The most important thing for Internet security is to have a router. If you use a router then get the free anti-virus %26 firewall. It should do the job.

I use zone alarm firewall and norton anti-virus, but next year when my subscriptions run out I will download the free package from my internet provider.
You do not need to download pirated (stolen) software for protection. Nor do you need to purchase anything. There are plenty of free and legal and very effective solutions for you.

An excellent free firewall is Comodo Personal Firewall. It can pass firewall "leak tests" that even most of the "paid-for" firewalls cannot pass.
