Tuition fees in Germany are already next-to-nothing - around 150€ - 250€ per semester.
As to a better way? Either going to each machine with a USB stick and cleaning or going to each machine and replacing the hard drive (more secure, but more expensive and time consuming).
As the malware spreads over the network, you have to disconnect the machine from the network, until it is clean, therefore any remote management tools are useless.
