My netbook running the Windows 7 Starter operating system appears to have been infected by a virus. Yesterday I was online when it started to bring up continuous messages asking I wanted to allow an unknown program to make changes to my computer. I kept clicking 'No' but the messages kept coming up. I managed to delete my temporary internet files, since I thought this was where the problem was coming from, and restarted my computer. When I logged on again, the desktop was completely black with no icons, and my Start menu was missing programs. The My Documents folder and all of my files had disappeared. System Restore appeared to have been disabled. I ran a MalwareBytes full scan which found nothing, since Microsoft Security Essentials appeared already to have removed a Trojan called Win32/FakeSysdef and a couple of other files.

So my computer now appears to be clear of the files causing the virus. I managed to unhide the missing files, but the desktop background is still black and my Start Menu is still completely different. I can't access folders such as My Pictures through Windows Explorer because 'access is denied'. Worse, although Security Essentials doesn't show anything in the scan and has removed everything that can be removed (another Win32/FakeSysdef appears to quarantined on the computer, though I can't remove it), it keeps detecting new potential threats. I can't work out if the virus has been removed and if my private information is still at risk, and my computer is still not back to how it was. I took it into a computer repair shop and was told that the only way to fix it was to spend a lot of money reinstalling Windows. Is there anything else I can do?

Your help is appreciated, and if you need any more information let me know.

Let's see, if we can recover your missing features.
Download and run UnHide
Let me know, if it worked.

=======================================================

Download Security Check from HERE, and save it to your Desktop.

* Double-click SecurityCheck.exe
* Follow the onscreen instructions inside of the black box.
* A Notepad document should open automatically called checkup.txt; please post the contents of that document.

=============================================================================

Please download MiniToolBox and run it.

Checkmark following boxes:
  • Report IE Proxy Settings
  • Report FF Proxy Settings
  • List content of Hosts
  • List IP configuration
  • List last 10 Event Viewer log
  • List Installed Programs
  • List Users, Partitions and Memory size
Click Go and post the result.

=============================================================================

Download Malwarebytes' Anti-Malware (aka MBAM): https://www.bleepingcomputer.com/download/malwarebytes-anti-malware/ to your desktop.

* Double-click mbam-setup.exe and follow the prompts to install the program.

=============================================================================

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.

IMPORTANT! If for some reason GMER refuses to run, try again.
If it still fails, try to UN-check "Devices" in right pane.
If still no joy, try to run it from Safe Mode.
