After logging in i can only see a black screen with cursor.

I can access everything through ctrl/alt/delete task manager.

I cannot download anything eg antivirus.

the brontok.a page continually pops up.

Bitdefender has a tool just for that:

But if by chance the above tool doesn't remove it, A-Squared Free should.

Brontok .a virus?norton internet security 2008

It arrives as an attachment of e-mail named kangen.exe ("kangen" word itself means "I miss you so much"). When Brontok is first run, it copies itself to the user's application data directory. It then sets itself to start up with Windows, by creating a registry entry in the HKLM\Software\Microsoft\Windows\CurrentV... registry key. It disables the Windows Registry Editor (regedit.exe)and modifies Windows Explorer settings. It removes the option of "Folder Options" in the Tools menu so that the hidden files, where it is concealed, are not easily accessible to the user. It also turns off Windows firewall. In some variants, when a window is found containing certain strings in the window title, the computer reboots. Using its own mailing engine, it sends itself to email addresses it finds on the computer, even faking the own user's email address as the sender. The computer also restarts when trying to open DOS window (Command Prompt) in Windows and prevents user from downloading files. It also pop ups the default Internet browser (usually Microsoft Windows Internet Explorer, Mozilla Firefox, Opera or Netscape) and loaded a web page (html) which is located in the My Pictures (or Pictures folder on Windows Vista) folder.Good luck with this one you might have to reformatt.,
