Backdoor trojan

Hi, sorry if i haven't put this in the right section, was going to put in off-topic but what the heck! :P

Here's the deal. There are three computers connected to the network via cable and occasionally a laptop is used wirelessly. My dad's computer, a three/four year old dell, still decent, (well, was lol) got a virus the other day, avast is saying its a 'backdoor trojan' and is recommending that i 'move to chest', i have tried both 'delete' and 'move to chest' and it doesnt perform any actions. There was also an amazing amount of spyware that fried my brain for hours before i finally got rid of most of it with AVG and Spybot S&D. System Restore won't respond at all on the computer.

I contacted symantec to get a price on virus removal and they quoted me £70, this is done via remote access. We are not prepared to pay that much. I contacted other local computer places and they said price varies on how long it'll take ( ie RIP-OFF merchants ).

I am now thinking about wiping the hard drive (formatting) and re-installing everything again. I've never done this before so i don't want things to go wrong. Can anyone maybe explain any alternatives to gettin rid of the virus cheaper or take me through wiping the hard disk - what i must ensure i do before wiping etc.

Thanks in advance! :worship: :worship: :worship:
 
Simplest thing, outside of downloading more tools, is to run u`r antivirus stuff in SafeMode.

Get into SafeMode by pressing F8 whilst u`r pc boots. Just after the motherboard information posting, and b4 the Windows thingy with the moving bar appears.

If that doesn`t solve the prob, we need to look further.
 
ok so i've ran the computer in safe mode and all i can see is a screen with 'safe mode' at each corner and in the top middle 'XP (Build 2600******: service pack2) so after i log in, explorer is not coming up.
 
I don't mean Internet explorer. I mean explorer - the whole start/icon interface. Nothing will start when i run safe mode on the computer and a prompt comes up saying to go to control panel - this is impossible as i cant even get into the main windows screen.

If i run the computer normally and go into control panel i can't see anything that says anything about safe mode :mad:

Is there anything else i can do?

What are your thoughts on just reformatthing the C drive? This will definently get rid of the trojan?
 
Does ctrl+alt+delete give you an option to start task manager. From there you could start explorer.exe manually and that should give you a taskbar and start menu.
 
Can you Ctrl + Alt + Del? To get the task manager?

Cos then you could start a new "explorer.exe" by clicking Applications and clicking new task.

Type explorer. Then press enter.

(sorry nrage) :)
 
Nope i know what ur talking about though that happened to me other day opened new task - run - cmd - explorer

This is completely different it wont let me run in safe mode after i log in :(
 
Could try a good old fashioned Format and reinstall of Windows.

But take the Harddisk out and move the important things off first. ;)

Would be easiest.

Yep, This machine I am on now is my Media/Games machine. And nothing on here really has any value.

Apart from game saves.. but that is hardly important.

The server holds my important stuff and backs it up onto tape when I add to the important stuff! :)

Using this method allows all of the other PCs in the house to just be used for the OS and programs. Nothing really important on them.

A prefect system. Allows me to keep Windows as clean as possible. ;)
 
depending on the type of trojan, its possible it could have infected other machines on your home network so it's probably worth running an in depth scan on all of those too
 
I've kept the internet off on that computer but i'll do a check on other computers to be sure. Where can i locate the windows format ? The adware is crazy at the minute, nearly impossible to open a window :(

I'll try that eset job now and see how it goes
 
if you have a windows dvd just put it in the drive and reboot, the windows installer should come up...if it doesn't you will need to adjust the order of the drive boot priority in BIOS by holding del (for most) when you power on, to put the DVD drive first

On most motherboards you can also press F8 to choose the drive to boot from. ;)
