Disclosed is a portable security device and method for detection and treatment of computer malware. An example method includes performing a malware detection experiment by the security device on the computer by simulating a connection to the computer of a simulated data storage device containing a predefined set of data. The method further includes determining if there are any modifications in the set of data contained in the simulated data storage device after termination of the malware detection experiment. The method further includes, based on whether there are any modifications in the set of data, determining whether to perform one or more subsequent malware detection experiments by the security device on the computer. In one example aspect, each of the one or more subsequent malware detection experiments are configured to simulate a different connection to the computer of a different simulated data storage device containing the predefined set of data.

A server-based system for generation of heuristic scripts for malware detection includes an automatic heuristics generation system for generating heuristic scripts for curing malware infections; a log database containing logs of events from user computers, including detection of known malicious objects and detection of suspicious objects; a safe objects database accessible containing signatures of known safe objects; a malicious objects database containing signatures of known malicious objects. The system retrieves suspect object metadata from the log database and generates the heuristic script based on data from the safe and malicious objects databases. For multiple computers having the same configuration and having the same logs, only one log common to all the multiple computers is transmitted and only one heuristic script is distributed to the multiple computers. A different and specific heuristic script is distributed to those computers that have a different log than the common log.

Disclosed are systems, methods and computer program products for treatment of malware using an antivirus driver. In one aspect, an example method includes performing, by an antivirus software, an antivirus scan of the computer; detecting, by the antivirus software, a malicious object on the computer; formulating at least one task for treatment of the detected malicious object; configuring and activating on the computer an antivirus driver of the antivirus software to execute the at least one formulated task for treatment of the detected malicious object; and rebooting the computer by the antivirus software, whereby upon rebooting of the computer the antivirus driver is loaded by the operating system of the computer to execute the at least one task for treatment of the detected malicious object.

Disclosed are system, method and computer program product for assessing security danger of software. The system collects information about a suspicious, high-danger software objects, including one or more malicious characteristics of the software object, security rating of the software object, and information about one or more security rating rules used in assessing the security rating of the software object. The system then determines whether the suspicious object is a clean (i.e., harmless). When the suspicious object is determined to be clean, the system identifies one or more unique, non-malicious characteristics of the software object and generates a new security rating rule that identifies the software object as clean based on the one or more selected non-malicious characteristics. The system then assigns high priority ranking to the new security rating rule to ensure that the rule precedes all other rules.

The system then identifies in the selected group of programs a plurality of only malicious programs or the plurality of only safe programs based on the problematic security rating rule and at least one different security rating rule. The system then generates a behavior model script based on the problematic security rating rule and the at least one different security rating rule and executes said behavior model script during antivirus analysis of said analyzed program to detect a computer malware in said analyzed program.
