Hello,

Since the beginning of December, it began to happen that the opera was randomly opening second window. The window opens with an empty page, followed by a tab with the address: //adform.com, after a while the tab https://artsai.com/privacy/ and after another while the tab: //oracle.com/ ... Opera is My main browser. I have it updated, I have an active antivirus program and the computer scan found no malware, I downloaded Malwarebytes for sure that it also found nothing. I tried to add an extension of Block Site to the Opera and all that happened is that now there are pages that appear as blocked but windows still appear...

Thank you for any help

@leocg Yes Opera is my default browser. Sometimes I use Chrome but really not often. I'm not sure why any other program should turn the same pages at the same time and then close it after a while

@leocg I have Opera One (version: 117.0.5408.32) and I did a computer test several times through antivirus and I downloaded malwarebytes and all these tests went well. I also noticed that this site appears every day at about the same time around 20:15 and 20:17. I deleted all the extensions up to 3. AdBlock Plus, Avast and Block Site (With Block Site I tried to block those three pages that open to me automatically).
