After running 'Anti-malware' I restarted my PC and got the wallpaper screen, but no icons, no toolbar and a window that pops up saying:

"windows cannot open this file: command.com
windows needs to know what program created it......" etc.

I have opened it with notepad but am not savvy enough to understand the contents, this is how it begins (there is much more)

 %1 device %2
&Please insert volume %1 serial %2-%3
%File allocation table bad, drive %1
Invalid COMMAND.COM
!Insert disk with %1 in drive %2
!Press any key to continue . . .

Terminate batch job (Y/N)?Cannot execute %1
Error in EXE file
"Program too big to fit in memory

No free file handlesBad Command or file name
Access denied 
Memory allocation error&
Cannot load COMMAND, system halted
!
Cannot start COMMAND, exiting
.
Top level process aborted, cannot continue


I tried many of the tips suggested online for the problem of 'no toolbar, no icons' using the Task Manager, including a system restore, but when I restarted, I got back to the same old command.com window.

Can anyone help me!?
Thanks.

ps I apologise if this topic has already been covered - if so could you please direct me to the posting?

This is for XP, correct?
It says command.com not cmd.exe?
If yes to both questions, I would think that you are still infected.
Can you boot into safemode?

command.com is the old "DOS Prompt" and it's present both in XP and Vista ofr backwards compatibility with older applications (on my XP system it's located in C:\Windows\System32). As it's not well-known or used very often, it's a convenient way for the malware to attempt to take over your system.

The text that you've gotten from the file seems to be the sequence where the program decides what to do when it fails.
My concern would be with what's trying to open this file - as it shouldn't be opened unless you've got some very old programs on the computer (from back in the Windows 98 or earlier days).

As garmanma suggests, you're probably still infected. You can get further assistance with that in the Am I Infected forum located here: http://www.bleepingcomputer.com/forums/f/103/am-i-infected-what-do-i-do/
My browser caused a flood of traffic, sio my IP address was banned. Hope to fix it soon. Will get back to posting as soon as Im able.
