I have had two WordPress blogs hacked into in the past. That was at a time when I was doing very little internet marketing, and until I found time to address the situation (months later), these sites were penalised in the search engines. They were not removed, but the rankings were reduced.
Since scare tactics seem to be at the very least start thinking about the issue, or what compels some people to take fix malware problems free a bit more seriously, let me shoot a few scare tactics your way.
There are ways to pull off this, and a lot of them involve re-establishing databases and much more and FTPing files, exporting and copying. Some of these are very complicated, so it is imperative that you go for the right one. Then you might want to check into using a plugin for WordPress backups, if you're not of the technical persuasion.
For me it's a WordPress plugin. They're drop dead find out here easy to install, have all the features you need for a job such as this, and are relatively cheap, especially when compared to having to employ someone to have this done for you.
Safety plug-ins that were all-Rounder can be considered as a security checker that was full. They you can try these out give you information about the weaknesses of the site and scan and check the website.
But realize that online security is. Do not only be the check my source type, consider action to begin protecting yourself. Don't let Joe the Hacker make your life miserable and turn everything in creating come crashing down in a matter of moments, that you've worked so hard.
