He seems to be the only guy on the internet with the same problem as mine. I have the exact same symptoms and I found out a little more about what iexplorer.exe is doing using a program called process monitor from ZDNet.
iexplorer.exe is writing to a file called c:\windows\system32\Systemfiles\klog.dat every time I press a key on the keyboard. Clearly, I think, it's a key logger. You'll find this same directory in his combofix.exe scan. That's how I found his post through google. Now, in this directory, which my laptop and other normal computers don't seem to have, was created on June 11. Inside, besides klog.dat, there is a file called taskmgr.exe. Neither Symantec nor Windows Defender recognizes this as malware but it's pretty darn suspicious.
After I quarantined this file using Symantec, the iexplore.exe file still boots and still writes to klog.dat, so some other file is doing the dirty work.
Have you guys been able to find out any more info?
Thanks for your help.
