Rogue programs usually emerge with interventions by Trojans, but the main task of these programs is not to infect computer by dropping harmfull viruses. The main objective - making user to make money transfer via insecure payment webpage. The criminals will not only receive a cash transfer, but will possess your personal details with the possibility of using them wherever credit card information is required.
In order to deceive the consumer, various techniques based on user scare tactics are used. Criminals are attempting to convince victim that his computer system contains various threats and can be removed with the help of fake AV, that is being advertised. The removal function will not be activated until licensed version of the rogue program is purchased. However, the licenses of rogue programs are meaningless, because viruses that pose a serious danger to the computer will not be eliminated.
The following techniques are used to scare user into purchasing fake AV:
- Informational-warning messages, also known as "fake alerts", stating that computer system is allegedly infected;
- Exaggerated PC scan reports, claiming the presence of trojans and viruses;
- Online computer scanner, stating that the hard drives contain Trojan and viruses;
- Windows Security Center, which is responsible for system safety and protection, is faked for promotional purposes (more);
- Replaced desktop background, stating "Your computer is in danger".
