Problem on older Dell desktop, Windows XP Home, SP3. Internet connection via Linksys Wireless-N Gigabit router. Has worked fine in the past and continues to work with other computers and devices in the house. After a malware attack (which seems to have been fixed, but maybe isn't) I cannot restore the internet connection. On the malware problem, I ran super antispyware, malware bytes, and combofix (twice). Combofix found and repaired a rootkit problem. Now my wireless signal is strong, but get a "limited or no connectivity" error message because "network did not assign a network address to the computer." Network connection details: IP Address; subnet mask After clicking "Repair" I get "Windows could not finish repairing because the following action cannot be completed: Renewing your IP address." I have looked at various sites and blogs and tried a number of suggested fixes, including turning modem and router off and on, fixing winsock errors, running "ipconfig /renew" and other related commands, etc. Firewalls are disabled. TCP/IP is set set to obtain IP address and DNS server address automatically. When I try to access Windows Firewall settings I get error message "cannot be displayed because the associated service is not running." when I try to start the Windows Firewall/Internet Connection Sharing (ICS) service, Windows can't start it. I have now tried putting in a static IP address. This eliminates the "limited or no connectivity" problem but I still can't connect to the internet. Any help is much appreciated.

Since you don't sound sure about the infected status of your system...I suggest that you initiate a post in the appropriate forum.

Follow the instructions/guidance at Preparation Guide, Before Using Malware Removal Tools and Requesting Help - http://www.bleepingcomputer.com/forums/topic34773.html and include your latest HJT log as part of the submission.

Good luck :).

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/topic429188.html you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a MRT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the MRT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the MRT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the MRT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.

To avoid confusion, I am closing this topic. Good luck with your log.
