Hello Nancy,
Antivirus and Antimalware programs will sometimes flag the other as potentially unwanted software (PUPS).
You can add an exclusion by doing the following in malware bytes.
Should users wish to keep this program and exclude it from being detected in future scans, they can add the program to the exclusions list. Here’s how to do it.
Open Malwarebytes for Windows.
Click the Detection History
Click the Allow List
To add an item to the Allow List, click Add.
Select the exclusion type Allow a file or folder and use the Select a folder button to select the main folder for the software that you wish to keep.
Repeat this for any secondary files or folder(s) that belong to the software.
If you want to allow the program to connect to the Internet, for example to fetch updates, also add an exclusion of the type Allow an application to connect to the internet and use the Browse button to select the file you wish to grant access.
Additionally you do not need to be running two Antivirus programs at the same time, I recommend uninstalling Bitdefender.
