resolution
I just registered for the site just to post this - I found a quick and easy resolution for the think-adz/brdr problem.
for think-adz: go to task manager and find a process starting with pw (it changes names from machine to machine from what I understand). Even if it doesn't begin with pw, here's how you fish it out: copy/paste every process you're suspicious of in the explorer search and find the one that is in system32 and has a Think-Adz logo. End the process and delete the file.
for brdr: the process should be called ljdsrngj.exe (this one could have a slightly different name on your system, like ljdsrngm.exe). End the process, then find it in system32 and delete it. That's all there is to it. I did it a few days ago and no problems since.
