i hear good things about Avast.
Onto another setup problem.
I have Vista Home Premium and have set up a jap keyboard sos I can do kanji etc, but in my windows mail, some of the characters aren't displaying properly. The Interenet explorer sems to do ok, although there is the occasional site that doesn't work. I can read and type emails in Japanese, just some of the names are off.
Beginning to hate Vista a little bit already...
Managed to work it out. All is good now. Just had to change the region seting a little so it assumed that script that wasn't encoeded properly was Japanese and it works fine now! HURRAH!
