What you should know about MSASN1.dll ASN.1 Runtime APIs

MSASN1.dll is not part of Windows, but it is important nonetheless. The file MSASN1.dll is found in a subdirectory of C:\Windows. The file size is 34,304 bytes.
This so-called dynamic link library (DLL) contains all the functions that have been transferred to a separate file. These transferred functions are available not only to this particular program, but can also be used by other applications. For this service - unlike Windows' own system services - there is no good description available. The file also can also affect other applications by changing their properties. Such manipulation can cause an application to do things other than what it is intended to do. The file was developed by a so-called third party provider - and not by Microsoft. This process does not appear as a visible window, but only in Task Manager. The file contains Microsoft's digital signature. This confirms its authenticity. MSASN1.dll appears to be a file that was compressed by an EXE-Packer. This technique is often used by trojans to keep the file size small and also hamper debugging efforts. However, this in itself is not sufficient reason to presume malicious intent, since even well-intentioned, professional software producers take advantage of compressed files. For this reason, 40% of all experts consider this file to be a possible threat. The probability that it can cause harm is high.

A MSASN1.dll file has a 38% certainty of being dangerous if it is found in the C:\Windows\System32 directory.

This MSASN1 program does not have a visible window, and does not appear on the taskbar. The service has no characteristics or description of its own. This is unusual. MSASN1.dll also can also affect other applications by changing their properties. Such manipulation can cause an application to do things other than what it is intended to do.

To remove ASN.1 Runtime APIs from your computer, please follow the manual instructions below or use an automatic uninstaller product.

How to tell if MSASN1.dll (ASN.1 Runtime APIs) was uninstalled cleanly

After uninstalling, restart your computer. Then start Windows Explorer and see if there is still a folder with the name of the software under C:\Program Files. Be sure to check the Registry as well for remnants of ASN.1 Runtime APIs. To do this, start "Regedit", then look under "HKEY_LOCAL_MACHINE" > "Software" for ASN.1 Runtime APIs or the name of the producer. Always keep in mind that only a computer professional should ever directly delete entries in the Windows Registry.

What to do if a program does not uninstall

The easiest way to remove any kind of software cleanly and accurately is to use an uninstaller tool. Because the uninstaller automatically creates a backup, there is no risk of anything going wrong.

If Windows not working quite right for you, or if startup is taking a long time, or MSASN1.dll is causing problems for you, a good Windows diagnostic tool may very well help. This is especially effective when it comes to older computers that have accumulated vast quantities of "garbage data" as the result of many software installs and uninstalls.
