Why does the immunization add unnessesary entries?
In IE6 and FF it add all these line (example):

the.007guard.com
www.007guard.com
www.install.007guard.com
*.007guard.com

The last line will cover the first 3 as well, so this is just a waste of space (and time to search through).

I have asked something about this with the "hosts" file too.
Why have:

127.0.0.1 the.007guard.com
127.0.0.1 www.007guard.com
127.0.0.1 www.install.007guard.com

When all variants can be on one line (save space/time):

127.0.0.1 the.007guard.com www.007guard.com www.install.007guard.com

Some of us have slower systems you know :-)
