Prevent Hacking

I read the article How to Prevent Hacking of your PC? by Jay HS. Jay says the key to keeping hackers off your computer is to install a anti-virus, firewall and anti-spyware solution. Another way to stay hacker free is to avoid strange emails and attachments from people or companies you don't know and visiting cracks, warez, and keygen websites. If your computer is acting strange, such as pop-up ads appearing, shutting down applications, slow or nonexistent Internet connections, chances are your computer is infected.
