It has been more than three days...
http://www.bleepingcomputer.com/forums/topic446229.html


By uninstalling/reinstalling the network adapter driver or updating the driver or resetting TCP/IP I can make the problems go away for one reboot of the computer. The 2nd time I reboot the problems are back.

I get an occasional event that says: "The browser has forced an election on network \Device\NetBT_Tcpip_{11C9F84F-98AA-44FA-8925-FD94F886A831} because a master browser was stopped.". This seems to come in conjunction with the MrxSmb "The redirector failed to determine the connection type." warning in Event Viewer.

None of these issues keep me from connecting to the Internet or seem to slow down my computer (except for the context menu issue with my hard drives and occasionally when it takes a few seconds to refresh my Desktop icons after closing a window).

The reason I am concerned is that I have read that pieces of rootkit viruses can linger (with few obvious signs) but still open up ports that can make future infections easier. I did a full scan with Microsoft Sweeper (which apparently is a Linux boot disk anti-virus). Since it didn't find anything should I feel confident that the viruses are gone?

It would be nice to have a clean Event Viewer but if it means wiping out my system and reinstalling everything I guess I can deal with these annoyances until they get more serious.

Any comments or suggestions?

Now that your log is properly posted, 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 Malware Removal Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it 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 Malware Removal 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 Malware Removal Team members are very 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 Malware Removal 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 MRL Team member is already assisting you and not open the thread to respond.

The current wait time is 1 - 3 days and ALL logs are answered.

To avoid confusion, I am closing this topic.
