Hi Arymond, sorry I don't really have any other suggestions for you at this point other than to either switch to MoI v3 or to back up your important data and wipe/reformat your drive and do a fresh install of Windows.

It seems that you're Internet Explorer installation has gotten really messed up, and from some of those comments that I read it looks like that particular anti-virus/anti-spyware system could be what got things messed up in the first place.

You might check out if you have any system restore checkpoints from some time when your system was working properly and try to do a system restore back to then.

Maybe it could be worth a try to install IE9 now without that other system running and see if you end up with an ok installation after that.
