RUBotted is a program that monitors and analyzes the system for specific malicious files known as bots. If it detects any, delete it through the HouseCall tool.
The bots are files that attempt to take control of the PC to perform certain tasks without the user knowing. For example, they can be used to steal information, to send spam, to attack servers (in conjunction with other infected users), etc.
Among the bots that this antivirus detects are the following: ZBOT / ZeuS whose purpose is to steal bank accounts, KOOBFACE a botnet (or zombie) that makes DDoS attacks, WALEDAC a bot that sends spam; Along with variants of these.
RUBotted is compatible with traditional antivirus such as Avast, Avg, etc., so it can be used as a complement to these, with the advantage that it is able to detect bots that other antivirus programs do not detect; It also consumes few resources.
Trend Micro RUBotted 2.0 Beta is the latest version of this anti-malware program that you can download free of charge. Works for Windows 7, Vista and XP.
