After the release of the Windows 7 operating systemthose hackers who earned by writing common viruses, has become much more difficult. The reason for this lies in the special module of the new OS called "Defender Windows 7".
In contrast to the weak programs designedto ensure the security of previous versions, in Windows 7 for the first time anti-spyware and anti-virus protection is built right into the operating system and starts with it. This is especially important, considering that unwanted and spyware can quite easily get to your PC from the Internet, or through such infected media as CD / DVD and flash drives, and most such malicious programs begin their activities immediately after the next reboot of the computer.
Windows Defender has two frontiers of defense and the main attacks on the computer prevents the first frontier - real-time protection.
This function warns the user how toonly spyware or any program that has information that it performs unwanted actions, starts to install into the system, or simply tries to start.
If an alarm has been triggered, depending on the notification level that is set in the OS, several actions will be available to the user.
The first is to quarantine. A malicious program is moved to quarantine and it is prohibited from running until it is restored or deleted.
To delete or, conversely, restorequarantined files, start the defender with the "Start" button, then select "All Programs", then click on the "Windows Defender" shortcut.
In the window that opens, go to the Tools menu and click on the item designated as "Quarantined Objects".
Here you can view all the storedobjects and determine suitable actions for them. If you are going to delete all files, click the "Delete all" button. If any of them may be useful for you, select the "Restore" button for each item in the list, and for those that are not needed, you must click the "Delete" button.
The second item is to remove the program. If you know for sure that the file you are running may contain spyware, then you should immediately remove it. This menu item allows you to do this safely.
The third point is to allow execution. With this button, you can add a program that the Windows Defender defined as spyware, to the exclusion list. You will not see any more warnings about this software, so click the "Allow" button only if you are 100% sure of your decision.
An experienced user can choose those programs or settings that, in his opinion, Windows Defender should check.
The second OS defense boundary is scanningsystem files to monitor their status and versions. In the scan settings, the user has the scan schedule settings, options for automatic or manual removal of the detected spyware. In any case, it is recommended to change something there only to those who know exactly what they are doing.
From time to time, "Windows Defender" connectsto the network to check for updates in the so-called "list of definitions." In this list, OS developers are constantly adding newly discovered spyware and other unwanted programs. Updating the list occurs through the Windows Update Center, along with the parallel update of other components of the operating system.
And for those who believe that there is not much securitySometimes, the utility provides the ability to configure the scan in such a way that it is preceded by updating the definitions for the most complete and reliable scan.
