Proactive security freeze computer

Im trying to do the comodo leak test.
When i switch to proactive security as soon as i start surfing computer will freeze.
Instructions says its impossible to get 100% without using proactive security mode, how am i supposed to test for leaks if it freeze my computer ???

Are you running Proactive with D+ set to Paranoid? What OS are you on?

Also please make sure there are no leftovers of security programs you had installed in the past. A possible left over can cause all sort of “strange effects”. Please run clean up tools for all security programs you had in the past. A list can be found here at the Eset website: ESET Knowledgebase .
