Google Chrome has fixed a bug that enabled antivirus programs on Windows 10 to lock newly created files. The bug meant Windows 10 users would experience issues trying to save bookmarks, for example, due to the web browser having difficulty creating the corresponding file. The fix attempts file creation multiple times to overcome the possible race condition in which an antivirus program takes control of (and locks) a file being simultaneously accessed by Chrome. It is expected the next version of Google Chrome will come shipped with it.
