And online banking in Brazil.
The security plugins they make you install down here are really obnoxious, nearly impossible to disable or remove, just like a nasty virus. If you attempt to uninstall or delete them they copy themselves right back in from who knows where. And there's a service running all the time that you can't disable, it's like the bank owns your PC now. For this reason I only do online banking in a virtual machine. I can't have their crap running 24/7 on my PC.
If you reinstall Windows, change NIC or move to a virtual machine, you have to call the bank and register your PC with the bank before you can access your account. If you sandbox the browser it doesn't work!
The security plugin of another bank we use does not support Firefox 4 yet so my wife's PC has to stay with Firefox 3, until when nobody knows. It's not like they announce "now compatible with Firefox 4" on their front page. At least the Firefox plugin for that particular bank is less intrusive than the IE plugin.
