I have a teenage that is doing things on sykpe that she shouldn't be doing and I would like to know how to block it? Thanks!

It would be best to do this through a router - either by blocking the Skype specifically, or by setting time restrictions limiting access to specific times of the day. The Motorola DOCSIS 3.0 is most likely your modem and the modem (unless integrated with a router) does not allow you to customize access. You can use parental control software, or the firewall on her computer, however, using parental control or the firewall would have to be done on every computer in the house. That may or may not be a problem.

Many ISPs provide parental control software for free. Also, Windows 7 has Parental Control capabilities built in.

And block skype with firewall

Also, kids should never have an administrator account. So for sure, you should change her account to a Limited or Standard account, if not there already.

And, while it may be too late now (for peace in the house) kids should never have a computer with Internet access in their room. Kids' computers should always be located in an open, central location in the home where parents can see what they are up to. While we may trust our kids, we cannot always trust each of their friends.

Although a bit drastic, you can always remove the power supply to the modem when you go to bed.

In any case, for us to help, we would need more specific information about your computer and networking hardware, and your OS.

The problem is its her laptop, she is 17 but she always talks to stranger on the internet. Her OS is Windows 7 home premium. I know her password to her laptop so is there a way to block it via firewall?

I posted that information above. To narrow the search, enter the firewall name in the search parameters.

For example, block skype with Windows Firewall

You might also call your local police and ask if they have any advice or information they share with your to scare some sense in your daughter about online predators. Maybe talk to her school too and they can do something school-wide. At the very least, you need to talk to her and tell her (1) you are truly scared for her safety and (2) that she must NEVER - as in NEVER EVER give out any personal information such as full name, phone numbers, school, town, address or the like. And if she has any siblings, she needs to know that chatting with strangers over the Internet puts them at risk too.

Predators are very smart and clever and know exactly what to say to put their "targets" at ease.

There is no such thing as "it will not happen to me" when it comes to the Internet. Of course all teens are invincible, right?

In the case of 'Windows Firewall', try the following (will need to be an administrator):

• In START button search box, type --> firewall.
• Select link 'Allow a program through Windows Firewall'.
• Click 'Change settings' and uncheck 'Skype'.

Talking to this child is like talking to a brick wall! She don't listen to either of us (mom or me). I know how stop it all together and that is to change the password on the wireless. She has just the window firewall so I went into the advance setting and created an in/out bound rule for Skype (not to allow either traffic). Then I started up Skype on her computer and it would not connect to Skype's home page. The next thing I will do is find the web cam exe file extension and block that if I can. Thanks for all the comments

I hear you. My kids are all grown now with kids of their own. Grandchildren are parents revenge.

The problem is, your child will simply go you her friend's house, or some other place so you still need to keep pounding in the security issues and pray something sticks.

Good luck.
