lzo2.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like lzo2.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like MpSigStub.exe - to follow. These files were created so that multiple programs (eg. Steganos Online Shield VPN) could share the same lzo2.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.
Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when lzo2.dll is attempted to be loaded either when Steganos Online Shield VPN is starting up, or in some cases already running. Some of the most common lzo2.dll errors include:
- Access Violation at address - lzo2.dll.
- lzo2.dll could not be found.
- Cannot find C:\Program Files (x86)\Steganos Online Shield\openvpn64\lzo2.dll.
- Cannot register lzo2.dll.
- Cannot start Steganos Online Shield VPN. A required component is missing: lzo2.dll. Please install Steganos Online Shield VPN again.
- Failed to load lzo2.dll.
- The application has failed to start because lzo2.dll was not found.
- The file lzo2.dll is missing or corrupt.
- This application failed to start because lzo2.dll was not found. Re-installing the application may fix this problem.
Your lzo2.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Steganos Online Shield VPN), or deleted by a malware infection. Furthermore, lzo2.dll file corruption could be caused from a power outage when loading Steganos Online Shield VPN, system crash while loading lzo2.dll, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.
