Some hints where to get commercial software free of charge:
If you need an antivirus software for windows, you can download a campus-licensed McAfee VirusScan Enterprise from the ZDV software page by logging in with your ZDV account.
The Dreamspark program provides WSI employees and students (ZDV account needed) with Microsoft software. Almost all Microsoft software is available via this program, except for Microsoft Office. You are entitled to software from this licensing program, as long as the software is not used for commercial purposes or purely administrative tasks. Access to a windows system is needed for downloading software, as the download process uses a Windows-based download manager.
