Hello,would you please do this first.

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • Make sure you are connected to the Internet.
  • Double-click on Download_mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
  • MBAM will automatically start and you will be asked to update the program before performing a scan. If an update is found, the program will automatically update itself. Press the OK button to close that box and continue. If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install.
  • On the Scanner tab:
    • Make sure the "Perform Quick Scan" option is selected.
    • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
  • Back at the main Scanner screen, click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad and you may be prompted to restart your computer. (see Note below)
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you will be presented with 1 of 2 prompts. Click OK to either and let MBAM proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot will prevent MBAM from removing all the malware.

Bitdefender has just popped up with the warning again about the trojan but has given this as the file infected C:\SystemVol......A0003485.exe. Thought i'd post to see if this info helps

The infected RP***\A00*****.exe file(s) identified by your scan are in the System Volume Information Folder (SVI) which is a part of System Restore. This is the feature that allows you to set points in time to roll back your computer to a clean working state. The SVI folder is protected by permissions that only allow the system to have access and is hidden by default unless you have reconfigured Windows to show it.

System Restore will back up the good as well as the bad files so when malware is present on the system it gets included in any restore points as an A00***** file. When you scan your system with anti-virus or anti-malware tools, they may detect and place these files in quarantine. When a security program quarantines a file, that file is essentially disabled and prevented from causing any harm to your system. The quarantined file is safely held there and no longer a threat. Thereafter, you can then delete it at any time.

Following the instructions to Create a New Restore Point and purge all but the most recent restore point with Disk Cleanup should also remove the infected files.

As for uninstall.exe, did you do a physical search of your system to locate that file? You can use Windows Search feature > More advanced options to see if the file(s) are still present. To do this, go to Start -> Search and click For Files or Folders... or just press the Windows key + F key on the keyboard.
  • Click All files and folders.
  • Type in the name of the file under "Search by...criteria."
  • Click More advanced options and check these options:
    • "Search system folders"
    • "Search hidden files and folders"
    • "Search subfolders"
  • Then click "Search" to look for the file(s).
If it exists, get a second opinion.

Go to jotti's virusscan or virustotal.com. In the "File to upload & scan" box, browse to the location of the suspicious file(s) and submit (upload) it for scanning/analysis.
-- Then post back with the results of the file analysis.
