As Mr. Deeds would say, "My Bad" I didn't read up on the program and in truth I know nothing about it. I assumed that this program was a Trojan. The fact that is a commercial program installed through administrator privy makes it even WORSE. There are a lot of paranoia adds that directly sabotage the trust between spouses. They show a picture of one spouse doing naughty things that catch the attention of another spouse and make them question why someone spends so much time online. They are as bad as those X10 adds.
A kid wanting access to something is definitely a possibility. Unless they are like 4 and play Bob the Builder games all day. My neighbor’s kid is constantly trying to unlock the DVD adult codes. I don't blame the kids; I would have done the same thing. :D
The 3rd party part is scary. It would make one start to suspect everyone around him.... You definitely have to find out who did it though.
