I have had two WordPress blogs hacked into previously. That was at a time when I was doing virtually no online marketing, and until I found time to deal with the situation (weeks later), these sites were penalized in the major search engines. They weren't eliminated, no matter how the evaluations were reduced.
Install the fix hacked wordpress site Firewall Plugin. Stop and this plugin investigates net requests to recognize attacks that are obvious.
The approach, and the one I recommend, is to use one of the password generation and storage plugins available for your browser. Many people like RoboForm, but go to this website I believe after a trial period, you have to pay for it. I use the free version of Lastpass, and I recommend it for those of you who use Firefox or Internet Explorer. That will generate passwords for you; you then use one master password to log in.
Harness Scanner goes seeking anything suspicious through the files on reference your website comment database and post tables. You are also notified by it for unusual plugin names. It doesn't remove anything, it simply warns you for Find Out More threats.
You may extend the plugin features with premium plugins such as: Amazon S3 plugin, Members only plugin, DropShop etc.. I think this plugin is a fantastic option and you can use it.
These are some. Thing is they don't need much time to do. These are also easy solutions, which can be carried out easily.
