Dear specialists,
On my site appeared files like:

\media\com_easyblog\scripts\easyblog-3.9.17809.static.js.backup
\media\com_easyblog\scripts\easyblog-3.9.19335.static.js.backup
\media\com_easyblog\scripts\easyblog-3.9.19775.static.js
\media\com_easyblog\scripts\easyblog-3.9.19025.static.js.backup

Each of them rather heavy, 1,18 mb, so the site strongly put on its weight
How to get rid of them?

(I use EasyBlog 3.9.19775)
