I have an issue with some adware that I have been unable to get rid of. It started when I noticed that I was no longer able to update AVG, or Windows (No matter how I try to update I am told that I can't connect to the servers). I downloaded some new A/V programs (Avast, Anti Vir) which I was able to update but was unable to find any issues. I have since downloaded MBAM, which has found 6 instances of dnschanger trojans. However, no matter how many times I delete these reg keys they show up right after reboot.

After fighting with the adware for quite a while I finally gave in and reloaded the machine using the factory recovery disks figuring that a fresh install would be the answer to all of my problems. I was wrong. After the install, I reinstalled MBAM and found (I think) the same 6 instances of the dnschanger trojans. Still can't update Windows (now am running Vista pre-SP1) and can't download AVG.

I am now thinking that perhaps the adware has infected the external HDD that is connected to the machine, and the fresh install was negated. With no other place to back up the data that I have on this machine I am in search of some help with this issue.

Could it really be an infection in the external, or could the infected files have survived the install? Could there be other infections that the A/V programs have not found causing the dnschanger trojans to stick around?

Could really use some help on this one.

You have a HJT log posted 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 HJT 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 HJT 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 HJT 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 HJT 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 HJT Team member is already assisting you and not open the thread to respond.

If after 5 days you still have received no response, then post a link to your HJT log in the thread titled "Haven't Had A Reply In Five Days?".

To avoid confusion, I am closing this topic
