I just installed a package (dansguardian in this case) and apt told me that I had unmet dependencies.

# sudo apt-get install dansguardian
Reading package lists... Done

The following extra packages will be installed:
  clamav clamav-base clamav-freshclam libclamav6 libtommath0

The following NEW packages will be installed:
  clamav clamav-base clamav-freshclam dansguardian libclamav6 libtommath0

Do you want to continue [Y/n]?

So I installed it and the dependencies. So far so good.

Later on, I decide that this package just isn't the package for me, so I want to remove it and all of the other junk it installed with it since I'm not going to be needing any of it:

# sudo apt-get remove --auto-remove --purge dansguardian

The following packages will be REMOVED:
  dansguardian

After this operation, 1,816 kB disk space will be freed.
Do you want to continue [Y/n]?

However it is only removing that one specific package. What about clamav clamav-base clamav-freshclam libclamav6 libtommath0? Not only did it not remove them, but clamav was actually running a daemon that loads every time the computer boots. I thought that --auto-remove would remove not only the packages, but also the dependencies that were installed with it.

So basically, without going through the apt history log file (if I even remember to do so, or if I even remember that a specific package I installed 3 months ago had dependencies along with it), is there a way to remove a package and all of the other dependencies that were installed like in this case?
