I think I am virus free now but a month ago I got the following viruses on a Win XP 32 bit SP3 pro computer with IE8:

Rootkit.Boot.Pihar.b
Win32/Orsam!rts
DOS/Alureon.H
Win32/Alureon.FK
Win64/Alureon.gen!J
Win32/Alureon.gen!AD
Win64/Alureon.gen!F

After running TDSSKiller, Malwarebytes, MS Security Essentials, Microsoft Sweeper, Kaspersky Emergency Disc 10, aswmbr, Farbar Service Scanner the only discernible problems I have left are in Event Viewer:

1. Error: The IP address lease 192.168.1.2 for the Network Card with network address 000CF183A78B has been denied by the DHCP server 192.168.1.1 (The DHCP Server sent a DHCPNACK message).

2. Warning: TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts.

(and the occasional warning: The redirector failed to determine the connection type.)

When I reset TCP/IP and Winsock or flush the dns the DHCP error goes away for one reboot but then comes right back. I have updated the network card driver but I haven't removed and reinstalled TCP/IP yet...which I guess is the next logical step.

I also get a lot of Security Alert popups in Internet Explorer which say: "You are about to view pages over a secure connection" even when I'm NOT going to s secure (https) site. In fact I get the popups on the bleeping computer site.

Another thing that is strange is that when I right-click on my hard drives in My Computer it takes a good 10 seconds for the context menu to appear the first time I try it. If I do it again right away it pops up immediately like it always did previously.

Does anyone have any suggestions about how to proceed?

Thanks in advance for any help/suggestions!

Please follow the instructions in ==>Malware Removal and Log Section Preparation Guide<==.

Once the proper logs are created, then make a NEW TOPIC and post it ==>HERE<== Please include the link to this topic in your new topic and a description of your computer issues and what you have done to resolve them.

If you can produce at least some of the logs, then please create the new topic and explain what happens when you try to create the log(s) that you couldn't get. If you cannot produce any of the logs, then still post the topic and explain that you followed the Prep. Guide, were unable to create the logs, and describe what happens when you try to create the logs.

Once you have created the new topic, please reply back here with a link to the new topic.

Most importantly please be patient till you get a reply to your topic. If you receive a reply from the HelpBot, then please follow the instructions outlined in the helpbot's post.

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.
