Microsoft Security Essentials has received great recognition for the
protection: the VB100 award from Virus Bulletin Ltd., Checkmark
Certification from West Coast Labs, and certification from the ICSA
Real-time protection means addressing potential threats before they
become problems. Alerts notify you when spyware, viruses, or other
malicious software attempt to run or install on your PC, and suspicious
files and programs are prevented from opening.
Microsoft Security Essentials offers complete system scanning
capabilities with both scheduled and on-demand scanning options to
provide an extra level of confidence. Scheduled scans are turned on by
default and configured to run weekly at 2 a.m. when the system is likely
idle. There are three scanning options:
* Quick scan. On by default, a quick scan rapidly checks the areas
malware is most likely to infect, including programs running in memory,
system files, and the registry.
* Full scan. A full scan checks all files on the PC, the registry, and all currently running programs.
* Custom scan. A custom scan allows you to scan only the areas you select.
You can choose when you want a scheduled scan to run, view the scan
results before cleaning, or run a scan on demand. If the PC isnt turned
on when the scan is scheduled to run, Microsoft Security Essentials
will start the scan at the first opportunity once the PC is awake and
When Microsoft Security Essentials determines a possible threat on your
PC, alerts notify you of the threat. Threats are categorized as Severe,
High, Medium, or Low, and you can choose whether to ignore, quarantine
or remove the item from the system.
* Quarantine. Microsoft Security Essentials blocks less severe threats
and moves them to a quarantined queue where you can elect to restore or
permanently delete them. By placing an item in quarantine, you can test
the effect of the items removal before deleting it from the system.
* Remove. This action permanently deletes the item from the system.
* Allow. This action stops Microsoft Security Essentials from detecting
the item in future scans by adding it to the Allowed Items list. You can
remove items from the Allowed Items list at any time.
Windows Firewall integration
Having an active firewall is part of securing your PC. During setup,
Microsoft Security Essentials scans the PC to determine if a firewall is
active on the PC. If no firewall protection is present, youll be given
the option to turn on Windows Firewall.
Dynamic signature service
Protection needs to be up-to-date to be effective. Dynamic signature is a
way to check whether a suspicious program is bad or not. Before a
suspicious program runs, Microsoft Security Essentials pretends to run
it to determine what its going to do. This gives programs special
signatures that are checked against our database of good and bad
programs. Programs are watched even after they are approved to make sure
they dont do anything potentially harmful like make unexpected network
connections, modify core parts of the operating system, or download
Rootkits are particularly difficult types of malware to protect against,
and Microsoft Security Essentials includes a number of new and improved
technologies to address rootkits and other aggressive threats.
* The kernal is at the heart of your PCs operating system. Microsoft
Security Essentials monitors it to see if there are any attacks or
* Rootkits use stealthy methods to hide themselves and Microsoft
Security Essentials has the latest anti-stealth technology to uncover
them. For example, direct file system parsing helps find and remove
malicious programs and drivers that rootkits try to sneak in.
Protection against real threats, not good software
Microsoft Security Essentials helps block bad software. We keep a list
of the most popular websites and downloads on the Internet and use it to
test our antimalware definitions and updates before they get to you.
This helps us make sure that the protection we offer really keeps your
PC safe, and not blocked.
