Hello, my name is Dimitris and I have pc with windows 11 and bitdefender total security installed and fully updated. Since yesterday when I open mozilla firefox a file on desktop appears with the name bd_config.cfg. I wonder whether my pc is infected with a virus or malware?

Best Regards

From this comment: https://www.reddit.com/r/BitDefender/comments/1ovarkl/comment/noq97f5/

"Had this issue as well after Firefox updated today. I have found a solution but I am not sure if it just masks the problem or this was always the case.

I noticed that the Firefox shortcut on the desktop changed into an executable so when I ran the app from the windows start menu which runs the "C:\Program Files\Mozilla Firefox\firefox.exe" by default, the cfg file does not appear on the desktop. It does appear in the firefox folder.

I deleted the desktop executable and replaced it with the shortcut so it no longer causes the cfg file to appear on the desktop."

Does this help?
