"Seems to work well, but with root kits you cant be sure"
It's free, doesn't need to be installed and runs quickly and easily.
Nothing that I can see.
richie58 says it didn't work. I had an almost certain root-kit grabbing my computer and when I ran Panda ARK, it behaved as richie58 describes. I reinstalled XP and no problems - Panda ARK ran. I suspect the root-kit prevented Panda from working, but any geeks out there please correct me.
