Threat risk: Severe Risk
Severe risk threats are typically installed without user interaction through security exploits, and may allow an attacker to remotely control the infected machine. Such threats may allow the attacker to install additional malware and use the compromised machine to participate in denial of service attacks, spamming, and bot nets, or to transmit sensitive data to a remote server. The malware may be cloaked and not visible to the user. These threats severely compromise the system by lowering security settings, installing ?backdoors,? infecting system files, or spreading to other networked machines.
