Use equo or emerge your choice or desktop gui spritz , might need to update netscape-flash or java as well.
Wow how do you avoid the 10000 spam and scams hitting your e-mail ?
I block anything yahoo or msn or hotmail by default even if it is good for me , refuse to do business with anyone using it , never know how many times a day they have been compromised.
Easiest is if you are still paying Mc $oft by using their e-mail system maybe it is time you upgraded to gmail.com as it can import all your e-mails and send mail as firstname.lastname@example.org
if you have a name registered and you get 7gb free e-mail / attachement space + can use gmail as virtual hd to backup stuff too. gmailfs.
But heck there is about 15 000 free e-mail services out there that just works.
