I use Microsoft Security Essentials.. If this will not find anything, I'll download malwarebytes as you recommend, thanks.
never trust a single scanner. use a paid scanner with a good detection rate and malwarebytes as an additional "run when needed" scanner. malwarebytes is well known as a scanner with a high detection rate.
you can upload suspicious files to virustotal and let them check the file with the most known scanner to be sure that nothing will undetected.
my account is not in the list, too and i never use passwords for more than one website so not really a problem. they just need to reset all passwords and everyone is fine.
but how legit is the list? could be old, fake, or just a way to legit the so called hack

dont belive in it.
