I had this same problem and it turned out that I had a few viruses on my system that I had to find with HijackThis. Reloading IE doesn't do anything because the virus is still on the system and it will infect your newly installed kernel32.dll the next time you reboot.
I cannot remember the exact procedure, but it took a while to get my system completely clean. You have to replace the infected kernel32.dll with a clean one, do a sweep with Spybot, Ad-aware, and then HijackThis. After doing this, I think my system was clean. You may also want to look for other weird-looking file names in your /system folder and your /system32 folder. Hope this helps a little.
