Hi,

I have a Dell Latitude with windows XP. Roughly a week ago it stopped working properly. The internet will connect but has no signal, even when I'm directly next to the router. All other computers on the network connect fine. Itunes and various other programs aren't working correctly either. I've run MalwareBytes and Rkill and come up empty. From my own experience I'm almost certain that there's a virus of some sort. Any help would be greatly appreciated.

Please download GMER from one of the following locations and save it to your desktop:
  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.

  • GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.
-- If you encounter any problems, try running GMER in safe mode.
-- If GMER crashes or keeps resulting in a BSODs, uncheck Devices on the right side before scanning

Ran it. Can't get past the password screen if I'm not in safe mode. Just shows my wallpaper with no icons or anything else to speak of. Any other ideas? :huh: :huh:

In Safe Mode go Start, then to Run, and type in "SFC.EXE /SCANNOW"

Right click on the C drive in Explorer and go Properties > Tools > Check Now (under Error Checking). Check both boxes then click "Start Now". A message will pop up saying that Error Checking will run after you restart the computer. Restart the computer and Error Checking will run automatically after the restart. After itís finished it will restart into Windows automatically.
