Yup, some guy with a heavy accent wanted me to open my computer so he could eliminate some secret, undetectable virus - I asked for a call-back number "1 877 ..." oops, connection lost
What a loser! After I told him not to phone her again, he started insulting me, and then told me to hang up!!!! After I vented using words I shouldn't have, I did just that, hung up. If someone claims to be from Microsoft, or anywhere, and then asks you for info, it will never be legit.
