Alright, so I'm generally able to resolve minor virus issues on my own, but this one has me completely stumped.

I'm running Windows XP on a 5 year old Dell Inspiron 700m, and use Firefox 3.6.3 as my primary browser.

I've been having trouble for the past week or so. Generally I can open Firefox and it will go to my homepage (Google) as it should, although occasionally it will open another page entirely. I can manually enter a web address, and Firefox will take me to it. However, if I use a search engine (tested on Google and Yahoo) clicking on any of the results directs my browser to a variety of different sites. Occasionally these sites will be accompanied by dialogue boxes as well.

I'm not sure if these are related, but I am entirely unable to access Gmail. Whether I attempt to go there through typing the address into my nav bar, or through the link on google's homepage, it goes to:
hxxps://www.google.com/accounts/ServiceLogin?service=mail&passive=true&rm=false&continue=http%3A%2F%2Fmail.google.com%2Fmail%2F%3Fui%3Dhtml%26zy%3Dl&bsv=1eic6yu9oa4y3&scc=1&ltmpl=default&ltmplcache=2 instead. Also, while trying to test whether it was a google-specific or more general problem, I ran into this error while attempting to access Bing.com:
ERROR
Cache Access Denied

While trying to retrieve the URL: hxxp://www.bing.com/

The following error was encountered:

* Cache Access Denied.

Sorry, you are not currently allowed to request:

hxxp://www.bing.com/

from this cache until you have authenticated yourself.

You need to use Netscape version 2.0 or greater, or Microsoft Internet Explorer 3.0, or an HTTP/1.1 compliant browser for this to work. Please contact the cache administrator if you have difficulties authenticating yourself or change your default password.

I've ran SpyBot Search&Destroy, Malwarebytes, and Backlight attempting to track down the cause of this, with no luck. I did track down a few bits of spyware and adware, but nothing too exotic; all of these have been removed. Unfortunately, I did not document what I had been infected with.

Thanks in advance for any help,
-Christian

I used the TDSS removal tool. It identified one file in a drivers folders as being infected with the TDSS rootkit. Unlike the instructions, I was never prompted to type "delete," but instead to simply press "y" to reboot the system and remove the infection. I then followed the guide's recommendation to run Malwarebytes, which did not detect any infected files. I then opened Firefox to attempt to verify that my problem had been resolved. I attempted to open Gmail, which resulted in the same error I mentioned in my first post. I then attempted a variety of searches, all of which resulted in redirects.

Thank you for your help, I'm open to any further suggestions.

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/324396/rootkit-infection/ 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.

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