Hi,
It’s not as simple as connect the wire and off you go these day’s. The internet is a weird and wonderful place as long as you can control what you do, that’s why you need to protect yourself. These can be done in a number of very simple steps. These steps will get you started but you should always try to be smart when your surfing the net!
Even you didn’t connect your Desktop, you need an Anti-Virus scanner. Your computer can become infected with “viruses”. These are little files or codes that have been written to ruin your computer! That’s why they must be stopped, Choose a best Antivirus and check and use it.
It is again another line of defense against the number of ways your computer can be attacked. In simple terms it blocks other computers and programs from 
connecting to you and playing with your stuff. Think of it as an internet wall of fire, where you allow what can pass through.
Watch what you download and accept to save to your PC, sometimes people can send you files in e-mails. They look but when you run them they will install something onto your PC and leave you upset and distraught.
That’s pretty much it to get you going. If you think something doesn’t look right, it probably isn’t. Hopefully this will get you going to start with, Good Luck and Safe Surfing.
