    Hi All

    This is my first time posting on this website. I'm having a unique issue with this Lenovo A70z All-in-one machine. Its a windows 7 32-bit sytem. A few weeks ago, one of the users reported that their machine stopped working. I checked and the internet icon had an exclamation mark on it. I tried few things but it didnt help. So I brought it to my office and started troubleshooting it.

    First thought was that it is a hardware failure so I tried Cisco USB 300 Usb to ethernet adapter, assigned it an IP (we only use static IP's) and tested it but it didn't help. Same exclamation mark. At this time, it was connected to a small trendnet switch where my personal laptop is also connected. So a trendnet switch where wall cable plugs into and then two cables connected to the switch (one my laptop and other is this Lenovo machine). I noticed that after few minutes my internet connection showed an exclamation mark. I disconnected the wall cable from the switch and plugged into my machine and my internet started working. I then ran all sorts of virus detectors, malwarebytes, TDSSkiller, Combofix and few other but nothing popped up.
    I then tried to connect the wall cable directly to affected machine and still the same issue with yellow exclamation mark. Sometimes I noticed that ethernet adapter manual settings had gateway address missing so I entered it again (even though I'm 100% that I entered it the first time).

    So long story short, I'm still having issues with the machine. I installed fresh windows 7 32-bit (deleted the system and C: partition and then recreated the partition), didn't touch the recovery partition and after fresh install, i'm still having the same issue. As an IT person, I'm interested to know what would cause the issue. Any help from you guys would be greatly appreciated. I also updated the nic drivers but that didnt help.

    Please help!!

    Hi Guys

    Ran all the scans as recommended. Attached 3 log files. TDSSkiller and Malwarebytes didnt find anything so I didn't attach anything.

    Please let me know if you need more info.

    Welcome to Major Geeks!

    You are not having malware problems. All the logs are clean. The only observation is that the Ethernet adapter shows as disconnected
    Code:
    Ethernet adapter Local Area Connection:
   Media State . . . . . . . . . . . : Media disconnected
   Connection-specific DNS Suffix  . : 
   Description . . . . . . . . . . . : Realtek RTL8168D/8111D Family PCI-E Gigabit Ethernet NIC (NDIS 6.20)
   DHCP Enabled. . . . . . . . . . . : Yes
   Autoconfiguration Enabled . . . . : Yes
    Sometimes this would be a driver issue or a software conflict, or simply a bad cable. Sine you have reinstalled from scratch I would rule out the first two. And I assume with all the testing, you would know the cable is good.


    Possibly broken hardware due to a power surge or some other failure. Sometimes this could impact other ports in a PC too. You would be better off trying to address this non-malware topic in the Hardware or possibly Networking Forums.

    Thanks Chaslang for replying!

    Is it possible to move this thread to Hardware/Networking section or do I need to repost my initial thread information again?

    Thanks for your help.

    It would be best if you reposted in the networking forum.

    If you are not having any other malware problems, it is time to do our final steps:
    1. We recommend you keep Malwarebytes Anti-Malware for scanning/removal of malware. You can uninstall RogueKiller and HitManPro.
    2. Go back to step 6 of the
      READ ME       and renable your Disk Emulation software with Defogger if you had disabled it.
    3. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
    4. If running Vista or Win 7, it is time to make sure you have reenabled UAC by double clicking on the
      C:\MGtools\enableUAC.reg file and allowing it to be added to the registry.
    5. Go to add/remove programs and uninstall HijackThis.
    6. Goto the C:\MGtools folder and find the MGclean.bat file. Double click on this file to run this cleanup program that will remove files and folders
      related to MGtools and some other items from our cleaning procedures.
    7. After doing the above, you should work thru the below link:
    Malware removal from a National Chain = $149
    Malware removal from MajorGeeks = $0
