@miguelm Before I go to answer, I want to say it’s important to provide information requested. Like you chose not to advise which OS and version of Brave you’re using. This can be important in people checking things out. Another thing to ask would be if you downloaded Brave from or if you got it from somewhere else?

Another thing that can be important is to know which antivirus you’re using. For example, are you using eset security?

The main thing I’d do is make sure to do a deep scan on your device. You may need to try another program, such as Malwarebytes to see if it might find something. Or you can even use Windows Defender as a secondary.

if you download it from the official page of brave

@miguelm ok, so you do use eset internet security. Please see the link I provided earlier that goes to their site. You may want to submit to them as well. From what they are sharing, it seems to be a false detection type of thing through them.

I’ll tag @Mattches here as well in case he has anything to add to this. But I think overall you need to speak to support from your antivirus program.

@Saoiray is correct here — as long as you downloaded the install file from the official download page, there is nothing malicious contained within and you’ll need to add an exception for it in your AV and also maybe reach out to the vendor and let them know that it is reporting a false positive for Brave (I will also submit this report on my end).

The problem was that I installed an extension that was damaged, deleted it and now I don’t get the same problem again
