OK, here is my situation. I have a HP/Compaq notebook that is infected by W32/Scribble-A (identified by SpySweeper, aka Virus.Win32.Virut.ce identified by Kaspersky). I have run a ton of tools on this machine and have cleaned/removed/disinfected over 3,000 files. After each scan, the machine instantly becomes reinfected. I have read that this virus is able to remain even after a format and reinstall of XP. I read that it can reside in RAM even when the machine is off, you would need to format, unplug, remove RAM and wait a bit then reinstall them and reload XP. Is that true?? Here is what I have done so far.... btw I am running XP Pro with SP3.

- Disable System Restore
- ATF Cleaner
- Ccleaner
- Easy Cleaner
- Malwarebytes
- Superantispyware
- Smitfraudfix
- Combofix
- SDfix
- F-Secure Blacklight
- Spybot 1.62
- Adaware AE
- a2Free
- Webroot Spysweeper
- Spyware Terminator
- Kaspersky Internet Security 2009

I am currently trying a recommendation from another site to try Dr. Web CureIT!; currently scanning and so far has "cured" 54, but we will see if that is going to be true, or if it will come back.....

Everything was fully updated, some run in safemode (as needed). I have used FileAssasin to remove a couple persistant files that could not be removed any other way.

I need some suggestions/help in trying to get this infection undercontrol without a complete reload of XP. Any help or suggestions will be greatly appreciated.

My take on this malware...
One or more of the identified infections is a backdoor trojan.

This allows hackers to remotely control your computer, steal critical system information and download and execute files.

I would counsel you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

Though the trojan has been identified and can be killed, because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of trojan, the best course of action would be a reformat and reinstall of the OS. Please read these for more information:

We can still clean this machine but I can't guarantee that it will be 100% secure afterwards. Let me know what you decide to do.

If you decide to clean

We need to run HJT.

Let me know it it went OK !

If you decide to Format

Not an unwise decision to make. In some instances an infection may have caused so much damage to your system that it cannot be completely cleaned or repaired. Wiping your drive, reformatting, and performing a clean install of the OS or doing a factory restore removes everything and is the safest action but I cannot make that decision for you.

Reformatting a hard disk deletes all data. If you decide to reformat, you can back up all your important documents, data files and photos. The safest practice is not to backup any autorun.ini or .exe files because they may be infected. Some types of malware may disguise itself by adding and hiding its extension to the existing extension of files so be sure you take a close look at the full name. After reformatting, as a precaution, make sure you scan these files with your anti-virus prior to copying them back to your hard drive.

The best proceedure is a low level format. This completely wipes the drive. Then reinstall the OS.
Use the free version of Active@ KillDisk.

Of course also feel free to ask anything on this in the XP forum. They'd be glad to help.

Well it looks like I was able to get it fixed. I had to use a couple extra tools to get the job done right though.... Dr. Web CureIt! is an invaluable tool!! It was able to find 50+ more infected files and was able to cure them. Then I used Remove 4 Pro SE. This was able to find and cure 20+ more. Last resort I downloaded and made a Dr. Web Live CD. I booted from this disc and nabbed one more. After that the computer started working almost perfect. I was able to get Kaspersky IS 2009 back and installed updated and did a full scan one last time, and all came up clean. I checked with a few more tools, and still all clear. I used the machine for some basic tasks and all worked well, internet worked flawless again, no hits on my firewall. At this point all is clean, all is done. This one is now done.
