I know a fellow who uses deep freeze and is very happy with it, the only way i know to beat it is to boot from a cd, which really beats any security i know of. It is quite popular with educational institutions (several high schools and post secondary insttituitions in my area use it) .
antifirefox -- that will only work on a trial version AFAIK
As to the antipoint status i guess someone doesn't like what you posted sysadmin1984 (i negged the two useless answers) , don't know why its a valid question about a widely used security product , i guess you can't please every one .
