what precautionary measures do i take?

Here is a keylog guide, how to prevent and get rid of it http://forums.d2jsp.org/topic.php?t=15803482&f=34

Make sure you make a gold password and if you feel you're being hacked at any time the first thing you can do is send your FG to a Mediator if you wish

Change all of your passwords and stop using third party programs if that is your case.

1st scan ur PC with an Antivirue & Maleware scanner

I recommend

Avast
Avg
Microsoft security essentials

Kaspersky (if u want to pay)

For Maleware

Malewarebytes - not much can beat this

After u clean ur PC of any melicious software

I recommend changing ur Passwoed/Gold Password & Email Address (u will be required to revalidate ur account)

if i change my pw will anyone logged in to my acct be logged out?

Are you referring to the "Diablo II" client or here in D2JSP? If it is here in D2JSP, then change your electronic mail address via the link that I have provided and change your password, then create a gold password for further security:

Good luck man and I agree with Termn8tin_Cobra and thurim666, so try to run a program to clean up your machine and you can re install your machine as well for further security.

talking about d2jsp. if i change my pw and some1 else is logged into my acct will they get logged out?

If u change ur password & someone else is still currently logged into ur account

They will/should receive the "U must be logged in to access this feature" message & redirect them to the account login page when they try to open any link from ur account

get kaspersky if rich else avg + malware bit else you can clean your Hard disk (if you have your mac/nux/windows cd and can install it yourself)

then change your pw , dont take too long or too short and get few ones

If you simply just change your password, without getting rid of the keylogger, you're still in trouble.
Scan your computer, completely kill the keylog program.
