I installed Keirio from a PC Advisor disc which came with the latest Tricks issue. (WME) and I have never met so much trouble in all my life. I was bombarded with so many uninteligle warnings that I was thinking about getting enigma from bletchly! It also brought browsing to a virtual standstill..10 mins to get on this site for example. In the end I had to uninstall and reboot to return to some sanity. I have XP on another drive (dual boot) with firewall enabled and you would never know it was there.
