    My son has a laptop that was continually generating pop-ups that said :security alert.It lasted for 6 hrs yesterday and after downloading the Microsoft updates, the popups went away. After I uninstalled Norton antivirus and added Kaspersky. It says system is clean now but we cant access internt.
    Any thoughts?

    Hi, jzim11 :)

    Welcome.

    Go to Start->Run->Type CMD and click Ok. The MSDOS Window will be displayed. At the command prompt, type the following and press Enter after each line:


    netsh int ip reset C:\Resetlog.txt
    netsh winsock reset catalog
    ipconfig /flushdns
    (The space between g and / is needed)
    Exit

    Restart the computer.

    If you are not able to connect after this, the following applications can be downloaded in a working computer and transferred to the troubled computer y means of a flash drive.

    Download OTL to your Desktop
    • Double click on the icon to run it. Make sure all other windows are closed and to let it run uninterrupted.
    • OTL should now start. Change the following settings
      • Change Drivers to All
      • Change Standard Registry to All
      • Under File Scans, change File age to 30
    • Under the Custom Scan box paste this in

      netsvcs
      msconfig
      safebootminimal
      safebootnetwork
      %SYSTEMDRIVE%\*.*
      /md5start
      eventlog.dll
      scecli.dll
      netlogon.dll
      cngaudit.dll
      sceclt.dll
      ntelogon.dll
      logevent.dll
      iaStor.sys
      nvstor.sys
      atapi.sys
      IdeChnDr.sys
      viasraid.sys
      AGP440.sys
      vaxscsi.sys
      nvatabus.sys
      viamraid.sys
      nvata.sys
      nvgts.sys
      iastorv.sys
      ViPrt.sys
      eNetHook.dll
      ahcix86.sys
      KR10N.sys
      nvstor32.sys
      ahcix86s.sys
      nvrd32.sys
      /md5stop
      %systemroot%\*. /mp /s
      CREATERESTOREPOINT
      %systemroot%\System32\config\*.sav
      %systemroot%\system32\*.dll /lockedfiles
      %systemroot%\Tasks\*.job /lockedfiles

    • Click the Run Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.
      • When the scan completes, it will open two notepad windows. OTL.Txt and Extras.Txt (first run only). These are saved in the same location as OTL.
      • Please post the contents of these files in your next reply.

    Download the GMER Rootkit Scanner. Unzip it to your Desktop.

    Before scanning, make sure all other running programs are closed and no other actions like a scheduled antivirus scan will occur while the scan is being performed. Do not use your computer for anything else during the scan.
    • Double click GMER.exe.
      [​IMG]
    • If it gives you a warning about rootkit activity and asks if you want to run a full scan...click on NO, then use the following settings for a more complete scan..
    • In the right panel, you will see several boxes that have been checked. Ensure the following are UNCHECKED ...
      • IAT/EAT
      • Drives/Partition other than Systemdrive (typically C:\)
      • Show All (don't miss this one)
        [​IMG]
        Click the image to enlarge it
    • Then click the Scan button & wait for it to finish.
    • Once done click on the [Save..] button, and in the File name area, type in "ark.txt"
    • Save the log where you can easily find it, such as your desktop.
    **Caution**
    Rootkit scans often produce false positives. Do NOT take any action on any "<--- ROOKIT" entries

    Please copy and paste the report into your Post.
