Have just been targetted by spyware program called Medichi.exe.

Started by clicking on an image on the web and my system instantly shut down and rebooted. I did not have the foresite to get it into safe mode when it rebooted either. As soon as the computer was back up and running files started to be copied over the internet connection and I was told that I had spyware on my machine and I needed to download some advertised spyware repair software to sort the problem out. Having realised it had knocked out Norton I did manage to download Spydoctor which detected the Medichi.exe and Medichi2.exe files, but having deleted these they reappeared on the next reboot.

In terms of the effect on the laptop... I could no longer run Norton, The control panel was non-accessable, I couldn't change the time/date and when I did it said there were restrictions in place and I should contact the system administrator!
I did have a go at starting in safe mode to do a system retore, but this to had been affected and I could only do a system restore at dates after the infection!

I am fully prepared to "flatten" the C drive and start again, but I wondered if there is anything else at all I can try before I do this to clean the laptop up as tracking down all the installation disks will take a long while.

Reading previous posts I guess I should download HiJackThis and post the report. Will this help with the fix ort should I just cut my losses and re-format?

Any help will be greatly appreciated.

Great. I will give that a go immediately. What state will this get my laptop to. Will this fix as far as possible get my laptop back to the state it was in before the infection?

Many thanks for the thorough solution. I will let you know how it goes!

There are no shortcuts or guarantees when it comes to malware removal. Sometimes it takes several efforts with different tools to do the job. Even then, with newer types of malware infections, the task can be arduous. In some cases the malware infection may have caused so much damage to your system that it cannot be successfully cleaned and the only option is to reformat/reinstall the OS.

Just had a go at running through the list of fix programs in your guide and I seem to have fallen at the first hurdle. Although I can run other exe's on the system i cannot run SmitfraudFix.exe at all, either on the desktop or in the root directory.

I have even tried to run it in safe mode and downloaded it a second time to make sure that I had got a good download of the program, but nothing at all!

Any suggestions?

Are you getting any error messages when trying to run smitfraudfix? What exactly happens when you double-click on it?

If you cannot get it to run, just skip for now and proceed with the rest of the instructions.

I get absolutely nothing when I double click on it. No error messages, nothing. I can't even run it from the command window.

Ok. As I said, go with the rest of the instructions. In the cases I've seen so far, there is other malware present so I want to see what else your dealing with. We may need to use another tool on medichi.exe so let me know its location (full file path) on your system.

I have found a way to run some programs. Simply take that exe installer or "smitfraudfix.exe" and simply add a space to the name. Then give it a go immediately and most of the time it works (for me anyway).

Also submit Medichi.exe and Medichi2.exe to jotti's virusscan or virustotal.com. In the "File to upload & scan" box, browse to the location of the suspicious file and submit (upload) it for scanning/analysis.
Post back with the results of the file analysis.
