Operating system: Windows XP SP2
Internet Explorer 7.0.5730.11
McAfee Internet Security Suite 8
ISP: SBC Yahoo DSL


Problem: When I tried to connect to the internet using the Yahoo shortcut key, I received a McAfee message that the trojan “Generic Adclicker.d” had been detected, and my C:\Windows\browser.exe file was deleted to complete the clean process. I looked on the Yahoo installer CD to see if the file was there. Through Explorer, I found the file on the CD and clicked on it. I immediately got a McAfee box saying “the file D:\Setup\Browser.exe is infected by the Generic Adclicker.d trojan and cannot be cleaned”. I disabled the Virus Scan and copied the file from the CD to the hard drive. Upon enabling Virus Scan, it immediately deleted the file from my hard drive again. I tried to re-install the Yahoo software through the CD and it will not do so.

Questions:
1) How is it that the original browser.exe file on CD is being detected as being infected with the trojan?
2) What steps do I need to take to be able to copy and use the browser.exe file?

Thank you for any assistance you can provide.

Here is some info on this.

* An icon will be created on your desktop. Double-click that icon to launch the program.

* When done, select "Scan for Harmful Software".
* There are three scanning options. Choose "Perform Complete Scan" and click "Next".

If you still have the same symptons please read and follow all instructions in the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log". You may have performed some of these steps already. About half way down are instructions for downloading HijackThis and creating a log.

When you have done that, post a log in the HijackThis Logs and Analysis 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.

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 here.

After posting a log 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. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make may cause confusion for the member assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

In addition to malware, browser.exe seems to be a commonly named file used by other vendors like Earthlink and SlimBrowser.

Submit the file to jotti's virusscan or virustotal.com for another opinion. In the "File to upload & scan" box, browse to the location of that file and submit (upload) it for scanning/analysis.
Post back with the results of the file analysis.

If this file came from Yahoo and no other vendors are detecting it as bad, then you need to contact the Yahoo support techs and advise them what McAfee is detecting.
