And while most of the Internet infections have a specific criminal task that they are specialized in, the representatives of the Trojan Horse family are very versatile. These threats can perform different criminal tasks depending on what exactly the crooks want to achieve with them. That’s why you can never be sure what kind of damage such an infection may cause. In some cases, the Trojan-based virus may be programmed to corrupt your system, in others, it may damage your data, target your personal information, steal your passwords or banking details and launch hidden harmful processes in the background of your OS. There are also instances where the Trojan may be set to spy on its victims and to blackmail them. It is also not excluded that such a malware virus may be used for different actions of fraud, distribution of spam, other viruses and different scam campaigns.
