Hello @cezarF,

Which pop-up? What does it say?

That's what I suspected, that the app redirects to suspicious URLs. And if it attempts to connect to those websites continuously, then yes, Bitdefender will display relevant warnings, and because these are security-related events, the notifications in this case cannot be disabled. You could try to add an exception for the Kodi app, but this doesn't guarantee that the pop-ups are suppressed..

Precisely because Bitdefender detects something there, I advised against accessing those websites knowingly, but since the actual app opens and redirects to those pages, then perhaps it's a good idea to reconsider the level of security and trustworthiness that the app provides. But even legitimate, well-intentioned apps sometimes trigger suspicious-looking website connections or redirections for various reasons, many of which are related to built-in advertising or tracking features.

Many apps (mostly free but also paid) rely on advertising or affiliate marketing links. These ads are often served via third-party ad networks, which dynamically load content from multiple servers. Even if the app developer is reputable, the ad network might inadvertently serve a malicious or suspicious link—sometimes due to a compromised ad network or an unscrupulous advertiser. Occasionally, the antivirus software flags specific tracking endpoints as dangerous if they have been compromised in the past or use obfuscated code patterns that resemble malware.

Also, there could be genuine threats hiding in these redirect scenarios, as some compromised pages may attempt “drive-by downloads” using browser exploits, automatically installing malware without explicit user permission or awareness. Moreover, certain malicious pages attempt to deliver ransomware payloads.
Once installed, ransomware can lock access to files or systems until a ransom is paid.

If the app you are using is considered trustworthy, then perhaps you can report the detections to Bitdefender Labs, so the security researchers can investigate those redirects and the overall app behavior, to establish if there is indeed a threat there, of if it's a PUP/PUA, or something else. You can use the form available at the link below to submit a sample of the detected URLs, or the actual app that you are using:

If the detection is legitimate, it will be kept. If these are false alarms, they will be corrected in due time and this means you will also get rid of those pop-ups.

Let us know how it goes.

Regards

Obviously, the concept behind the notification is to alert you whenever there's a possible threat, so this is the opposite of "undermining" security, imho. Myself, I totally understand that such notifications can sometimes be inconvenient, but I think attempting to stop them by adding exceptions wouldn't be the best solution.
It's like hiding the dirt under the rug instead of cleaning it up.. 🙄
But each with its own, I personally don't go on websites that push loads of ads and other nagging content, because apart from the annoyance of banners and notifications popping up everywhere, there's a good chance of malicious activity as well..
