wscript.exe in the startup of windows XP, 99% of the resources

Hi all,

curiosly since yesterday this process appears in the moment in which one of our computers is restarted. The process is wscript.exe and the consumption of this process is the 99% of the resources. This process blocks the computer completelly, specially in terms of the internet and outlook connections. All the applications are blocked.

I dont really know if it is a virus or not, i could read different things. The first is next fro microsoft:

wscript.exe file information. The process Microsoft (r) Windows Based Script Host belongs to the software Microsoft (r) Windows Script Host or wscript.exe by Microsoft Corporation (www.microsoft.com).
Description: File wscript.exe is located in the folder C:\Windows\System32. Known file sizes on Windows XP are 114688 bytes (68% of all occurrence), 118834 bytes, 151552 bytes.
The file is a trustworthy file from Microsoft. The program has no visible window. Therefore the technical security rating is 5% dangerous.

If wscript.exe is located in a subfolder of C:\Windows then the security rating is 16% dangerous. File size is 114688 bytes. The program is not visible. File wscript.exe is a trustworthy file from Microsoft. File wscript.exe is not a Windows core file.

and this another found in the Internet (http://www.auditmypc.com/process/wscript.asp):

Hard to say if its a virus or just a startup script thats running havoc.

wscript.exe per se is not a virus, its Microsofts VBScript engine.

If  the computer is a member in a domain, the script could have been started by a group policy.

Anyway, you should be able to cancel wscript.exe via task manager.
Then do a scan with t least 2 decent virus scanner.
Then check your startup config with AutoRuns (http://technet.microsoft.com/en-us/sysinternals/bb963902.aspx) and try to find the start of wscript.exe.

Hope it helps

yes, the computer is member of a domain, do you know how we could test this to be sure if it is a group policy?

Hi thyet,

It might be something like

wscript.exe "C:\folder\somescript.vbs"

The parameter is what you want to find out

Inspect the registry RUN keys:

Or use Autoruns tool to track the wscript.exe entry.

Thanks, I'll try it and i'll tell you.


Thanks all for your help, the problem finally was linked with one of the group policy.
