functions, etc. Intrusive adverts appear legitimate, however they redirect to highly questionable sites (e.g. adult-dating, pornography, gambling, and so on). Should users experience such ads and/or redirects, they must inspect their devices and immediately remove all suspect applications and browser extensions/plug-ins. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
