Remove Civcat. Description and removal instructions

Title: Civcat
Type: Backdoors	Severity scale: (73 / 100)

Civcat is a backdoor that gives the attacker unauthorized remote access to a compromised computer. Once executed, the parasite installs itself to the system by reconfiguring a particular Windows system service. Then it contacts predetermined remote hosts and awaits for specific commands from the attacker. The intruder is allowed to retrieve system and network information, download and upload arbitrary files, execute files and run programs, alter the backdoor's configuration and load specified DLL libraries. Civcat automatically runs on every Windows startup.
