The clamscan.exe is an executable file from SourceFire, Inc. that belongs to the product ClamWin Antivirus, which is a non-system, cross-platform software capable of detecting multiple types of malicious software, including viruses. This file is one of four parts of the Antivirus software, and it functions as a secondary scanning engine. However, it does not connect to the main scanning engine, so virus definition files are always loaded unto the main program.

These may result in increased CPU usage, abnormal Windows System Registry performance, computer crashes or freezes, system slowdowns or BSoD (Blue Screen of Death).
