Its goal is to make sure an affiliated core infection persists inside a target system and isn’t impeded by security tools. To this end, the Trojan prevents a victim from opening popular antimalware suites. An annoying byproduct of this routine is the display of a popup alert reading, “The requested resource is in use”.

The other has to do with protecting various malicious programs against being stopped or eliminated.
