PC Tools Internet Security Suite is a complete Internet security suite that offers powerful Anti-Spyware, Anti-Virus, Firewall and Spam protection in one application. It detects, removes and blocks all types of Spyware, Adware, Viruses, Trojans, Worms, Keyloggers and other threats.

PC Tools Internet Security includes both anti-spyware and anti-virus protection and has the most advanced update feature that continually improves its Spyware and Virus fighting capabilities on a daily basis. As threats gets more complex to avoid detection, PC Tools Internet Security responds with new technology to stay one step ahead.

PC Tools Internet Security is advanced technology designed especially for individuals, not experts. It is automatically configured out of the box to give optimal protection with limited interaction so all you need to do is install it for immediate and proven ongoing protection.

We've done the research so you don't have to; the advanced OnGuard technology only alerts you on a true Spyware, Virus and Firewall activity while also filtering emails for spam. This is significant because you should not be interrupted by cryptic questions every time you install software, add a site to your favourites or change your PC settings. Such messages can be confusing and may result in undesirable outcomes such as program errors, lost favourites or even spyware and viruses being allowed to install on the system.

The latest 2010 includes ThreatFire pro-active intelligence, improved rootkit detection, a web browser guard, improved firewall and better anti-spam support.
