The 'AppMaster' software is not likely to appear on your screen if you are not searching for it specifically. The AppMaster program is shown to users as a product called 'PDF PRO 100' that you can find at h[tt]p://www.pdfpro100[.]com/fast_download/. PC users who may want to convert DOC, PDF, XLS, JPG, and HTML files to PDF format may be interested in using the free 'PDF PRO 100' software from Tersertude Ltd. You should note that 'PDF PRO 100' and 'AppMaster' are identical programs, which are installed to the default path C:\Users\user account\AppData\Roaming\AppMaster\ and may drop resources to C:\Users\user account\AppData\Local\Temp\IXP000.TMP\.
The main process is called 'AppMaster.exe' (SHA-1:b0d26c5cf4221e7801fd4f3d7543f2ea8cc578a0), which displays a blue triangle icon in your taskbar. However, the program window shown to the users features the name 'PDF Convertor' and a drop box that says 'CHOOSE A FILE OR DRAG HERE.' You should be aware of read the Terms of Use and Privacy Policy posted at h[tt]p://www.pdfpro100[.]com/eula.html and http://www.pdfpro100[.]com/privacy.html. 'PDF PRO 100' is presented as an independent document conversion service. Also, the installer for 'PDF PRO 100' includes a marked option that says 'I agree to set my search settings to Bonefreeze.' This means that installing 'PDF PRO 100'/'AppMaster' would change your Internet search settings to Bonefreeze.com. The Search by Bonefreeze is subject to other EULA and Privacy Policy that you can find at h[tt]p://www.bonefreeze[.]com/privacy.
We had the opportunity to scroll through the license agreement for 'AppMaster' and noticed that the program comes with what is described as a "complementary software." The said "complementary software" is installed automatically. Once, you install 'AppMaster'/'PDF PRO 100' by Tersertude Ltd. you grant it the privilege to install more software on your system automatically. The Terms of Use include a clause that says the 'PDF PRO 100' software can push targeted advertisements to your screen and an identifier is dropped to your machine. Some cybersecurity vendors flag 'AppMaster' as adware due to its shady TOS and ability to install applications automatically.
We discovered that the 'PDF PRO 100' window produced by 'AppMaster.exe' functions as a Web application. The 'PDF PRO 100' Web application is freely accessible at h[tt]p://baseapp.pdfpro100[.]com via any standard Web browser. You may be interested to know that 'PDF PRO 100' does not convert files. Instead, the documents dropped in the application are sent to a server called 'alina.infra.cloudconvert[.]com,' which is operated by Lunaweb Ltd. and hosts their document conversion service called Cloudconvert.com. In addition, the official Cloudconvert.com service has a Google Chrome extension that you can install for free from Chrome.google.com/webstore/detail/cloudconvert/hfpmbfgodkfcebpgheiedaddoikmljkk. The CloudConvert extension from h[tt]ps://cloudconvert[.]com does not show advertisements like 'PDF PRO 100' by Tersertude Ltd. The company that released 'PDF PRO 100'/'AppMaster' does not mention a partnership with Cloudconvert.com and we suspect that there may be foul play involved.
