hello,

recently, I picked up some spyware which really messed up my computer. First it stopped me connecting to the internet on my desktop pc which is running windows xp home, (but my wireless connection was fine, hence I'm still using my laptop) kept trying to connect to dodgy sites, disabled my task manager, stopped me opening any progams and gave me false popups about buying virus protection (a program called antivirus soft)

Eventually I managed to start my task manager before the virus kicked in right when I started up my computer, and all my problems actually disappeared apart from the internet not working. I have found 4 spyware registrys using my virus software, which are all hiding in C:\system volume information\_restore.... *and then a whole load of numbers*. Example -

C:\system volume information\_restore{B1AF6306-70F0-4416-91D0-2A49F3B95B86}RP1618\A0363891.exe

there are 3 other variations of this. 3 are identified as FraudTool.Win32.XPSecurityCenter.P and the other as FraudTool.Win32.XPSecurityCenter.u

My virus software (Virgin Media Pc Guard) has just left it where it is.

So do I just delete the files? Do I actually need them, is the whole file the virus, or is it a genuine windows files which contains the virues and thus I need to go into it and delete parts of it?

I've read that if you turn off system restore and then do something it will fix the problem, but I'm not sure. Any help would be appreciated.

Thanks.

Hello we will get them last. Don't turn off . Better to to have an infected restore point then none if needed till we are done.
Run one more scan first please.

Run TFC by OT
Please download TFC by Old Timer and save it to your desktop.
alternate download link
Save any unsaved work. TFC will close ALL open programs including your browser!
Double-click on TFC.exe to run it. If you are using Vista, right-click on the file and choose Run As Administrator.
Click the Start button to begin the cleaning process and let it run uninterrupted to completion.
Important! If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway to ensure a complete clean.

Next run MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware (v1.46) 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.

The detected _restore{GUID}\RP***\A00*****.xxx file(s) identified by your scan were 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 monitoring a core set of system and application files and by creating backups (snapshots saved as restore points) of vital system configurations and files before changes are made. 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. See What's Restored when using System Restore and What's Not.

System Restore is enabled by default and will back up the good as well as malevolent files, so when malware is present on the system it gets included in restore points as an A00***** file. If you only get a detection on a file in the SVI folder, that means the original file was on your system in another location at some point and probably has been removed. However, when you scan your system with anti-virus or anti-malware tools, you may receive an alert that a malicious file was detected in the SVI folder (in System Restore points) and moved into 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 delete it at any time.

If your anti-virus or anti-malware tool cannot move the files to quarantine, they sometimes can reinfect your system if you accidentally use an old restore point.

Since you are still having issues, follow boopme's instructions. When the system is fully cleaned he will provide instructions to ensure those restore points are properly removed.
