Appears to be a Google hijack

OK, I renamed scecli.dll and moved the new file in, no problem. Then when I tried to rename proquota.exe, the response back was that no such file existed, so I just copied the good file to system32.

I then ran ComboFix. After running, it restarted, and then the box said something like "can't find whitedir" and crashed (it was up only very briefly) and did not make a log. I then ran ComboFix again. This time it didn't restart the computer after the scan and did make a log. The log is here:

And, Google results are not being hijecked at the moment!

What else do I need to do at this point?

OK, it looks like those two files are in place now. You may delete them from the C: drive now as they are in system32.

Good job. Your log is clean.

Are there any problems now? If none, go to Start->Run, copy/paste in combofix /u and hit OK to remove it. You should be set to go.
