I was browsing on yahoo and heard an unusual beep. Immediately I started getting pop ups so I suspected something and shut down internet explorer and ran AVG free version. The scan showed I was infected with Trojan Crypt.ANVH. AVG could not completely remove it. I did a windows restore to an earlier time. I had recently changed the password on the router, but after the restore, I.E. could not connect and the diagnostic tool said something about winsock. I'm not sure if this is related at all. The router works fine for everything else, so I think it is the infected machine where the problems lies. I tried running a few diagnostics dowloaded from another machine and installed via USB stick. Malware bytes found nothing. I next ran combofix. This said I was infected with the zero access rootkit. It ran it's course and deleted/changed some system files. After running it several times and re-booting, I still cannot connect to the internet via I.E. Everytime I run CF it says the machine is infected with Zero Acccess, but doesn't make any changes. I also ran tdsskiller, it found nothing and aswMBR, it also found nothing. What can/should I do next? I am running Windows XP home. Thanks.

Follow the directions/procedures stated at Preparation Guide, Before Using Malware Removal Tools and Requesting Help - http://www.bleepingcomputer.com/forums/topic34773.html and include your CF log, in addition to the logs specified in the Prep Guide.

The Guide has a link that will take you to the proper forum for malware log topics.

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/topic441263.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.
