Upon detection of a suspicious file, a client computer sends feedback data to an anti-malware service over the Internet. Files that are not suspicious or that are known clean are not reported; files that are known malware are acted upon immediately without needing to report them to the anti-malware service. Upon detection, no alert or warning is provided to the user of the client computer. The anti-malware service correlates data from other detection engines on the client computer or from other client computers and determines whether the file is malware or not. A new virus pattern is generated if the file is malware and includes the virus signature of the file; the new virus pattern is distributed back to the client computers. If not malware, no action need be taken, or, the virus signature of the file is removed from existing pattern files.

The use of a marker in a file to assist in the signing and / or verification of the file. The marker is recognized by the signing authority. The marker has a certain execution transparent context that reduces or eliminates the impact of the marker on execution. A signing authority accesses the file, finds the marker within the file, and identifies the execution transparent context system. The signing authority then uses the execution transparent context system to insert a signature with the same execution transparent context. A verification system finds the marker, identifies the execution transparent context of the marker, identify the execution transparent signature, and uses the execution transparent context system to then extract the signature from the execution transparent signature. That signature may then be used to verify that the file has not changed since it was signed.
