I.e., most users are tricked into installing this app, and it is often distributed together with other software. This deceptive marketing method of pre-packing regular content with PUAs is called "bundling".

What is dl-youtube-mp3[.]net?

The dl-youtube-mp3[.]net website is presented as a free, fast, and easy-to-use converter that allows download and and conversion of YouTube video files to MP3 and MP4 formats. As with most websites of this type, however, it uses rogue advertising networks.

Therefore, people who use dl-youtube-mp3[.]net are forced to visit various untrustworthy websites. Another reason to avoid this site is that it is illegal to download videos from YouTube.

What is Hlpradc?

Hlpradc is an unwanted application that is installed through another app of this kind called Mac Ads Cleaner. Hlpradc is the reason why MacOS Catalina users regularly see a pop-up window stating that "hlpradc" will damage their computers and they should move it to the Bin.

Furthermore, this pop-up often freezes operating systems. To stop this pop-up from appearing, it is necessary to remove Hlpradc and all associated files. Mac Ads Cleaner should also be removed.

What is TabApp?

TabApp is the name of an adware-type app, which belongs to the Pirrit adware family. Software of this type is usually designed to serve advertisements, however, it is sometimes used to collect information relating to users.
