Win7 x64, Java 7u3 x86
Running Kojo JAR installer.
If Defense+ is in in Inactive or Learning mode - all goes okay: Windows asks for UAC Escalation and then installs application.
If Defense+ is in Clean PC mode, then it asks about the program (which user can classify as Isolated or system but neither as Trusted nor as Installer, which it was) and after that - freezes. CFP.EXE takes 100% CPU single-thread (33% on 3-core CPU), Comodo GUI became partially unresponsible, UAC escalation is not asked for, installer delasys for long and then reports it was run without admin priveleges.
