Trojan.KillAV.RS is a Trojan which hampers the security of the system by stopping verification of files. It deletes the cryptographic service (cryptsvc) built within the Windows OS; technically, this halts the verification of digital signatures. Also affected are Windows Updates and firewall settings due to removal of cryptsvc. It also takes several screenshots of the desktop, browsers, Fax and printers operations which are then passed on to remote locations on the Internet. It usually affects game.exe files and gathers information from them to be sent across to remote computers. This Trojan also affects the dynamic link libraries (dll) files by increasing the memory taken up by them on the system.
