Hello karen27 and welcome to TSF,

Please print out or copy this page to Notepad since you will not have any of browsers open while you are fixing this. Make sure to work through the fixes in the exact order it is mentioned below. If there's anything that you don't understand, ask your question(s) before proceeding with the fixes. Again, you should not have any open browsers when you are following the procedures below.

Go to My Computer->Tools/View->Folder Options->View tab and make sure that 'Show hidden files and folders' (or 'Show all files') is enabled. Also make sure that 'Display the contents of system folders' is checked. If you have Windows XP, the search feature is a little different. When you click on 'All files and folders' on the left pane, click on the 'More advanced options' at the bottom. Make sure that 'Search system folders', 'Search hidden files and folders', and 'Search subfolders' are checked.

Download CleanUp! (Alternate Link if main link doesn't work) and install it. Do not run it yet.

Restart your computer and boot into Safe Mode by hitting the F8 key repeatedly until a menu shows up (and choose Safe Mode from the list). In some systems, this may be the F5 key, so try that if F8 doesn't work. Make sure to close any open browsers.

Go to Start->Run and type in services.msc and hit OK. Then look for netinfo and double click on it. Click on the Stop button and under Startup type, choose Disabled.

Open HijackThis>Config>Delete an NT Service Copy/Paste the following into the box and click OK:

netinfo

Run a scan in HijackThis. Check each of the following and hit 'Fix checked' (after checking them) if they still exist (make sure not to miss any):

O23 - Service: netinfo - Unknown owner - C:\WINDOWS\netinfo.exe

Delete the following file if it still exists:

C:\WINDOWS\netinfo.exe

Open Cleanup! by double-clicking the icon on your desktop (or from the Start > All Programs menu). Set the program up as follows:
*Click "Options..."
*Move the arrow down to "Custom CleanUp!"
*Put a check next to the following:
-Empty Recycle Bins
-Temporary Internet Files
-Delete Cookies
-Delete Prefetch files
[color=Blue]-[X]Scan local drives for temporary files [/color] (Please uncheck this option)
-Cleanup! All Users
Click OK
Press the CleanUp! button to start the program. Reboot/logoff when prompted.

From Normal Mode:

Perform an online scan with Internet Explorer with Panda ActiveScan - requires Internet Explorer
  1. Click on the Scan your PC button & a 'pop up' window shall appear. * ensure that your pop up blocker doesn't block it
  2. Click On 'Scan Now'

  4. Begin the scan by selecting My Computer
    * You needn't remain online while it's doing the scan but you have to re-connect after it has finished to see the report.
  5. If it finds any malware, it will offer you a report. Click on see report
  6. Then click Save report
