The Bho.cvx Trojan can be difficult to remove because it is protected by a driver which loads much earlier than actions taken to delete it. Further, the Trojan is often accompanied by other .dll files which need to be identified and removed. Successful removal also requires identification of the CLSID (unique id number) associated with the BHO and use of specialized fix tools. Before that can be done you will need you to create and post a hijackthis log.

Please read the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log". In step #9 there are instructions for downloading HijackThis and creating a log. (This is a self-extracting version which will automatically install the current version of HJT in the proper location.) If using Windows Vista, be sure to Run As Administrator.

When you have done that, post your log in the HijackThis Logs and Malware Removal forum, NOT here, for assistance by the HJT Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the HJT Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.

Start a new topic, give it a relevant title and post your log along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. Please include the top portion of the HijackThis log that lists version information. An expert will analyze your log and reply with instructions advising you what to fix. After doing this, we would appreciate if you post a link to your log back here so we know that your getting help from the HJT Team.

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 "bump" your post or 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.

Hi- I am still awaiting assistance for posting after receiving your instructions- http://www.bleepingcomputer.com/forums/t/128828/trojan-horse-bho-in-win32/

Does it normally take this long for a response or have I missed a step?

Thank you!

Hello deeteeassist,

Please be patient. It may take a while to get a response because the HJT Team members are very busy working on logs posted before yours. They are volunteers who will help you out as soon as possible.

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?".

Now that you have an open HJT log posted in the HijackThis Logs and Malware Removal forum, you shouldn't make any changes to your system.
Doing so, could change the results of the posted log, making it difficult to properly clean your system.

At this point, the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

I'm closing this topic until you are cleared by the HJT Team.
If you have any questions, don't hesitate to send me a PM.
Chaos reigns within.
Reflect, repent, and reboot.
Order shall return.

aaaaaaaa a~Suzie Wagner
