I do not know how I got this but since I got it, it uninstalled my zonealarm firewall and avast antivirus.

I cannot go into safe mode because it reboots continuously. Cannot run hijackthis because it says it is not a win32 compatible application.

Programs like malwarebytes, superantispyware, autoruns will hang after 30 seconds and bomb out.

I managed to run process explorer and killed the winupgro process but I am still not able to run programs to clean the infection.

If i try to install avg , the installation fails and cannot start the avg service.

I discovered that this spyware creates a hidden drivers folder under the user profile with wwinupgro, srosa.sys etc. I managed to delete this but it comes back.

Cleaned manually from recycler, prefetcher folders and dll cache, but to no avail. Even loaded the current user hive with the disk attached to another system and cleaned the load statement in hkcu\software\microsoft\windows\currentversion\run .

I believe there must be multiple copies of this with other names disseminated into the disk.

I do know at this stage if it has copied itself to the mbr. I tried bart pe but I am yet to work out how to install malwarebytes plugin.

Anyone please HELP! I can always reformat and re-install but I would prefer to remove this manually.

Thanks and regards

Try the following scan. You can copy it over from another computer if you need to. If you cannot boot into Safe Mode try running the scan in Normal Mode.

Before we start fixing anything you should print out these instructions or copy them to a NotePad file so they will be accessible. Some steps will require you to disconnect from the Internet or use Safe Mode and you will not have access to this page.

Please download DrWeb-CureIt and save it to your desktop. DO NOT perform a scan yet.

Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with Dr.Web CureIt as follows:
  • Double-click on launch.exe to open the program and click Start. (There is no need to update if you just downloaded the most current version
  • Read the Virus check by DrWeb scanner prompt and click Ok where asked to Start scan now? Allow the setup.exe to load if asked by any of your security programs.
  • The Express scan will automatically begin.
    (This is a short scan of files currently running in memory, boot sectors, and targeted folders).
  • If prompted to dowload the Full version Free Trial, ignore and click the X to close the window.
  • If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All.
  • When complete, click Select All, then choose Cure > Move incurable.
    (This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
  • Now put a check next to Complete scan to scan all local disks and removable media.
  • In the top menu, click Settings > Change settings, and UNcheck "Heuristic analysis" under the "Scanning" tab, then click Ok.
  • Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
  • When the scan is complete, a message will be displayed at the bottom indicating if any viruses were found.
  • Click "Yes to all" if asked to cure or move the file(s) and select "Move incurable".
  • In the top menu, click file and choose save report list.
  • Save the DrWeb.csv report to your desktop.
  • Exit Dr.Web Cureit when done.
  • Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
  • After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)

The power of accurate observation is commonly called cynicism by those who haven't got it.
