experienced similar problems with my old and overstuffed Dell 4100 800mHz, 512 MB, XP Pro but not a newer notebook with Vista.
I'm not really impressed with Checkpoint for promoting this product without warning those with older systems to stay clear, but I have set the program to not load at startup and start it manually when the other programs and services have loaded.
Works well from a time standpoint, but not sure what kind of security compromise this is.
It also does seem to slow down programs loading after startup, but nothing I can't live with.
Just the industry's way of making sure we buy new hardware I guess.
