Still Can't Post on /b/, /r9k/

So the title says it all.  Ever since that last attack, my posts don't go through.  I've run the program given on the status page and it never finds Vundo.  Flushed my DNS cache.  I've run two different anti-virus programs,Threatwire, etc. etc. etc.  I've asked in /r/ and gotten good advice and still cannot post with getting "400 Bad Request nginx".

I think this is 4Chan's fault not mine, something with the way they redid the servers.  Can anyone offer me any help?

No, you don't. I know what I'm saying, and I know that most people think you can't delete the folder. Well, firstly, it IS an essential folder that makes the computer go. In fact, it's so essential, that Windows keeps a backup in the system registers. So when you delete it, during next boot, Windows will restore the folder using the system backup. You might lose some of your preferences, but frankly, I have never lost anything, nor have I met anyone who has. But devoting those ten minutes to restore the preferences every month is a small price to pay for a fast computer.
