Unable to remove boot sector virus

I have a boot sector virus and can't get rid of it. I tried different boot setup disks, I ran antivirus software, boot virus removals and repairs without any success. Each effort ends with a boot sector virus alarm and Write option Y/N. N results in a message that the writing of the boot record failed and Y just carries the virus along perpetuating the problem.

I use Vista HP SP2 with all updates, AVG 2011 updated today, IE8 updated. What else should I mention? Formating the HD of course does not get rid if the malice either, I tried a secure delete which fills everything with zeros. Low level format? I tried Killdisk, Rootrepeal, mbr.exe, fdisk.zip, ccsetup300.exe, tdsskiller.zip, gmer.exe etc. I admit to not being sure what to do next in some of these last software cases because the results I get don't look the same as shown on the relevant web sites. The site may show the apparent villains in red but I don't get any red items or I receive a summary of so many files, processes, modules ect. and zero infections or suspicious items.

I have the same problem. Boots up to screensaver - no icons. Had to go thru safe-mode which eventually let me boot up in regular mode. I have a troj/TdlMbr-A virus that my Webroot Antivirus has detected but won't delete or quarantine. It has been running for 15 hours now. Afraid to turn it off because I may never get back on. I have Kaspersky Antivirus that I haven't used. Would this work? Do I need to buy a trojan remover? Which one? How do I get it out of my system? Thanks for any help.
