win32: malware-gen cscript.exe

[J-man]

Avast keeps identifying cscript.exe as malware, even after it is moved to the chest.  I do not know whether cscript.exe is the legitimate file or a virus.

Running Windows XP version 2000 Service Pack 3

I have done a cleanmgr.  I have run several Avast scans, several MBAM scans, three ComboFix scans, and I have gone over the HijackThis log.  Infection was found in the System Restore so I turned that off and back on. Attached is the HijackThis log.  I also have the  two OTL logs, but they are too long to post.  I'd appreciate any help you can give me to get rid of this win32: malware-gen.  Thank you.

I do not know whether cscript.exe is the legitimate file or a virus.

Submit it to www.virustotal.com and check.

[Pondus]

I also have the  two OTL logs, but they are too long to post.

click on additional options and post the OTL logs as attachments

I read one of the other posts in the Avast forum that there was an update on Avast that would correct the false positive on cscript.exe.  I updated and ran another scan and cscript.exe was not tagged this time as a virus.

I am attaching the OTL logs but it may be unnecessary at this point.

[J-man]

I did one last scan with ComboFix and it questioned cscript.exe.  I did a SuperAntispyware scan and it came up with just a cookie which was removed.  I went to jotti and scanned the cscript.exe file:

Filename:  cscript.exe 
Status:  Scan finished. 2 out of 20 scanners reported malware.

File size:  135168 bytes 
Filetype:  PE32 executable for MS Windows (console) Intel 80386 32-bit 
MD5:  23d42c651f89420f7232aeb7a2a43d03 
SHA1:  8e34dbdc5fa9904ccd0d8f9acc462adbcf5ed474

I am going to consider this a closed case.  As far as I can see, this computer is clean.  This computer belongs to a pastor friend and I'm going to return it to him.  Thank you for your help.

I don't know how to post so I'm using this reply.  Perhaps someone can re-direct me.

My computer has been infected with Win32 Malware-gen.  I need help with this.  Don't know what it is, what it does, or how it may affect my laptop.  I ran Avast scan and it was recommended to quarrantine it.  What does this mean.  Do I have a serious problem and what can I do to prevent it from happening again?  Thanks - Chuck
