I've been hacked twice with wordpress plugins!

I've switched to wordpress recently that has been very easy for me to set up.

I was using plugins to create functionality that I desired, and I have now been hacked not once, but TWICE in the last 4 months.

Anyone know of a way for me to scan my godaddy server? Almost like a virus scan on a computer?

I had to remove everything, but i'm still worried there might still be a trojan sitting there somewhere.

If a plugin is on the wordpress.org site, is it safe to use? Any suggestions?

There is tons of content @ wordpress on how to secure your site as well as a few plugins... My advice is for you to delete any scripts your not using, have/change different passwords for all websites / databases etc... and contact godaddy support to see if they can track down what happened.

I haven't tried this but it might interest you

Like Hijink said above, I'd definitely contact GoDaddy Support to see if they can track down what happened.
