Hosting support

Hai,
I have a problem with file uploading
I have a upload files content type where user upload image,doc,pdf files.
I know that it doesn't allow .exe file if file extension are .exe.

The problem is that when i rename .exe file extension as .jpg .
It is not showing any error simply it is uplopading the file.
It is a big security issue of my site.
How to check within file and send error message not to upload such files.

Hey guys:

I've been checking around online for web hosting providers, and I've come across a few. I wanted to get the thoughts of some people
here to see if they have used siteserving and/or if they have anything to say about them? They look good... so I want to use them...

On another note, I've got a few Drupal driven websites, which are starting to get dated, and want to upgrade to the latest version of
drupal, so.. can anyone suggest the best path to run from Drupal 5.x to 8.x ?

Thanks guys!!

Can someone recommend a good hosting company for Drupal? I am looking for one that is carbon neutral that will let me use Drush on a shared hosting plan.
Thank you

We've tested numerous setups to optimize Drupal for speed and stability. What have you found to work best?

So far our best setup has involved using Debian, with varnish, CDN and then SSD for the SQL database. Obviously that's a bit more complicated than the average user wants, and certainly costlier.
