BleepingComputer.com: Combofix

Hi
This is my first time using this site.

I was fixing a virus on a computer a few days back which i could not access the internet on.
so i downloaded the latest version Combofix from bleepingcomputer.com as i always did in the past
saved it on a flash drive, transferred it to the infected computer, and it would not run.
The combofix icon had gone away - i tried a few different download sites, all with the same results.

Just to make sure i tried running it on a non infected computer - same result.
I tried a different flash drive to an infected and non infected computer - same result.

Can anybody help me please. i am baffled i have always been doing it this way,
it has always worked, combofix has always done a great job. What could be the answer??

Thanks Gabss

There are only two sites that are official and authorized combofix download sites.

The two sites are listed in the very last quotebox at the link hamluis posted above.

You may be having larger issues than not being able to transfer combofix.

If your machine is infected, also be aware that using it 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.

Further, when issues arise due to complex malware infections, possible false detections, problems running ComboFix (i.e. stalling, hanging, crashing) 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.

If you need assistance with a malware infection that requires using ComboFix, please read the "Preparation Guide For 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.
