I thought about that possibility. Another option: Yahoo! lets me set up "discardable" e-mail addresses, without creating a new account.

However, I already got rid of it, with the help of WhatsRunning. The program lists running process, and processes that will be loaded at startup, and lets me deactivate individual processes.

And the Web page has an excellent reference to any process that might look suspicious, be it spyware or an integral part of the OS.
