Virus, Trojan Removal?

Hello: I am here to find out how to remove lets say, the "Antivirus Live.exe"!
My brother just had this Virus we live in different states
No matter what you do to get rid of this virus, it does not work. First of all, all the advice for removal cannot be done because it simply takes over everything and even if you uncheck the Lan Proxy Server tip, it places the check right back in there.
And then instructions say to download Malwarebytes etc. even though my brother has all this stuff, if cannot be run or downloaded because of the re-directing this virus does.

Please dont mention any downloads, they are just not accessible.
Even the Registry is closed off and the Run command

Does any one know of a TRUE way to get rid of this kind of virus without formating the drive?

 

Ok, it windows xp Home (oem), the reason I said dont mention downloads is because he wasn't able to go to any sites other than Porn sites (redirected each time he tried)
The pc would not accept any CD's either.
You did give a great Idea when you said, take out the Harddrive and scan it on another pc, dont know if would work or not, but will keep it in mind next time
However, We solved the problem, here is what happened, I tried to get him to run Malwarebytes from his desktop icon and it would not run.
After hours of trying he figured out that the trojan had taken over his taskbar and thats why nothing worked from there.

So to get Malwarebytes to run we had to click on the Malwarebytes Icon from the Desktop BEFORE the taskbar came up and Malwarebytes ran Great and caught 9 infections 7 real 2 False positives.
Pc now runs good again.
Sorry if I sounded a little strong on my post but all I saw on fix's thru out the internet were fix's that were impossible to perform, they just dont get it, when a machine is taken over, its taken over

Im sure if it happened to you, you would understand exactly what I mean!

Anyway, Thank You Very Much for your instructional reply, it is really appreciated.

 

You said>>>
Actually, there is typically a work around and some of our tools almost always run even when various scan tools do not. And this allows us to get started. But obviously you have to get the tools onto the PC first.

I did not know you had these tools, but if nothing can be ran on the infected pc, how are your tools run, by Disk Offline?

 

Quote: Too many people quit before trying all steps and with out following instructions properly to try thing in safe boot mode, or safe boot mode with networking or from safe mode with command prompt as we request.

In addition, those other tools mentioned will run. You just have to make the CDs. <<<

Thats the point, Safe Mode dont work and CD's are not able to be played,

Alot of people are well aware of what you can do if these things worked?

 

No, he had no flash drive available, put will let him know to keep one handy!

Network connection was taken over via Lan proxy settings, but we just set a registry hack to lock the Lan settings from proxy's
IP address's could not be used either, No access to command prompt or run.

All attempts to run antivirus etc were stopped!

Ms config would not come up at all.

Believe me this virus was pretty complete, but as you said if Malwarebytes ran and the only reason it did was as mentioned he figured it out that the virus had control of the taskbar but not the desktop IF and Only IF he was able to click on something from the desktop BEFORE the taskbar came up.

What tools from MG can we keep handy and should they be on a disk or flash drive? Thanks
