I have Internet Explorer 6, and tried to upgrade to 7. After I installed it from microsoft.com, I began setup. After a while, it said that it could not be installed and that I should restart to undo everything. So I did. Once my computer rebooted, I started getting messages about things not being able to start because file iertuti.dll or somehting like that was missing. I got this message for a bunch of things like Windows Media Player, Norton, etc. So I tried the last known good configuration thing, and that didn't work. Then a friend emailed me the file, and I put it into the System32 folder, and now the message doesn't come anymore. But, Internet Explorer still doesn't work, every page says page cannot be displayed. Don't know if this matters, but I got some annoying malware that might have something to do with this. Can anyone help me?
