IE9 Starting Rundll32.exe Files Upon Exiting It,killing Cpu And Memory

I am running the 64-bit version of Windows 7 along with IE9. I have found that a problem exists for both the 32-bit as well as the 64-bit version of IE9. I find that for the 32-bit IE9 there are 2 "iexplore.exe *32" files running when the program is started. With the 64-bit version of IE9 there are 2 "iexplore.exe" files running but that's not the problem.

I have found that when I have checked the box "Delete browser history on exit" (Tools - Internet Options - General tab - Browsing History) this sets off the problem on IE9 exit. Both of the iexplore.exe disappear but 2 new files rundll32.exe (*32 for the 32 bit version) appear. These 2 new files run for several minutes at 100% cpu and each will have up to 680Mb of memory. If I go back and uncheck the "Delete browser history on exit" these files, rundll32.exe do not appear and the problem goes away.

It appears the problem is with "Delete browser history on exit" function. I've been using IE9 since it came out and never had my computer, which is now freezing while the rundll32.exe are running, happen before. Ran Malwarerbyts, Super anti-spyware, Spybot, MS Essentials, Advanced system care (Just the Malware finder), Argente utilities (Just the Malware finder), System Mechanic (Just the Malware finder) in safe mode and nothing. I also am not using registry cleaners.
