Not a virus, just a webpage creator being stupid. 2 ways to fix. (assuming creator was stupid, not malicious)
1. in IE, goto TOOLS, OPTIONS, PROGRAM, then select RESET WEB OPTIONS.
If that doesn't work, then try to allow IE to repair itself. (2nd option)
2. goto ADD/REMOVE PROGRAMS. select UNINSTALL IE. This will pop up an options box. Select REPAIR IE. With this, IE won't be uninstalled, it'll just look for and try to repair altered or corrupted files back to its original installed state.
Hope it helps
