How Ubuntu will block virus/spyware when I surf the web?
I am new in the Linux user after I was attacked by tons of virus and spyware when I web surf in Windows. I now install Ubuntu 9.10 in my USB drive, and run my current computer by booting from USB drive. I have a question about will Ubuntu block any virus and spyware when I web surf some dangerous website? Because I still have my hard drive with Windows, and I am not sure whether those viruses will be smart enough to stay in my Windows system and are triggered automatically when I run Windows next time?
Thanks all Linux experts in advance.
