I have always kept up with the latest version of WordPress, but somehow somebody hacked into my site and infected it with a spamming PHP script that caused my hosting provider to suspend my account. It took them two days to fix the issue but the key thing is, I have to install WP afresh, as I don't know what PHP that they have changed.
So I want to rebuild my blog - I have backed up my database and saved it in my harddrive. I have also downloaded every file from my old site, including all of the old PHPs and themes.
My question is - is it as easy as reinstalling WP, changing the wp-config.php to point to the old database, and then reinstate the old theme?
Apologies to any grumpy experts :) I have searched around and the existing questions / explanations seem to be slightly different to what I'm after.
Any tips/advice would be much appreciated - as well as on how to safeguard my blog against any future incursions! AARGH!
