RATs are programs that allow control of other, infected computers remotely through a separate system. Cyber criminals use distributed malware to extort money from people and use stolen information to generate revenue in various ways. Installed malicious software could be used to control the infected system remotely, lock (encrypt) files and force victims to pay ransoms, steal personal details and use them to generate revenue, etc. For example, cyber criminals can design them to infect the victim's computer with ransomware, a RAT (remote access trojan), banking malware, and so on. Many malicious programs can be distributed through trojans. Trojans often cause chain infections (download and install other malware). Typically, malicious programs such as Vigorf download or install other malware, use the infected computer to perform click fraud, record keystrokes and information relating to victims' browsing habits, or provide cyber criminals with access to the infected computer and allow them to perform malicious actions.

In any case, if detected, this malicious software should be removed immediately. It is not certain exactly how this trojan affects infected computer systems, however, it could be designed to perform a number of different actions.

Vigorf is the name of a threat that most virus detection engines recognize as a trojan, also known as Trojan Win32/Vigorf.
