Features and Benefits
As with other Microsoft security products, Microsoft Security Essentials uses advanced system scanning and removal technologies to help protect against software threats.
Here are some of the features within Microsoft Security Essentials:
* Real-time protection
Alerts notify you when spyware, viruses, or other malicious software attempt to run or install on you PC, and suspicious files and programs are prevented from opening. With real-time protection, Microsoft Security Essentials is less intrusive, provides better protection from constantly changing threats, and requires fewer full-system scans.
* System scanning
Full-system scanning capabilities with both scheduled and on-demand scanning options. Microsoft Security Essentials runs a quick scan as part of the setup experience to check whether the system is clean right from the start.
* System cleaning
Automates the removal process by taking the recommended action for all items detected. By default, automated scans will remove Severe and High items, although you may change default actions in the Settings tab at any time.
* Windows Firewall integration
Having an active firewall is part of securing the computing experience. As part of setup, Microsoft Security Essentials scans the PC to determine if a firewall is active on the PC. If no firewall protection is present, you will be given the option to turn on Windows Firewall.
* Live system behavior monitoring
Live system behavior monitoring uses sensors to detect suspicious process, file registry, and kernel operations to help identify new threats. New sensors can be added with each monthly update.
* Dynamic signature service
A new approach to providing the most up-to-date protection for the PC without having to wait for the next signature download. It contains additional technology to monitor for new and emerging malware and check for signature updates in near-real time.
* Rootkit protection
Live kernel bahavior monitoring. Improved anti-stealth functionality. Improved live rootkit removal through dynamic loading of a new kernel mode driver.
* Protection against false positives
* Network inspection system
Protection against network-based exploits such as the Conficker (MS09-67) and other exploits that take advantage of network vulnerabilities to infect PCs.
* Doesn't get in the way of PC performance
Doesn't carry the weight of suit products and has a much smaller download size. CPU throttling ensures no more than 50% of CPU is utilized by its activity. It uses smart caching and active memory swapping.
