- If it has been downloaded from some shady third-party software download site.
- If you have received it in the form of an e-mail attachment or a URL in your e-mail inbox.
Victim reports indicate that this virus uses files that are masked as cracks or some other kind of downloadable files on software download sites, for example:
- Patches for programs or games.
- SFX (self extracting) or regular archive files.
- Cracked applications or portable apps.
- Crack-fixes or activators for software or games.
- Keygens or key generators.
Another infection scenario maybe if you have received the virus in the form of an email attached document, that very often pretends that it is extremely important and you must read it, for example:
- Invoice files.
- Receipt documents.
- Work-related documents.
- E-Tickets of some kind (flights, train, events).
Such files have malicious code embedded them that may trigger the following infection process once you download the file, open it and enable its content:

When infection with this particular virus takes place on your device, the first thing the virus may do is it may connect to a remote server. From it, the RRBB virus may initiate a silent download of the payloadmodule files it uses. These malicious files may be located in the following directories:
- %Temp%
- %System%
- %AppData%

- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
