Passport.dll file information

The Passport.dll process does not give any clues as to the producer or the name of the associated software; instead, only the following file properties can be determined.

Description: Passport.dll is not essential for the Windows OS and causes relatively few problems. Passport.dll is located in a not unambiguous folder. The file size on Windows 10/8/7/XP is 0 bytes. 
This .dll file is a Browser Helper Object (BHO) that runs automatically every time you start your web browser. BHOs are not stopped by personal firewalls, because they are identified by the firewall as part of the browser itself. BHOs are often used by adware and spyware. IDs used by this BHO include 4D594333-0076-A76A-76A7-7A786E7484D7 or 57334934-2D47-006A-76A7-7A786E7484D7 or 83 more variants. The Passport.dll file is a file with no information about its developer. Note: File does not exist any longer. The program is not visible. It is able to change the behavior of, or monitor Internet Explorer. The file is not a Windows core file. Therefore the technical security rating is 61% dangerous, however you should also read the user reviews.

Best practices for resolving Passport issues

The following programs have also been shown useful for a deeper analysis: Security Task Manager examines the active Passport process on your computer and clearly tells you what it is doing. Malwarebytes' well-known anti-malware tool tells you if the Passport.dll on your computer displays annoying ads, slowing it down. This type of unwanted adware program is not considered by some antivirus software to be a virus and is therefore not marked for cleanup.

A clean and tidy computer is the key requirement for avoiding PC trouble. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
