can not find script file

Steve's right, Panda will find it but depending on how you got it, Panda may not remove it all. Usually this worm propogates through removable media but you could also have gotten it from a malicious web site. Part of your problem (any of the spyware that came with it) would remain after the Panda scan.
Trend Micro has the complete cure if you want to give it a shot:

Download Sysclean Package & save it to your desktop.

• Create a new folder on drive "C:\" and rename it Sysclean - (C:\Sysclean).
• Place the sysclean.com inside that folder.
• Then download the latest Virus Pattern Files - (Pattern files are usually named lptxxx.zip, where xxx is the pattern file number)
• Extract the lptxxx.zip pattern file into the same folder you created for and placed sysclean.com. (Click here for information on how to extract a file if your not sure how to do this. DO NOT 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".
Note: Some anti-virus programs such as Avast will alert you to a virus attack when running sysclean so it's best to disable them before going to the next step.

Scan with Sysclean as follows:

• Open the Sysclean folder and double-click on sysclean.com to start the scanning process.
• Put a check mark on the "Automatically clean or delete infected files" option by clicking in the checkbox.
• Click the Advanced >> button.
• The scan options appear. Select the "Scan all local fixed drives".
• Click the "Scan button" on the Trend Micro System Cleaner console.
• It will take some time to complete. Be patient and let it clean whatever it finds.
• Another MS-DOS window appears containing the log file generated in the System Cleaner folder.
• To view the log, click the "View button" on the Trend Micro System Cleaner console. The Trend Micro Sysclean Package - Log window appears.
  • The Files Detected section shows the viruses that were detected by System Cleaner.
  • The Files Clean section shows the viruses that were cleaned.
  • The Clean Fail section shows the viruses that were not cleaned.
• Exit when done, reboot normally and re-enable your anti-virus program.

This tool generates a log file (sysclean.log) in the same folder where the scan is completed. When using Sysclean its best to use the Administrator's account or an account with Administrative rights otherwise you will not have the rights to scan some locations. The scanning process may result in "Access Denied" messages for some files. This is normal because these files are protected by the system.
