    Tried several attempts to eradicate using Symantec but it keeps popping up in my temp files whenever I do malware scan or even a simple disk cleanup. I followed the cleanup procedure and have attached the logs. Thanks for your help.

    First you must disable Spybot's Teatimer as requested in the READ & RUN ME. See this: How to disable Spybot's TeaTimer

    Do you know what the below folder is for?
    Code:

    Run this [URL="http://www.majorgeeks.com/DisableRemove_Windows_Messenger_d2327.html"][B][COLOR=blue]Disable/Remove Windows Messenger[/COLOR][/B][/URL] to remove Windows Messenger. Do not confuse Windows Messenger with MSN Messenger because they are not the same. Windows Messenger is a frequent cause of popups.

    No idea what that program is. Attached logs as requested. Everything appears to be running fine but it appeared to be running okay prior with the exception of BrisvA which would go away. Let me know if there is more that I need to do. Thanks for your assistance.

    Ran another scan today it appears that BrisvA is still with me. What's next?

    Delete the below file:
    c:\program files\temp01


    Also delete the below folder:
    c:\program files\nkbcvs

    Attach a log from Symantec that shows exactly what and where this is being detected. If it is in System Volume Information then it is just System Restore.

    Attached is part the latest scan from Symantecs. Not sure if it is moving or creating temp files but it will cause the scan to go on for hours.

    I'm not sure whether this is valid or not. According to Symantec's own website, this infection is found in media files. They don't say anything about temp files. Have you been playing and form of multimedia type files (videos of any form or music)? If so stop for a few days and see if any detections still occur.

    Also run Symantec's specialty tool following their instructions. Be sure to disable System Restore as requested.

    Does that help?
