PUA / PUP is the acronym for “Potentially Unwanted Application”. A potentially unwanted application (PUA) or potentially unwanted program (PUP) is software that usually comes bundled with freeware software and will display pop-ups or install a toolbar in the default browser.
Some of them will change the homepage or the search engine, others will run several processes in the background, slowing down the PC or will display numerous ads. These programs can be installed without your consent (also called adware) or will be included by default in the express installation kit (ad-supported).
In order to avoid installing such PUA / PUP, you have to always install the main software by choosing the advanced/custom options.
Also, some of these programs are legitimate, but their actions on the system should be stopped if they are performed without the user’s explicit consent. For instance, commercial keyloggers are legitimate applications installed by the employer to monitor the activity on the employees’ workstations.
In such a case, an exclusion has to be made and Bitdefender will automatically skip these files/folders.
If you are not sure whether or not the software is legitimate, you can submit a scan log.
The detection will be analyzed by our Virus Analysts to determine if it is a low-risk application or specific actions need to be taken in order to remove the threat from your PC.
