Have you ever opened your Windows Task Manager to clean up extra or unused processes and applications on your PC? If you have, then you are probably familiar with the item under the Processes tab named \”twain dll\”.

But just what exactly is that process? What is it doing on your computer? Is it harmful? Would deleting that specific process lead to difficulties or errors in your computer? If you have ever encountered errors concerning this certain file, then be sure to read the information below. You will learn all about this dynamic link library file, and how you can safely fix any error associated to it.

What is it?

This dll file is a module that works with still images. It is usually listed in the computer registry as a file added by the \”Twain Source Manager\”, with its creator being dubbed as \”Unknown\”.

It contains an application processing interface, and is deemed to be relatively harmless to computers. This file is classified as a non-system process. Non-system processes usually come from previously installed programs downloaded from the Internet or memory devices. While most non-system processes are harmless, there have been reports about the twain.dll virus spreading in different computers.

The so-called virus that comes with the file is also called the twain.dll thunking server virus. Users who have experienced this virus report that their computers did not perform as efficiently as before, and that there was a noticeable lag in the opening and closing of several programs. Upon checking the Windows Task Manager, one of the users found that the Processes tab contained two items described as the twain.dll 32-bit thunking server. When the said user restarted his processes, the virus simply bounced back and made the computer slow and inefficient.

If you have encountered the same problems as described above, or you simply want to play safe and delete the twain.dll file from your computer, read the following options given below.

Option 1: Close all running programs immediately.

This is especially important to users who have been notified by their computer that a virus or malware under the Twain DLL category has entered the system. Be sure to save your work or important documents in a backup driver to prevent total data corruption and loss.

Option 2: Run a complete anti-virus scan of your computer\’s memory.

If you do not have a reliable antivirus program installed, you will have problems detecting and deleting incoming viruses and malware. Be sure that your computer is protected from virtual threats by equipping it with a strong and reputable anti-virus program.

If your antivirus program reports that a virus linked to the file is found, do what you can to isolate the file or repair it immediately.

Option 3: Use a Windows Disk Defragmenter.

Another way of optimizing your computer\’s speed or relieving it of dynamic link library file errors is to clean the hard drives with a disk defragmenter. You can purchase or download disk defragmenters and set the parameters for them to target unused data. The program will then ease the load of your disk fragmentation and allow your computer to speed up its processes, including DLL file recognition and location.

Option 4: Update your drivers and hardware.

It is important that you keep both your software and hardware components updated with the latest patches or content. One of the common reasons why users encounter DLL file errors is because they have failed to update their drivers and hardware.

Make a point of keeping your computer updated with the latest developments by ensuring that you install updates and patches required for the smooth functioning of hardware and drivers. This is applicable to users who receive notifications about missing dynamic link library files whenever they try to install new printers or external hard drives.

Option 5: Learn how to use troubleshooting effectively.

If you suspect that your DLL file problems are more deep-rooted than hardware updates, then use the troubleshooting option on your computer. You should be notified if your system detects any hardware or software problems related to missing files. In the event that your computer cannot pinpoint the source of the problem, consider having your computer checked at a local or professional computer repair shop.
