I just got a pc & I'm used to a mac so I'm lost. I'm trying to download skype onto this lap top but it's saying for the safety of the computer it wont download. Do I have to buy norton security to enable me to get skype? thanks
No, you definitely don't have to buy Norton to download or use Skype.
Try using this link to download the Skype installer: http://www.skype.com/go/getskype-full-56
If the Windows UAC (User Access Control) asks you if you want to allow that program to download/run, say yes.
Save the file from that link to your hard drive. Once the download is complete, double click on the file to run it and install Skype.
