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.
Installing the fix hacked wordpress Scan plugin will check all this for you, and alert you to anything that you might have missed. Additionally, it will tell you that a user named"admin" exists. Needless to say, that is your administrative user name. If you desire you can follow a link and find instructions for changing that name. Personally, I believe that a strong password is security that is good, and there have been no attacks on the several blogs that I run since I followed these steps.
No software system is resistant to bugs and vulnerabilities. Security holes will be found and guys will do their best to exploit them. Keeping your software up-to-date is a good way to stave off attacks, once security holes are found, because their products will be fixed by software vendors.
Recently, an unknown hacker hacked the site of Reuters and posted a news article that was fake. Their reputation is ruined because of what the hacker did since Reuters is a news website. The same thing may happen to you in the event you do not pay attention on the security of your WordPress blog.
Safety plug-ins can be thought of as a security checker that was complete. They check and scan the site and provide you with information concerning the weaknesses of the site.
I prefer using a WordPress plugin to get the work done. Make sure is able to do copies, has restore performance, and can replicate. Be sure that it is frequently click to investigate updated to keep pace with all additional reading new versions of WordPress. There's absolutely not any use in backing up your data to a plugin that's out of date, and not working.
