Win32/Sirefef.DA is a terrible Trojan infection that uses multiple locations to set its interlinked copies. There is no need for all of the copies to be idle at once. Once the active copy of Win32/Sirefef.DA is spoiled, removed or is not able to run because of other reasons, one of the idle copies of Win32/Sirefef.DA would be activated. In case of detecting Win32/Sirefef.DA by running processes, idle copies would remain unnoticed. Win32/Sirefef.DA can download and install additional malware threats. Win32/Sirefef.DA can also distribute rogue security programs. Remove Win32/Sirefef.DA and all its idle and active duplicates immediately after detection.
