Antivirus/Antispyware:  

You certainly don’t have to worry about viruses and other malware once you’ve installed BitDefender (our #1 pick in standalone antivirus software). You can work, play, bank, shop, download and share with confidence while BitDefender Total Security keeps you completely protected.

The kernel-level antivirus protection scans all internet and messaging (including IM) traffic, and in real-time. But BitDefender doesn’t just rely on up-to-date virus definitions. Total Security utilizes several advanced heuristic technologies to proactively detect and deter even the most recent stealth malware.

Total Security now features Active Virus Control, a cutting-edge technology that locates new types of viruses that are specifically designed to go unnoticed by traditional virus detection software. Active Virus Control continually monitors all application activity, analyzing file behavior and malware-esque activity, detecting dormant viruses just waiting to release their fury.

Firewall:  

Not only does BitDefender Total Security 2010 feature a firewall, but it hosts a highly advanced and flexible firewall. The 2-way firewall helps protect your computer with automatic adjustments to suit your location. This flexible firewall also includes a Wi-Fi monitor that detects and prevents prohibited access to your Wi-Fi network from intruders.

New intrusion detection from BitDefender prevents attempts made by intruders to infiltrate your PC and adjust your important registry entries or system files. Furthermore, the software warns you if/when attacks are attempted involving DLL code injection.
