How to remove Firefox and Internet Explorer redirect virus

As this is my first attempt at writing a guide any feedback would be appreciated.

OK, as some of you know I am self employed as an IT consultant/technician. I cant count how many times per week I have to remove viruses off client computers that are very similar. This guide will take you step by step through removing the nasty little problem that hijacks your Firefox and Internet Explorer browsing.

Some other symptoms are: you cannot open Windows Updates webpage, you cannot open the Malware Bytes web page, or Superantispyware web page, and many other I imagine.

This virus is a file appears as a process in Task Manager named 'csrcs.exe' some of you may note it is very similar in name to 'csrss.exe' which is a process that is required by Windows to function.

I wont go into details of how you got infected, although it infected my machine through my USB stick conveniently. I was on my fiancees laptop at the time, needless to say, that conversation did not end in my favour.


First off, anything in quotations is typed text, do not actually type in the quotations unless specifically told.

Open up command prompt by typing in 'cmd' into the run dialogue box and clicking OK.

Typing in the following commands, after each line you need to press the enter key:

cd windows\system32
taskkill /im csrcs.exe
attrib -h -s -r +a csrcs.exe
del csrcs.exe

Now go to run again and type in 'regedit' and click OK.

Click Edit then Find. Make sure Keys, Values, and Data is ticked and Match whole string only is unticked. Type 'csrcs.exe' in the box and click search, delete all references to this file. Except one, you will find an entry in the following registry hive:

HKLM\Software\Microsoft\Windows NT\Current Version\Explorer\Winlogon

It will be a String value named 'Shell' with a value of 'Explorer.exe csrcs.exe'

DO NOT DELETE this value, Windows wont boot correctly if you do, you must change the value so it reads 'Explorer.exe'

After it has finished searching the registry your almost done.

You should be able to open Malware Bytes web page now, which is you can also download Malware Bytes from

After running a full scan, reboot and you should be OK to browse, if you still experience problems, start a thread describing your problem and send me a private message with a link and I will do my best to respond as soon as I can.

Now, I thought that this one was a variant of Spybot. Spybot includes a nice keylogger, as well as the ability to upload/download code and execute it...
