Hope someone can give me some 'simple' advise on how to rid my PC of this. Trend Micro yesterday picked up a ? Trojan - file WinSys2.exe and the message was that I had to decide whether it was a Trojan or not. Didn't have a clue so rang them. They decided it was and got me to remove it from C/system32. Next to it was a green little man icon named WinSys2 and they said to remove this also - but it wouldn't go so they have sent me a 'removal tool' with about 10 pages of complicated instructions which has given me a migraine just reading it let alone trying to work out what to do.
To-day another one has popped up [size="2"]Troj Gen 0X27125, file A0027665.exe. This one is unknown to Google and apparently is hiding in C/System Vol Information\ restore (which I can't find on my computer in C at all.)
Again, the message is that I have to decide whether it is a goodie or a baddie and as I haven't a clue I'm hoping some of you smart ones out there can tell me. if it is - how do I get rid of it. This is the 1st time in 8 years I am showing a trojan and twice in 2 days is two too many so HELP please!!!!

The detected _restore{GUID}\RP***\A00*****.xxx file(s) identified by your scan are in the System Volume Information Folder (SVI) which is a part of System Restore. The *** after RP represents a sequential number automatically assigned by the operating system. The ***** after A00 represents a sequential number where the original file was backed up and renamed except for its extension. To learn more about this, refer to:System Restore is the feature that protects your computer by creating backups (snapshots saved as restore points) of vital system configurations and files. These restore points can be used to "roll back" your computer to a clean working state in the event of a problem. This makes it possible to undo harmful changes to your system configurations including registry modifications made by software or malware by reverting the operating systems configuration to an earlier date. The SVI folder is protected by permissions that only allow the system to have access and is hidden by default on the root of every drive, partition or volume including most external drives, and some USB flash drives. For more detailed information, read System Restore Overview and How it works and How antivirus software and System Restore work together.

System Restore is enabled by default and will back up the good as well as malicious files, so when malware is present on the system it gets included in restore points as an A00***** file. When you scan your system with anti-virus or anti-malware tools, you may receive an alert or notification that a malicious file was detected in the SVI folder (System Restore points) but the anti-virus software was unable to remove it. Since the SVI folder is a protected directory, most anti-virus and scanning tools cannot access it to disinfect or delete these files. If not removed, they sometimes can reinfect your system if you accidentally use an old restore point.

To remove these file(s), the easiest thing to do is Create a New Restore Point to enable your computer to "roll-back" to a clean working state and use Disk Cleanup to remove all but the most recent restore point.
Vista Users can refer to these links: Create a New Restore Point and Disk Cleanup in Vista.

I also recommend you do the following:

Please download Malwarebytes Anti-Malware (v1.37) and save it to your desktop.
alternate download link 1
alternate download link 2

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on 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 definition 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.
  • 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. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.
