The m3spdxcd.dll file belongs to an unknown process. While unknown files are not unusual, you should generally run your antivirus software when you run across one. You should also use an anti-spyware program like SpyZooka to check for malicious non-virus programs like Trojans and adware. If your system is free of viruses and other malicious programs but you are still getting an error with this file, you may be able to solve this issue by cleaning your registry.
Dll files contain bits of code that programs can run whenever needed and can be shared between multiple programs. Windows keeps track of these files using the registry. If there is a mistake in the registry, Windows cannot find the dll files, and any programs that need to use them will not run. ZookaWare PC Cleaner cleans up errors in the registry, to get your system back to normal. ZookaWare PC Cleaner is guaranteed to find and fix every mistake in the registry. A free ZookaWare PC Cleaner scan will tell you how many errors are in your registry.
