    We have 2 laptops (currently away from the office) that seem to be infected with something. We have scanned them with the currently installed Trend Corporate antivirus and Bitdefender. They both scan clean.

    Symptoms

    IE7 has a proxy server installed that can't be changed. Proxy Address is "^" and port is set to 80.

    Unable to connect to internet with IE7

    Unable to connect to local small business server - indicates server is unavailable.

    Domain administrator and Local machine administrator have been changed from Administrator user to Debug user and can't be changed back.

    Any ideas on what to try next to identify what is affecting these laptops when they are returned to the office?

    Sorry to be so vague, I'll have more details when the machines return.

    First note that these may not be malware problems.

    What do you mean installed? Do just mean that you have one configured in Internet Options, Connections, LAN settings, Proxy server? If so, are you saying you don't use a proxy? What happens when you uncheck Use a proxy server.

    If you have a proxy configured and don't need one, you will not be able to connect.

    Same problem as above.

    Is this a Server? Which OS are you using? This really does not sound like malware. Were ALL user accounts on this PC password protected.

    Have you tried using safe mode to resolve your problems?

    In order to determine if you have malware (and right now I not sure you do), I need you to run thru the below as best as you can and attach the requested logs.

    Please follow our standard cleaning procedures which are necessary for us to provide you support. Also there are steps included for installing, renaming, running, and posting HijackThis logs as attachments.
    • Run ALL the steps in this Sticky thread READ & RUN ME FIRST Before Asking for Support
    • Make sure you check version numbers and get all updates.
    • Very Important: Make sure you tell us the results from running the tutorial...was anything found? Were you unable to complete any of the scans?...Were you unable to download any of the tools?...Did you do the on-line scans as suggested? etc.
    • After doing ALL of the above you still have a problem make sure you have booted to normal mode and run the steps in the below link to properly use HijackThis and attach a log:
    Make sure you also rename HijackThis.exe as suggested in the procedures. Use analyse.exe for the new name. This is very important due to some new infections going around.
    • When you return to make your next post, make sure you attach the following logs and that you have run these scans in the following order too:
      • CounterSpy - only for Windows XP, 2K, & NT users
      • AVG Antispyware log - ONLY IF NEEDED you were not able to run CounterSpy. - only for Windows XP, 2K, & NT users
      • Bitdefender - from step 6
      • Panda Scan - from step 6
      • runkeys.txt - the log from GetRunKey.bat
      • newfiles.txt - the log from ShowNew.bat
      • HijackThis
    NOTE: You can only attach 3 files in a single message so it will require that you use two messages to attach all of these logs!
