Why are no signature based programs able to detect all?
Signature based anti-virus and anti-monitoring programs provide efficient protection against known malicious programs. They can detect viruses, Trojans, key-loggers, all of which have been documented and published, but they are unable to detect all keystroke monitoring programs. Why is this? Because the utilities are capable of detecting ONLY KNOWN monitoring programs, which have been analyzed by their developers, and only then the electronic or coded signatures of these malicious programs can be included into the appropriate data bases. But there is another group of monitoring programs, which is more dangerous for privacy – UNKNOWN programs. They are developed in limited quantity (often only one copy) for solution of the concrete task (intelligence gathering software, surveillance software, eavesdropping software, data interception software, industrial espionage software, economic espionage software, competitor intelligence software, foreign intelligence software etc.). These unknown
