is an anti-spyware tool intended to supplement your anti-virus program. The version of Windows Defender included with all versions of Windows 7
is part of the operating system so it cannot be uninstalled
but it can be disabled and it's service turned off.
Microsoft recommends that you schedule a daily Quick Scan
to check the areas of your computer that malware is most likely to infect.
Windsows Defender incorporates other features and tools such as Software Explorer
which allows users to view detailed information about programs that are running on their systems. It can also be used as a startup programs manager or as a replacement for the Windows Task Manager. Software Explorer can monitor:
- Startup programs, which run automatically when you start Windows.
- Programs currently running on the screen or in the background.
- Network-connected programs or processes that can connect to the Internet, or network.
- Winsock service providers, which perform low-level networking and communication services for Windows and programs that run on Windows.
However, if you're using another effective anti-malware scanner such as Emsisoft Anti-Malware
or Malwarebytes Anti-Malware
, there's not much point in keeping Windows Defender enabled.SpywareBlaster
is a program that restricts the actions of potentially dangerous sites
by adding a list of sites and domains associated with known spyware, advertisers and marketers to the browser's "Restricted Sites Zone". SpywareBlaster prevents the installation of ActiveX
-based malware, browser hijackers, dialers, and other potentially unwanted software and blocks tracking cookies
. SpywareBlaster also includes the ability to keep encrypted backup copies of the Hosts file
so if its altered by malware infection, you can easily restore a good backup copy.
Unlike many other security tools, SpywareBlaster is not intrusive as it does not run in the background
...it focuses on prevention
and passive protection
without utilizing unnecessary running processes or consuming system (CPU, memory) resources. The program only requires installation and then enabling of all protection. After that you only have to check periodically for database updates using the built-in "Check for Updates
" feature and then enable all protection again. Since SpywareBlaster does not use a real-time protection module, it supplements your existing security software without causing any conflicts. SpywareBlaster can be used with Internet Explorer and many other popular browsers such as Mozilla Firefox, Google Chrome, Netscape, Seamonkey, Flock and several more (see here
).How does SpywareBlaster actually work
? It adds sites to the restricted zones by adding the domain as a subkey under the registry key: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains. A dword is then added to that domain named * and given a hex value of 4 to specify that it is part of the Restricted Sites Zone. More specifically, Spywareblaster sets the "killbit" on the CLSID (Class ID)
of known spyware. Every program has a CLSID that is unique to the type of program. Once Spywareblaster enables (writes) those killbits they are "locked in" and any identified spyware cannot be opened. Spywareblaster writes these killbits in and then stays off until you need to re-write them again with an update. Why is all this important
? Some types of malware are known to alter Trusted Zones, Ranges and ProtocolDefaults set for a browser.
