[. . . ] In the case of a manipulation of the host file, a specific manipulation of a system is carried out with the aid of a Trojan or virus. The result is that the system can now only access fake websites, even if the correct web address is entered. Phishing Phishing means angling for personal details of the Internet user. Phishers generally send their victims apparently official letters such as emails that are intended to induce them to reveal confidential information to the culprits in good faith, in particular user names and passwords or PINs and TANs of online banking accounts. With the stolen access details, the phishers can assume the identities of the victims and carry out transactions in their name. What is clear is that: banks and insurance companies never ask for credit card numbers, PINs, TANs or other access details by email, SMS or telephone. They change their own programming codes - and are therefore very hard to detect. Program viruses A computer virus is a program that is capable of attaching itself to other programs after being executed and cause an infection. In contrast to a worm, a virus always requires a program as host, where the virus deposits its virulent code. The program execution of the host itself is not changed as a rule.

They attempt to update already installed spy programs and reinstall deleted spyware. Script viruses and worms Such viruses are extremely easy to program and they can spread - if the required technology is on hand - within a few hours via email round the globe. Script viruses and worms use one of the script languages, such as Javascript, VBScript etc. , to insert themselves in other, new scripts or to spread themselves by calling operating system functions. This frequently happens via email or through the exchange of files (documents). A worm is a program that multiplies itself but that does not infect the host. Worms are often the only possibility to infiltrate any kind of damaging programs on systems with restrictive security measures. Spyware Spyware are so called spy programs that intercept or take partial control of a computer's operation without the user's informed consent. Spyware is designed to exploit infected computers for commercial gain. Trojans include programs that pretend to have a particular function, but that show their real image after execution and carry out a different function that, in most cases, is destructive. Trojan horses cannot multiply themselves, which differentiates them from viruses and worms. Most of them have an interesting name (SEX. EXE or STARTME. EXE) with the intention to induce the user to start the Trojan. [. . . ] The action mode of the Realtime Protection is set in the configuration under Realtime Protection > Scan > Action on detection.
