This is a generic detection for the Brontok Worm. The Brontok worm has been around since 2005 in one form or another. Most variants have the ability to disable security software and participate in DDOS attacks.
The primary task of Worm.Ramnit is to steal information from the compromised system. It does this by downloading component files that perform particular tasks. For example, one of its components is capable of stealing cookies in order to hijack banking and social media sites. Another component is capable of giving threat actors remote access to the affected system.
Worm.Ramnit arrives on affected systems via removable and fixed drives, public FTP servers, exploit kits, or bundled with potentially unwanted software. Sometimes, it can also be dropped by Virus.Ramnit.
Malwarebytes can remove Worm.Ramnit without further user interaction. However, it is also advisable to call legitimate computer technical support services should one encounter complications.
