Don't reinstall windows, that's rediculous. Fix the problem...

You can probably just remove all references to mwsbar.dll in the registry (regedit.exe), however, the easiest way is to

Run autoruns http://www.microsoft.com/technet/sysinte...

It will show you everything that starts up automatically...from there you can disable, delete, etc.

You should also run some spyware removal tool (http://www.lavasoftusa.com/ or http://www.safer-networking.org/en/index...

There is an article about removing mwsbar.dll here: http://ask-leo.com/mwsbardll_what_is_it_...

NOTE: I've never had mwsbar.dll on my machine nor run the suggestions at ask-leo, however, they seem straight forward, and sould like they should work...

As far as logging into Yahoo games, have you tried running firefox (rather than IE)? You can download Firefox here: http://www.getfirefox.com

Your computer is out of whack. Do a clean install of windows. If your computer came with a master boot disk then use that. Be sure to backup file you want to keep because its going to erase them. Also make sure you format your drive before the install.
