A file or other data unit may be scanned for malicious code by calculating a hash value of a portion of the file or data unit and transmitting the hash value of the portion over a computer network to a remotely located server computer. In the server computer, the hash value of the portion may be compared to hash values of malicious codes. The server computer may send the result of the comparison over the computer network to the client computer. The client computer may send one or more additional hash values of other portions of the file or data unit when the result indicates that the hash value of the portion matches a hash value of malicious code. Otherwise, the client computer may deem the file or data unit to be free of malicious code.
