Hi Ru-Lee,
I hope this gets through your translator ok. If it doesn't let me know
what language you speak and most likely I can find someone here that speaks
it.
You shouldn't have to buy anything other than maybe a good anti virus
program. There are some out there though that are free that you can use that
are supposed to be good too. First though you should make sure you have all
the critical updates from Windows Update. These are there to address known
security issues and are to help protect your system. It is also a very good
idea to either turn on the Windows Firewall, or install a 3rd party
firewall. This will help protect your system as well.
