2. Adware Usually this term is referred to a program code implemented into freeware programs which perform forced display of advertisements to a user However sometimes such codes can be distributed via other malicious programs and show advertisements in Internet browsers Many adware programs operate with data collected by spyware Jokes Like adware this type of malicious programs does not deal any direct damage to the system Joke programs usually just generate message boxes about errors that never occurred and threaten to perform actions which will lead to data loss Their purpose is to frighten or annoy a user Dialers These are special programs which are designed to scan a range of telephone numbers and find those where a modem answers These numbers are then used to mark up the price of telephoning facilities or to connect the user to expensive telephone services All the above programs are considered malicious because they pose a threat to the user s data or his right of confidentiality Programs that do not conceal their presence distribute spam and different traffic analyzers are usually not considered malicious although they can become a threat under certain circumstances Among other programs there is also a class of riskware programs These were not intended as malicious but can potentially be a threat to the system s security due to their certain features Riskware programs are not only those which can accidentally dama

Checksums uniquely identify signatures which preserves correctness of virus detection and neutralization The Dr Web virus databases are composed so that some entries can be used to detect not just specific viruses but whole classes of threats Origins Tracing On completion of signature analysis the Dr Web use the unique Origins Tracing method to detect new and modified viruses which use the known infection mechanisms Thus Dr Web users are protected against such threats as notorious blackmailer Trojan Encoder 18 also known as gpcode In addition to detection of new and modified viruses the Origins Tracing mechanism allows to considerably reduce the number of false triggering of the heuristics analyzer Objects detected using the Origins Tracing algorithm are indicated with the Origin extension added to their names Execution emulation The technology of program code emulation is used for detection of polymorphic and encrypted viruses when the search against checksums cannot be applied directly or is very difficult to be performed due to the impossibility of building secure signatures The method implies simulating the execution of an analyzed code by an emulator a programming model of the processor and runtime environment The emulator operates with protected memory area emulation buffer in which execution of the analyzed program is modelled instruction by instruction However none of these instructions is actually executed by
