Generally (and personally) speaking, I don't feel "keeping your address book contacts secure from infections", involves much more, than what's necessary to keep your entire system secure from infections. It begins and ends with you. In its shortest form ... using commonsense. It also entails having the proper security software installed and up to date. Keeping your system patched, etc., etc.
With that said, in regard to what you (specifically) asked, have a look at the article, "Important Security Information To Know", from the Windows Live Solution Center. Scroll down to "the list of things you can do to protect your online accounts and identity". If you protect your account, you protect your contacts.
About a week ago, someone posted after having had their account/address book compromised. You might want to take a look at the thread. Specifically, the "Hotmail Safety and Security Blog". Clicking on each category on the left-hand side of the page, provides additional information on the right. It may (or may not) be of further help.
Best of luck..
I have Vista Home Premium and Windows Mail and I POP3 all my email but so far I've been typing email addresses in manually (which I have written down in a small spiral notebook).
What I want to know is :
Is there a way, or ways, to keep an address book of contacts secure from infections? I mean the infections that can read the contents of your address book and send email out as if it were me.
Please let me know of any tips on this issue.
Thanks ahead for any replies.
