IE 7 Protected Mode crash...

[Giftzwerg]

Using Vista Business, IE7, everything patched to current levels.

If IE7 is set to "Protected Mode", typing anything - hitting any
character - in the address bar causes IE to explode with an Event ID
1000:

Faulting application iexplore.exe, version 7.0.6000.16386, time stamp
0x4549b133, faulting module kt_dll.dll, version 1.0.0.0, time stamp
0x2a425e19, exception code 0xc0000005, fault offset 0x00004809, process
id 0x12a0, application start time 0x01c77b6fec8e75b0.

Running IE without Protected Mode checked works fine, and clicking from
link to link in PM or using the drop-down list doesn't cause the crash,
either. Only putting the focus in the address bar and hitting a key.

I know of two causes for the vast majority of such problems:
1. Incompatible add-ons: What if you right click the IE icon on the desktop
and choose Start Without Add-ons?
Or go to Start | All Programs | Accessories | System Tools | Internet
Explorer (No Add-ons).

2. Malware already installed on the computer: Help with malware

So How Did I Get Infected Anyway?
For quite a few people it's by installing Messenger Plus, whose ads for
malware don't identify the malware as such and try to convince you that you
owe it to the author. See also:

Don't ever do a "default" install of anything. Always choose Custom and see
what else is being carried along. Don't install any extras you're not sure
of.

No difference. If protected mode is enabled, IE crashes the moment you
type a key in the address bar, even with add-ons disabled.

2. Malware already installed on the computer:

The problem with this explanation is that this bug struck the very first
time I fired up IE. I (literally) opened IE, clicked in the address bar
to move away from IBM's pre-canned home page, and - whammo - IE blows up
before I got to any websites except for Lenovo's.

This bug is very strange. It's only typing in the address bar that
triggers it. Using URLs in any way from within the page or dropdowns
works just fine.
