how do I set security on my DWL-952


There are 2 possible areas raised by this question. The first is a security patch needed to fix the firmware of your router, which by the way is not dwl-952. Your router is a di 954. Dwl 952 is a bundled router and network interface. The details of the firmware update are below.

Alternatively, they can also be found on the device web configuration.

The second possibility is to set the local security on your network.

From the wikipedia page:
Wireless security is the prevention of unauthorized access or damage to computers using wireless networks. The most common types of wireless security are Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA). WEP is a notoriously weak security standard. The password it uses can often be cracked in a few minutes with a basic laptop computer and widely available software tools. WEP is an old IEEE 802.11 standard from 1999 which was outdated in 2003 by WPA or Wi-Fi Protected Access. WPA was a quick alternative to improve security over WEP. The current standard is WPA2; some hardware cannot support WPA2 without firmware upgrade or replacement. WPA2 uses an encryption device which encrypts the network with a 256 bit key; the longer key length improves security over WEP.

Wireless security

Log in to your router and find the wireless security section. Set up the security model that best suits your needs and then set up your wireless network card with the same information.

Your system is infected by Sasser worm.The Sasser worm infects machines via network connections. It can attack entire networks of computers or one single computer connected to the Internet. The worm exploits a known windows vulnerability that is easily patched, however few systems seem to have this patch installed. It attacks Windows 2000 and Windows XP machines along with Windows NT and Windows Server 2003.

Utility Manager Vulnerability

How Can I Remove the Sasser worm?

Follow these steps in removing the Sasser worm.

1) Disconnect your computer from the local area network or Internet

2) Terminate the running program
Open the Windows Task Manager by either pressing CTRL+ALT+DEL, selecting the Processes tab or selecting Task Manager and then the process tab on WinNT/2000/XP machines.
Locate one of the following programs (depending on variation), click on it and End Task or End Process

avserve.exe
avserve2.exe
skynetave.exe
any process running with the "_up.exe" suffix
Close Task Manager

3) Activate the Windows XP Firewall (if running Windows XP) or another firewall to prevent the worm from shutting your system down while downloading the patches. To activate the Windows XP firewall, follow these steps.
Click on Start, Control Panel
Double-click on Networking and Internet Connections, then click on Network Connnections
Right-click on the connection you use to access the Internet and choose Properties
Click on the Advanced Tab and check the box
"Protect my computer and network by limiting or preventing access to this computer from the Internet"
Click OK and close out of the Network and Control Panel

4) Remove the Registry entries
Click on Start, Run, Regedit
In the left panel go to 

HKEY_LOCAL_MACHINE>Software>Microsoft>Windows>Current Version>Run
In the right panel, right-click and delete the following entry

"avserve.exe"="%Windir%\avserve.exe"
"avserve2.exe"="%Windir%\avserve2.exe"
"skynetave.exe"= "%Windows%\skynetave.exe"
Close the Registry Editor

5) Delete the infected files (for Windows ME and XP remember to turn off System Restore before searching for and deleting these files to remove infected backed up files as well)
Click Start, point to Find or Search, and then click Files or Folders.
Make sure that "Look in" is set to (C:\WINDOWS).
In the "Named" or "Search for..." box, type, or copy and paste, the file names:

avserve.exe
avserve2.exe
skynetave.exe
C:\win2.log
Click Find Now or Search Now.
Delete the displayed files.
Empty the Recycle bin

6) Reboot the computer and update your antivirus software, and run a thorough virus scan using your favorite antivirus program.

For Automatic Removal of Sasser, download the Symantec removal tool, you'll still need to download the patches above and install them, however this removal tool will stop the Sasser worm from running, remove the items in the registry, and delete the infected files.
