1st off I want to clarify that I have 23 years of experience working with computers in all aspects. I am very knowledgeable in virus and hijack removal but I have run into a situation that I am almost ready to give up on.

Have a Generic Desktop with Windows XP Pro installed that came in all infected with Alureon and a few other viruses. Standard procedure would be to boot in safe mode and try to run Combofix. I have found that in some cases this does not work so I will then take the drive out of the system and hook it to another and run MSE to make sure that it does have Alureon or some other rootkit issue, then I will rebuild the MBR and go from there.

I have a system that I have thrown everything and I do mean everything at and it claims to be all uninfected but I cannot run Rkill (any file) or Combofix on the system. Until I can get Combofix to run on the system then I will not be satisfied.

Rkill only comes up and says that it cannot find the .bat file. Combofix acts like it is going to run and then just shuts down with no messages or errors at all.

Also I found out something interesting when I was trying different things. When you type CMD in the run you do not get a command prompt. You have to type command to get the command prompt, also when you are in the command prompt you cannot run ANY commands, even the basic ones like dir ect. No errors, it just doesn't do anything.

I really would like to know what this is as I will probably run into it again beings that 70 % of what we do is virus removal.

Also please no comments like format the drive and re-install the operating system, we are not Bestbuy ect.....

Thanks for any and all help.

Welcome to BC dvdmizer

I understand your frustration but as a general policy, Bleeping Computer does not offer advice on how to run ComboFix unless we asked someone to run it or if there is a problem with the computer caused by running the tool. This is because people should not be using ComboFix without being advised to do so by a trained expert (i.e. Malware Response Team) who is assisting a member deal a malware issue on that system. When issues arise due to complex malware infections, possible false detections, problems running ComboFix or with other security tools causing conflicts, experts are usually aware of them and can advise what should or should not be done while providing individual assistance. When false detections are identified, experts have access to the developer and can report them so he can investigate, confirm and make corrections. Those attempting to use ComboFix on their own do not have such information and are at risk when running the tool in an unsupervised environment.

Further, using ComboFix is only one part of the disinfection process. Preliminary scans from other tools like DDS, RSIT and GMER should be used first because they provide comprehensive logs with specific details about files, folders and registry keys which may have been modified by malware infection. Analysis of those logs allows planning an strategy for effective disinfection and a determination if using ComboFix is necessary. Please read the pinned topic ComboFix usage, Questions, Help? - Look here.

With that said we are certainly willing to help with the infection so if you need assistance, please read the "Preparation Guide For Use Before Using Malware Removal Tools and Requesting Help".
  • If you cannot complete a step, then skip it and continue with the next.
  • In Step 7 there are instructions for downloading and running DDS which will create a Pseudo HJT Report as part of its log.
  • When you have done that, post your log in the Virus, Trojan, Spyware, and Malware Removal Logs forum, NOT here, for assistance by the Malware Response Team Experts.
