This confirms that the producer has been registered with a certificate authority. It is unusual for the service not to provide any indication of how and why it is required. The file does not come from Microsoft and is not part of the operating system. It contains a digital signature from Verisign, a subsidiary of Symantec. Verisign thereby confirms this file's authenticity and integrity. SymIM.sys 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, 0% of all experts consider this file to be a possible threat. The probability that it can cause harm is high.
If you see this file on your hard drive or in Windows Task Manager, please make sure that it is not a malicious variant.
