Comodo won't let me download TDSSKiller

Any tips? I have tried turning Comodo off, but it still wont let me. Same if hips are off.

Also if Comodo is turned off. It needs to be on, for my computer to work. As won’t load any programs etc

What configuration are you using? Proactive Security with D+ set to Paranoid?

Is TDSS Killer the only program you cannot download? Are there specific programs you cannot run or is it impossible to run any program?
