fix interpreter for uninstall.sh

Hello all.
Im run uninstall.sh on:
Ubuntu 13.04 and Debian GNU/Linux 7.6 but get error:
# ./files/uninstall.sh 
This will completely remove Linux Malware Detect from your server including all quarantine data!
Would you like to proceeed? ./files/uninstall.sh: 4: read: Illegal option -n

./files/uninstall.sh: 6: [: unexpected operator
./files/uninstall.sh: 6: [: unexpected operator
You selected No or provided an invalid confirmation, nothing has been done!

Becasue on this system's sh linked to dash:
$ whereis sh
sh: /bin/sh.distrib /bin/sh /usr/share/man/man1/sh.1.gz
$ ls /bin/sh
lrwxrwxrwx 1 root root 4 Авг 13  2013 /bin/sh -> dash
$ ls -lh /bin/dash 
-rwxr-xr-x 1 root root 108K Авг 15  2012 /bin/dash

So I change /bin/sh to /bin/bash
What do u think?
