Referred from here: http://www.bleepingcomputer.com/forums/topic351314.html ~ OB

I've been told to run dds and gmer and post the log files here but i can't get either of them to run. infact i can't get anything to run from task manager.

When i boot up the laptop all i get is a blank desktop screen with my wallpaper and a message "The ordinal 650 cold not be located in the dynamic link library ietutil.dll"

if i click ok or try and close the message it just reappears. If i Ctrl + Alt + Del i can sometimes get into task manager where there are 100's or processes running most of which end in SrvSrvSrvSrvSrv.... the more i try and do in task manager the more of these processes start up and once i get much over a 1000 processes the laptop gets very slow then stops responding and i have to restart it by holding down the on/off switch.

The problem started when i upgraded to a newer version of internet explorer as i was told to by a Microsoft security update as there were know security issues with the version i was using. once updated i was told to restart and i came up with a box telling me my ietutil.dd file was missing and i should insert my windows xp cd to repair it, which i did then i told me to reboot again and now i just get the ordinal 650 missing message as above.

Any ideas on how to find out whats going on and how to fix it.

Hello, Jbenny2.

I'm afraid I have very bad news.

Win32/Ramnit.A is a file infector with IRCBot functionality which infects .exe, and .HTML/HTM files, and opens a back door that compromises your computer. Using this backdoor, a remote attacker can access and instruct the infected computer to download and execute more malicious files. The infected .HTML or .HTM files may be detected as Virus:VBS/Ramnit.A. Win32/Ramnit.A!dll is a related file infector often seen with this infection. It too has IRCBot functionality which infects .exe, .dll and .HTML/HTM files and opens a back door that compromises your computer. This component is injected into the default web browser by Worm:Win32/Ramnit.A which is dropped by a Ramnit infected executable file.

-- Note: As with most malware infections, the threat name may be different depending on the anti-virus or anti-malware program which detected it. Each security vendor uses their own naming conventions to identify various types of malware.
With this particular infection the safest solution and only sure way to remove it effectively is to reformat and reinstall the OS.

Why? The malware injects code in legitimate files similar to the Virut virus and in many cases the infected files (which could number in the thousands) cannot be disinfected properly by your anti-virus. When disinfection is attempted, the files often become corrupted and the system may become unstable or irreparable. The longer Ramnit.A remains on a computer, the more files it infects and corrupts so the degree of infection can vary.

Ramnit is commonly spread via a flash drive (usb, pen, thumb, jump) infection where it copies Worm:Win32/Ramnit.A with a random file name. The infection is often contracted by visiting remote, crack and keygen sites. These type of sites are infested with a smörgåsbord of malware and a major source of system infection.

In my opinion, Ramnit.A is not effectively disinfectable, so your best option is to perform a full reformat as there is no guarantee this infection can be completely removed. In most instances it may have caused so much damage to your system files that it cannot be completely cleaned or repaired. Further, your machine has likely been compromised by the backdoor Trojan and there is no way to be sure the computer can ever be trusted again. It is dangerous and incorrect to assume the computer is secure even if your anti-virus reports that the malware appears to have been removed.

Many experts in the security community believe that once infected with this type of malware, the best course of action is to wipe the drive clean, reformat and reinstall the OS. Please read:

Whenever a system has been compromised by a backdoor payload, it is impossible to know if or how much the backdoor has been used to affect your system...There are only a few ways to return a compromised system to a confident security configuration. These include:
• Reimaging the system
• Restoring the entire system using a full system backup from before the backdoor infection
• Reformatting and reinstalling the system

Backdoors and What They Mean to You

This is what Jesper M. Johansson at Microsoft TechNet has to say: Help: I Got Hacked. Now What Do I Do?.

The only way to clean a compromised system is to flatten and rebuild. That’s right. If you have a system that has been completely compromised, the only thing you can do is to flatten the system (reformat the system disk) and rebuild it from scratch (reinstall Windows and your applications).


Here's a good article on how to reformat:
When Should I Format, How Should I Reinstall

Also, to protect yourself against malware and reduce your chance of reinfection in the future, I strongly recommend to have a look at following links (giving some advice and tips):
There are ways to clean it, but no guarantees. It sounds like it's quite advanced on your system. Please reply to this and let me know if you want to clean or reformat.
