The AcroIEHelperShim.dll file is an essential component of the Adobe Acrobat software suite, particularly its function within web browsers. This Dynamic Link Library (DLL) file is responsible for helping display Adobe PDF documents directly within Internet Explorer. The technology behind this functionality is the Browser Helper Object (BHO), a plugin that integrates seamlessly with your web browser, allowing you to view PDF files without having to open them in a separate program like Adobe Acrobat Reader.
Is AcroIEHelperShim.dll Safe to Run?
The good news for users is that AcroIEHelperShim.dll is a legitimate file from Adobe Systems and is safe to run. It carries a digital signature from Verisign, a trusted certification authority, which confirms its authenticity and integrity. However, it is essential to ensure the DLL file in question is located in the appropriate folder, such as C:\Program Files\Common Files\Adobe\Acrobat\ActiveX\. A file with the same name located elsewhere, specifically in system folders like C:\Windows or C:\Windows\System32, could potentially be a disguise for harmful software.
Could It Be a Virus or Malware?
While AcroIEHelperShim.dll itself is not a virus or malware, it’s always prudent to remain vigilant. Cybercriminals are known to create malware that mimics legitimate files. Always ensure your antivirus software is up to date and perform regular system scans. If your security software flags this DLL as suspicious, it could be a false positive, or it could indicate that the file has been compromised or is a malware-impostor.
Common Issues with AcroIEHelperShim.dll
Some users may experience issues with AcroIEHelperShim.dll, such as browser crashes or error messages. Frequently, these problems can be resolved through simple troubleshooting steps. For example, if you find that PDFs no longer display within Internet Explorer, or you receive errors related to the DLL, it may be because the plugin has been disabled. Re-enabling the Adobe PDF Link Helper in Internet Explorer’s Manage Add-ons section often fixes the problem.
