TrojanDownloader:SWF/Esaprof!pz Detection Overview

The TrojanDownloader:SWF/Esaprof!pz detection you can see in the lower right side is demonstrated to you by Microsoft Defender.

The exact TrojanDownloader:SWF/Esaprof!pz malware is a really unpleasant thing. This malware is created to be a sneaky burglar, which functions as a remote-access tool. When you provide somebody remote access willingly, it is OK, however, Esaprof will not ask you if you want to provide it. After connecting to your computer, criminals are free to do whatever they want – grabbing your files, reading your messages, gathering personal data, et cetera. Backdoors usually bring a supplementary stealer – the virus that is developed to collect all possible data about you. However, far more widespread use of the backdoors is forming the botnet. Then, the network of corrupted computers can be used to conduct DDoS attacks or to inflate the survey results on various sites.

Shortly about backdoors

Backdoors are viruses that may acquire both separated and integrated forms. Once you can uncover that an official program from a well-known developer has a functionality that makes it possible for someone to connect to your computer.
