I have strange files and directories in wordpress directory

Hi there, last week I found some strange files and folders in my wordpress site directory as these:

Directories:
b3nkkox5a
zfrasuwk9
ykofyyy9n
c5dlwhiwy

Each of these folders contains the following files:
z2.php
z1.php
tpl2.html
tpl1.html

I copied the most recent back-up that I had. Today I see new files and directories.

Could anyone tell me what they’re and how to resolve this problem?

Virus probably

Scan your website with https://sitecheck.sucuri.net

And then install a plugin like WordFence Security plugin and be sure to check on its Options page these: http://awesomescreenshot.com/0bb5ndw30e

Its been hacked to serve ads using your server space. Contact your hosting administrator immediately. I have had this situation with 2 of my client’s websites but my hosting company didn’t help me so i had to delete all files and folders manually and updated the wp-admin, wp-includes all together with new fresh copy. Thanks
