I am dealing with the Fedex Virus. I followed http://www.techjaws.com/fedex-email-malicious-attachment/ instructions of:

1.Reboot your PC and hit F8 to run your computer in Safe Mode with Networking.
 2.Download MalwareBytes to your desktop and rename it to Explorer.exe as Windows Security 2011 blocks the program named MalwareBytes. If you can’t download files, try using another machine that’s not infected and saving the files to a flash drive or other storage device.
 3.Download and Run RKILL to stop all background processes related to Windows Security 2011.
 4.Launch MalwareBytes and run a (Full Scan) to remove infections.

Were completed.

However the next step does not work

5.Delete the file called “Hosts” in C:\Windows\System32\Drivers\etc\HOSTS and add the default Hosts file (below) for your operating system in C:\Windows\System32\Drivers\etc\

The existing host file was not modified. This is a new and improve Fedex redirect virus and uses a different method of redirection.

if I try housecall.trendmicro.com or similiar, I am redirected to www.google.com.  What method would the redirection be done?

I would use ComboFix to get rid of the problem:

Also. run TDSSKiller to check for rootkit infections which are common for redirecting issues.

How about trying a system restore. Restore your computer to a time when you know the computer was working fine, before you got the virus. Doing a system restore will not cause you to lose any new data or documents you have created it will just restore your computer to a time before the infection. A system restore may save a lot of time troubleshooting trying to remove the infection.

Obviously a system restore will not always work but it is worth a try.

Tried the system restore and could not complete it.
Ran Combofix It did find and I assume fix problem
Ran TDSSkiller and it found nothing.
Do not see the redirection problem. Will run the 10 days Microsoft scan.

If the sytem can not restore to an earlier time it probably indicates that the virus maybe preventing the system restore.  you can try to fix the windows issues by opening a dos window. Click the start button, click run, type cmd.... to get the dos prompt.

Then you want to type "sfc /scannow"  (do not type the quotation marks)
Running this command may or may not ask you to insert your windows disc.

I also believe the virus prevented the system restore.
Microsoft msert found 5 infected files. Currently running Eset.
I belive the Combofix took out most of the infection. I not seeing the redirection. Before I was redirected when trying to reach Trend Micro, Microsoft and Eset. However since things are still being found, I am still running malware finders.

Here is the combofix.txt which I believe is the log that was requested.
ComboFix.txt

It looks like Combofix did take care of the main files of the infection.

One suggestion, when you are done removing the infections, make sure to uninstall Combofix.

Do so by running the command 'Combofix.exe /uninstall' from an elevated command prompt.  This will clear out any extraneous files left behind by Combofix and delete the .exe itself.

Good job removing the infection ! :)

Eset found nothing. I assume that the problem is gone.

If I run as administrator and open a command prompt window, then run Combofix.exe, I get: C:\Windows\system32>combofix.exe /uninstall
'combofix.exe' is not recognized as an internal or external command,
operable program or batch file.

you have to be in the directory of the Combofix executable for the command to work.

I can not find combofix.exe by doing a search on the C drive. I do see the Qoobox folder but no executable.

Okay, if you just ran instead of saving Combofix, that can happen.  Just download Combofix again to a location you know.  Then run 'Combofix.exe /uninstall' from an elevated command prompt once in the proper location (i.e. C:\Users\(USER)\Desktop\>)

Yes, was running as administrator. However, I deleted combofix.exe. Downloaded combofix again and then was able to use the combofix.exe /uninstall.
