Help pls! I have no idea which software to choose!

So my sister has asked me to install some form of parental control on her two computers. It seems she caught her son looking at... things. I've offered to examine all these sites for suitability and got a shocking look!!! Seeing as how he's still fairly young and has very little computing expertise, parental control should be pretty effective for a good deal of years.
I was looking at McAfee Internet Security Suite, but it doesnt talk much about its parental control system. But google recommended some following: OpenDNS (it seems not a parental control, but a great many are talking about it. Why?), SentryPC, Porn Blocker, but I have no idea which one to use though (and the way). Pretty much all it needs to do is block questionable websites, and provide some kind of whitelist thing so it won't block cracked. Any of you has experience with such kind of? Or some other nice advice? Thank you!
P.S.: We all are not savvy enough for computer so I need something super user easy...and tech support included
Oh, this is her My Computer- right click
OS: Win XP Pro SP3
Pentium (R) Durl-core CPU
E5300 @ 2.60GHz
2.59GHZ 2.00GB

OPENDNS has internet filter. The option is inside their website. You need to log in and turn the internet filter on. It is at the dashboard menu.

For simpler setup ,maybe you can try 1 of these freeware
