True Sword last was suspected as rogue in 2006. But then it was removed from all lists and participated in different tests. Now it has fullfunctional free 1 month trial. That is not the way rogue software works. True Sword seems to be quality scanner now.
Combofix is very effective and powerful. But be careful - and i don't suggest using it on XP laptops (desktops are fine). Don't know why, but it ruined several XP laptops on my experience.
