Is your name George by any chance?
This sounds a bit like the Hacked By Godzilla infection and it could possibly be the same sort of thing. If that's the case, then you're simply facing a hijacker and not an actual hacker. Either way, your IE is only a small side-effect that we will deal with later. It's very easy to fix, but as long as you're infected, the name will keep changing.
So, first, I would like you to download Deckard's System Scanner to your desktop:
http://www.techsupportforum.com/sectools/Deckard/dss.exeNote: you need to be logged onto an account with administrative privileges.
Since you are a Vista user, right-click on the DSS file and click on Run As Administrator.
Close all applications and windows.
When the scan is complete, two text files will open:
main.txt (maximized) and
extra.txt (minimized)
Copy and paste the contents of these two files in your reply. You may need to use multiple posts.
And don't forget to run the Kaspersky scan like
evilfantasy suggested.
