How to remove ChangeToPDF from Mac?

What is ChangeToPDF?

The ChangeToPDF app is promoted as a PDF converter that allows users to convert their PDF files to various other formats such as Word, PowerPoint, Excel, PNG, JPG, etc. In fact, this software originates from the Bundlore adware family and is used to distribute adware-type applications to Mac computers via the "bundling" method. If installed, adware displays intrusive advertisements and gathers information.

ChangeToPDF adware

If ChangeToPDF is installed on a Mac computer, it is likely that other adware-type apps are also installed - its installer is used to distribute additional, potentially unwanted applications (PUAs). When installed, adware begins to deploy coupons, banners, surveys, pop-ups, and other similar advertisements. As well as being annoying, if clicked, these ads can open dubious websites and execute scripts that download and install other PUAs. Another problem with adware is that the apps often work as data tracking tools. They collect information relating to users' browsing habits such as geolocations, IP addresses, entered search queries, URLs of visited pages, and so on. They sometimes also record sensitive, personal data. People who develop these apps usually share the information with third parties (potentially, cyber criminals) who misuse it to generate revenue. For these reasons, we recommend that you uninstall all adware-type apps and other PUAs immediately.

Adware-type applications are all very similar. Their main purposes are to serve users with ads and collect various user-system information. Adware developers promote these apps as 'useful' tools that supposedly provide various features. Unfortunately, once installed, they deliver no real value. Only the developers benefit from this rogue software. Some examples of other adware-type apps are PDF Mac Master, Snap Media Player, and RadioSpot.

How did adware install on my computer?

Adware-type apps are often bundled with download or installation set-ups of other software that people download intentionally. Developers include potentially unwanted apps into the set-ups but do not properly disclose this information - they hide them in "Custom", "Advanced" and other sections, and hope that people will not check them. Unfortunately, many people rush and allow PUAs to be downloaded and installed. Adware and PUAs are also downloaded and installed when clicking intrusive advertisements.

How to avoid installation of potentially unwanted applications?

Do not use third party software downloaders/installers or other similar sources to download software. Download from official, trustworthy websites and use direct links only. Do not skip download or installation setup steps and check "Custom", "Advanced" and other settings. Dismiss any offers to download or install unwanted apps and only then finish the process. Be careful with intrusive ads, especially on suspicious, dubious websites - if clicked, they can redirect to other untrustworthy websites (gambling, pornography, adult dating, and so on). If you encounter these redirects or ads, check the list of installed extensions, plug-ins, and add-ons on your browser and programs on your computer. Uninstall all unknown or unwanted applications/programs immediately. If your computer is already infected with ChangeToPDF, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
